electric activity of the brain

Electric activity of the brain is detected by the scanner built in helmet.

Activation of the parietal lobe is also evident in studies using magnetoencephalography (MEG) which traces electric activity of the brain.

The CAT quickly came into use in research labs all over the world, marketed by Technical Measurements Corp., advancing the study of the electric activity of the brain (enabling, for example, the clinical detection of deafness in newborns).

These included Dimi-S (also known as Sexophone, 1972), where sound generation is based on the electric conductivity of the skin, and Dimi-T (aka Electroencephalophone, 1973), where the sound control is based on a signal generated by the electric activity of the brain.
