Abstract
Electrical activity of the brain is analysed by the application of a repetitive stimulus so as to evoke a steady state response, changes or differences in the steady state response being used as a measure of said electrical activity. The spatial distribution of the activity can be displayed as a topographical representation of the brain, which representation can be updated so as to provide a substantially real-time display. A neuro-psychiatric workstation incorporating such a display can be used for instance for various research purposes.
