Brain function is typically measured and visualized using EEG and MRI, but EEG suffers from low spatial resolution and fMRI, because it detects changes in blood flow, suffers from low temporal resolution. A new technique that may open doors for neuroscientists to study how the brain functions and for neurosurgeons to improve their techniques involves pre-placing electrodes in the brain to detect electrocorticographic (ECoG) signals.
Because the researchers believe that the new imaging technique cannot be properly explained in words, they chose to publish in JoVE, The Journal of Visualized Experiments, a publication that uses the power of video to demonstrate complicated procedures.
