EEG to Play a Role at Next Week's Olympic Festivities
The Winter Olympics in Vancouver are fast approaching and InteraXon, a Toronto based company, has been hired to help bring the rest of Canada into the spirit. 
InteraXon has developed its own consumer grade electroencephalograph (EEG) brain to computer interface and has been searching for applications where it can be useful. So, in the traditional Olympic spirit of national pride and technological gimmickry, the Ontario Ministry of Tourism asked the firm to control the light on three major landmarks in the province using pure thought from a group of people streaming from the West.
The Globe and Mail explains in an article from last week:
When visitors to the Ontario Pavilion next month put on the headphone-like brainwave sensors, their mental activity will be communicated to control systems that light up each of the sites. Slow your mind and the lights dim as the brain starts producing lower-frequency alpha waves. Higher-frequency beta waves of an alert mind make the lights come to life – comet trails stream down the shaft of the CN Tower; backlit Niagara Falls starts to glow in shades of purple and red; Parliament Hill springs out of the shadows.
Here's an interview with COO of InteraXon on Canada's Business News Network:

SUMAVEL DosePro Migraine Treatment Injection System Going on Sale in US
Having received FDA approval last July, Zogenix out of San Diego, California is bringing to market its SUMAVEL DosePro sumatriptan delivery system for the treatment of oncoming migraines and cluster headaches. The needle-free device delivers the drug subcutaneously, bringing both speed and efficacy when oral pills are a poor option.
From the press release:
SUMAVEL DosePro delivers subcutaneous sumatriptan, a treatment that provides migraine relief starting within 10 minutes for some patients*, in a first-of-its-kind needle-free delivery system. SUMAVEL DosePro is expected to be available at most retail pharmacy outlets this month.SUMAVEL DosePro offers other practical benefits. Approximately 30 percent of patients report vomiting as a symptom of migraine attacks, and the vast majority of attacks are also accompanied by nausea. During these episodes, oral therapies may be an impractical treatment option. Further, while most forms of triptans can be effective when taken early in a migraine attack, patients who experience rapid onset of migraines, or those that occur upon waking may not always achieve the fast relief they would like from tablet and nasal forms.
Quickly absorbed subcutaneous sumatriptan may offer an alternative for these patients, although until now, it was only available in a needle-based system. New SUMAVEL DosePro delivers sumatriptan subcutaneously (under the skin) without a needle, which can offer fast relief in a patient-friendly delivery system.
*In two well-controlled clinical trials (N=1104) with patients experiencing moderate or severe pain and one or more migraine symptoms, the efficacy of subcutaneous sumatriptan versus placebo was evaluated. In these clinical trials, 16 percent of patients achieved relief within 10 minutes versus 4 percent for placebo; 70 percent of patients achieved relief at one hour versus 22 percent for placebo (P<.001); and 82 percent of patients achieved relief at two hours versus 39 percent for placebo (P<.05)

Rehab Gaming System Helps Kids With Cerebral Palsy
Researchers from Indiana University and Rutgers have been testing whether a specially designed video gaming system can help children with hemiplegic cerebral palsy improve their hand coordination. The results are promising, and underscore the value of modifying underlying technologies to suit the needs of the patients.
The three study participants were asked to exercise the affected hand about 30 minutes a day, five days a week using a specially fitted sensor glove linked to a remotely monitored videogame console installed in their home. Games, such as one making images appear ("sliders") were custom-developed at Rutgers, calibrated to the individual teen's hand functionality, included a screen avatar of the hand, and focused on improvement of whole hand function."Popular off-the-shelf games are targeted to people with normal hand and arm function and coordination. These games don't work for or benefit those with moderate-severe hemiplegic cerebral palsy and many other disorders that affect movement. They just aren't made to be used by or improve hands that can't pinch or grasp" said Golomb [Dr. Meredith R. Golomb, Indiana University School of Medicine associate professor of neurology].
In the future, physical therapists could remotely monitor patients' progress and make adjustments to the intensity of game play to allow progressive work on affected muscles.

MRI Diffusion Tensor Imaging May Predict Onset of Alzheimer's
Scientists have been looking for years into methods that can distinguish a healthy brain from one that is in early stages of Alzheimer's. Traditional MRI doesn't reveal how water moves within the white matter, but diffusion tensor imaging (DTI), a method where specific radio frequencies and magnetic field pulses are applied in a predefined manner, can reveal the direction of water diffusion to uncover some of the physical processes within the brain. Now researchers from Tor Vergata University and Santa Lucia Foundation, both in Rome, have shown that diffusion tensor imaging is a better predictor of oncoming memory loss when compared to traditional MRI measurement of hippocampus volume.
Basic methods used in the study from the published abstract:
In this cross-sectional study, 76 healthy individuals (44 male and 32 female), ranging in age from 20 to 80 years, were recruited from universities, community recreational centers, hospital personnel, and patients' relatives from 2005 to 2008. These individuals were submitted to a 3-T MRI protocol with a whole-brain T1-weighted and diffusion-weighted scanning and a neuropsychological assessment. For each subject, we calculated the volumes of the total brain (gray + white matter) and hippocampi. The segmented hippocampi defined the binary masks where mean values of mean diffusivity (MD) and fractional anisotropy (FA) were calculated. Neuropsychological evaluation included tests of verbal memory (15 minutes delayed recall of a 15-word list) and visuospatial memory (20 minutes delayed reproduction of Rey complex figure).

Genetic Engineering and Light Team Up to Control Neuron Activity
Scientists at MIT have discovered a method to shutdown specific neurons with different colors of light. The scientists isolated two genes from bacteria and fungi that are light-sensitive. They then used a virus to insert these genes into neurons. When these genetically engineered neurons were exposed to light, the light-activated proteins lowered the neurons' voltage, preventing them from activating. One of the genes responds to yellow light, and the other responds to blue.
Current methods to directly control neuronal activity rely on over-stimulating neurons (e.g: DBS), rather than inhibiting their activity. While similar methods of light-sensitive gene delivery have been used in the past, this new method allows specific control with different colors of light.
Here's more from the press release:
“Silencing different sets of neurons with different colors of light allows us to understand how they work together to implement brain functions,” explains Ed Boyden, senior author of the study, to be published in the Jan. 7 issue of Nature. “Using these new tools, we can look at two neural pathways and study how they compute together. These tools will help us understand how to control neural circuits, leading to new understandings and treatments for brain disorders — some of the biggest unmet medical needs in the world.” Boyden is the Benesse Career Development Professor in the MIT Media Lab and an associate member of the McGovern Institute for Brain Research at MIT.

Promising Results Released in Controlling Epilepsy via Deep Brain Stimulation
Last week at the American Epilepsy Society Meeting in Boston, Medtronic and NeuroPace released results of clinical trials studying the benefits of the firms' competing Deep Brain Stimulation (DBS) systems to control symptoms in patients suffering from severe epilepsy. The findings seem to foreshadow the future in which the technology might become a standard treatment option for patients who continue to develop seizures despite adequate medication regiments, and in some cases, vagus nerve stimulation or even ablative surgery.
From Medtronic's announcement:
The results of the study show improvement over time with median (mid-point) reduction in seizure frequency of 41 percent at one year, 56 percent at two years, and 68 percent at three years of DBS therapy, in conjunction with antiepileptic medications, compared to baseline. Of the original 110 patients who received DBS implants in the trial, 91 remain active in the study, including some who have received DBS therapy for more than five years. At the time of this data analysis, 102 patients had completed two years and 57 had completed three years of therapy. In addition, 14 patients (13 percent) experienced seizure free intervals ranging from six months to more than four years.The study, known as SANTE® (Stimulation of the Anterior Nucleus of the Thalamus in Epilepsy), is a prospective, randomized, double-blind pivotal study to evaluate the use of DBS therapy for patients with medically refractory epilepsy with partial-onset seizures, a form of epilepsy that does not respond well to antiepileptic drugs.
The types of adverse events reported in the study were consistent with known adverse events associated with epilepsy and implanted DBS systems. There were no serious unanticipated device-related adverse events. At the conclusion of the unblinded phase of the study (first 13 months), 4.2 percent of adverse events (a total of 34 events) were serious and device-related. That rate declined over time. Of the 34 events, the most frequent serious device-related events were lead(s) not within the target (nine events) and implant site infection (eight events). Depression and memory impairment were reported more frequently in active stimulation patients compared to no stimulation (controls) although objective neuropsychological assessment did not show any statistical differences between active or no stimulation (control) groups.
The SANTE study involves stimulating the left and right anterior nucleus of the thalamus – the brain’s central message and relay station – with Medtronic DBS Therapy for Epilepsy in conjunction with epilepsy medications. Patients in the study have had epilepsy for an average of 22 years and 54 percent of the 110 implanted patients had previously undergone resective surgery and/or vagal nerve stimulation therapy. Benefit was seen in patients with prior history of vagal nerve stimulation or previous epilepsy surgery as well as patients without such history.
From a statement by NeuroPace:
The trial demonstrated a statistically significant reduction in seizure frequency in the treatment group (responsive stimulation active) as compared to the sham stimulation group (responsive stimulation inactive). During the last two months of the three month blinded evaluation period of the study, people in the treatment group experienced a mean percentage reduction of 29 percent in their disabling seizures compared to 14 percent reduction for those in the sham stimulation group. In the long term, open label period of the trial, at least 12 weeks of data were available for 171 study participants; 47 percent of these subjects experienced a 50 percent or greater reduction in their seizure frequency based on their most recent 12 weeks of data, as compared to their baseline.The trial also demonstrated a serious adverse event rate less than comparative surgical procedures. There were no serious unanticipated device related adverse events reported in the trial. There was no difference between the treatment and sham stimulation groups when comparing the rate of adverse events, including depression, memory impairment and anxiety.

Vocalizations Return to Paralyzed Man, Via Wireless Brain-Computer Interface
Locked-In Syndrome is one of the most terrifying brain lesions -- leaving patients aware but almost entirely without the power to move. Now, a collaboration of American academic researchers has implanted a wireless brain-machine interface, developed by Neural Signals of Duluth Georgia, into a locked-in subject who is almost completely paralyzed.
The system uses brain electrodes to read signals meant for jaw and mouth muscles. An FM radio is used to transmit these brain signals to a computer, which transforms them into recognizable sounds. Currently the system is only able to produce vowels, but with more electrodes and more powerful algorithms it should be able to scale up to fully vocalized words.
From the article abstract in PLoS ONE:
BackgroundBrain-machine interfaces (BMIs) involving electrodes implanted into the human cerebral cortex have recently been developed in an attempt to restore function to profoundly paralyzed individuals. Current BMIs for restoring communication can provide important capabilities via a typing process, but unfortunately they are only capable of slow communication rates. In the current study we use a novel approach to speech restoration in which we decode continuous auditory parameters for a real-time speech synthesizer from neuronal activity in motor cortex during attempted speech.
Methodology/Principal Findings
Neural signals recorded by a Neurotrophic Electrode implanted in a speech-related region of the left precentral gyrus of a human volunteer suffering from locked-in syndrome, characterized by near-total paralysis with spared cognition, were transmitted wirelessly across the scalp and used to drive a speech synthesizer. A Kalman filter-based decoder translated the neural signals generated during attempted speech into continuous parameters for controlling a synthesizer that provided immediate (within 50 ms) auditory feedback of the decoded sound. Accuracy of the volunteer's vowel productions with the synthesizer improved quickly with practice, with a 25% improvement in average hit rate (from 45% to 70%) and 46% decrease in average endpoint error from the first to the last block of a three-vowel task.
Conclusions/Significance
Our results support the feasibility of neural prostheses that may have the potential to provide near-conversational synthetic speech output for individuals with severely impaired speech motor control. They also provide an initial glimpse into the functional properties of neurons in speech motor cortical areas.
Here's the visual and audio feedback as presented to the locked-in man during tests:

Getting Closer to Decoding Brain Activity from EEG
Admit it: In medical school, you never really understood what makes an alpha wave an alpha wave, or why it's different than a delta wave. You thought maybe some hardcore neurologists knew, but it turns out that was probably wishful thinking.
The truth is, Electroencephalogram (EEG) readings taken from the scalp are substantially modulated from their original source, but clinicians never knew exactly how the signal changes when it passes through that thick skull of ours. Now researchers from Max Planck Institute for Biological Cybernetics in Tübingen, Germany have a better handle on how EEG waveforms from the scalp relate to what the brain is producing.
By combining recordings of both EEG and individual neurons in trained monkeys, [Kevin] Whittingstall and [Nikos] Logothetis found that a combination of specific waves in the EEG could indeed reliably predict the activity of cells in the brain. They presented different movie clips consisting of everyday natural scenes to trained monkeys. While the monkeys watched, their brain activity was recorded via EEG and via electrodes that were placed directly on the neurons, thus allowing for a direct comparison between data sets. Specifically, they observed that the firing pattern of cells was highest during periods where bursts of ‘fast’ EEG activity were embedded within the slow-wave EEG. As the degree of this so-called ‘frequency band coupling’ changed, so also did the cells firing rate."We succeeded in identifying which aspects of the EEG best represent changes in the activity from a population of neurons in the brain", explains Kevin Whittingstall. "With this information, we can now move to better understand the cause of abnormal EEG waveforms in patients with certain neurological disorders."
It's about time! And all it took were some skull-less monkeys.

GE Releases Software to Aid in Image Guided Interventional Procedures
Interventional radiologists, radiation oncologists, neurosurgeons and others now have a new tool to help them target tumors, AVMs, and other hot spots using visual data from multiple sources.GE has just released the VolumeShare 4 multi-modality volume viewer for its Advantage Workstation software suite. The system brings together imaging data from various diagnostic modalities to aid in planning and during interventional procedures.
The VolumeShare 4 multi-modality volume viewer software integrates 3D images from GE’s Innova® interventional imaging system, as well as CT, MR, PET and PET/CT datasets to support new interventional visualization functions and analysis that are targeted for planning and navigation during image-guided interventional therapies, as well as monitoring the procedure results.It is now possible to use the multi-modality images not just for diagnosis, but to steer the interventional gantry to different angles around the patient. An image that has already been acquired can be used to guide the gantry to the appropriate position for acquiring the real time image. Additionally, Advantage Workstation VolumeShare 4:
Provides images to show needle entry point and the final target, and allows the clinician to see all the anatomy in between to plan the best possible pathway. Combines images from other 3D modalities, such as CT and MR, to show things that X-ray may not reveal, allowing for more effective guidance. Enables "before" and "after" comparisons, i.e., comparing an X-ray image to either an MR image with physiology, or comparing a CT image with anatomy, or comparing the uptake of a radioactive PET tracer to blood flow in a region.

GaitAid Augmented Reality System Might Help with Walking, Gait
Walking can be difficult for patients who have conditions that interrupt or diminish feedback from the somatosensory system. Timing of movement can, therefore, be severely impaired in people with Parkinson's, cerebral palsy, and multiple sclerosis. An Israeli scientist used his knowledge from the research in helicopter navigation software to develop a system that provides audio and visual feedback cues that seem to help in improving gait and walking.

Image Recognition Technology to Expand Abilities of Microsoft's Digital Camera Device
Microsoft has partnered with Oxford Metrics Group (Oxford, UK), a company specializing in computer vision applications, to further develop Microsoft's ViconRevue (formerly SenseCam) digital camera-like gadget. The device continuously snaps a picture every 30 seconds, hence it might be worn around the neck by patients with memory problems (i.e. Alzheimer's, s/p hypoxic/ischemic encephalopathy). The device is thought to help people refresh themselves on the activities of the past day. With Oxford Metrics Group's software built-in, the ViconRevue should be able to perform some pretty nifty tricks by recognizing objects and faces in its field of view.

Neuropace Implantable Epilepsy Device Showing Positive Signs in Initial Clinical Study
A clinical trial is underway for a neurostimulator implant that monitors brain activity and then sends an electrical jolt designed to prevent an epileptic seizure. Neuropace has developed the RNS system in Silicon Valley, and is undergoing clinical trials with more than 200 patients across the US. It is being reported preliminarily that RNS implant is effective in treating seizures through the mechanism of responsive stimulation. In this protocol regions of the brain demonstrate erratic electrical signals before a seizure. Through counter electrical stimulation, the seizure can be prevented or minimized.
The RNS is placed under the skull and the electrodes are connected to relevant regions in the brain in order to provide stimulation. The device is controlled wirelessly through an adapter on a laptop which allows a clinician to view the patient's electrocorticographic (ECoG) activity in real-time and the ability to upload the patient's ECoGs that have been stored in the RNS neurostimulator.
The purported design advantage with the RNS system versus other anti-epileptic systems currently employed is that the RNS system does not constantly electrically stimulate the brain, but rather monitors specific regions in the brain for an uptick in electrical activity and only shocks when there is indication of an upcoming seizure. This means the RNS is monitoring more and shocking less.

Brio DBS System Wins EU OK for Parkinson's; First Person Implanted with the Device
St. Jude Medical has received European approval to market the world's smallest implantable deep brain stimulator to help control the symptoms of Parkinson's disease. The Brio device weighs 29 grams (~1 ounce) and has a 10 millimeter profile. The battery is rated to last for up to 10 years with recharges, so the first patient, a 67 year old German man, recently implanted with the device won't need a replacement for up to a decade, maybe until 2019.
From the announcement:
The Brio DBS system delivers mild electrical pulses to specific targets in the brain, stimulating the structures that are involved in motor control. The system consists of a neurostimulator – a surgically implanted battery-operated device that generates the electrical pulses – and leads which carry the pulses to the brain to influence the irregular nerve signals responsible for the symptoms of Parkinson’s disease.In addition to its small size, the Brio neurostimulator has the longest battery life of any rechargeable DBS device currently on the market with a 10-year battery longevity approval. For patients this means the device should provide sustainable therapy and maintain a reasonable recharge interval for at least 10 years of use at high settings. The device’s battery longevity may also maximize the time between device replacement procedures.
The Brio neurostimulator also features:
Constant current circuitry that automatically adjusts to deliver consistent therapy over time.
A dual header that accommodates two leads, allowing for bilateral stimulation from one device.
High power capability, making it an appropriate choice for patients who require high energy settings to control their symptoms.
A rechargeable battery that can be easily charged through a portable, wireless charging system, allowing patients the freedom to recharge comfortably while doing other activities. Additionally, St. Jude Medical has recently received CE Mark approval for the Guardian™ Burr Hole Cover System, a DBS system component that allows physicians to efficiently secure the electrical leads. The Guardian System is compatible with all St. Jude Medical DBS leads.

Sleep Monitoring System to Take Home
European research center IMEC has developed a sleep staging system that can record EEG signals in the comfort of one's home. The prototype device has already been successfully tested at the University Hospital Center (CHU) in Charleroi, André Vésale Hospital (Belgium).
The system consists of a head band with three sensor nodes measuring 2 EEG-channels (electroencephalogram) to monitor the brain activity, 2 EOG-channels (electro-oculogram) to monitor the eye activity and 1 EMG-channel (electromyogram) to monitor the chin muscle activity. These 5 signals provide the required information for sleep staging according to the Rechtschaffen and Kales standard. The sensor nodes integrate IMEC's proprietary ultra-low power biopotential read-out ASIC (application-specific integrated circuit) to amplify and filter the 5 different ExG signals. The measured ExG signals are wirelessly transmitted to the recording computer. No additional wires from the head to the body or from the head to the recording device are needed, making the system comfortable to wear. The system is optimized for low power resulting in 12 hours autonomy.The system has been validated in a controlled clinical environment and benchmarked with state-of-the-art ambulatory monitoring equipment. 12 healthy volunteers were enrolled in the study, and were monitored for a complete night using the wireless and the reference systems set-up in parallel. At the end of the study, the signals were given to a sleep expert for blind scoring, leading to two hypnograms for each subject. From the hypnograms, sleep statistics such as percentage of sleep time in each stage were deducted, and compared for the two systems. Hypnograms were also compared directly for similarity. The analysis proved the potential of wireless sleep staging systems to replace the current monitoring systems.
