Localizing Brain Activation Through EEG

Through the use of a signals present at a specific frequency, brain centres responsible for responding to different types of stimuli can be isolated in their activation. For example, using visual stimuli at 12Hz in foveal and peripheral regions, activation in different regions of the visual cortex were isolated and plotted on 2-D scalp maps through electrical activity recorded on a 64-channel EEG system. This can be monitored in real time through the use of brain computer interfaces, which have
