Neurophysiologists from Sechenov University recorded brain activity of Russian-speaking volunteers during writing and speaking. They captured weak signals associated with the work of a person's "inner voice," Skoltech reported.
The results of this work expand the knowledge base necessary for creating neurointerfaces capable of "reading minds."
Neurointerfaces will be able to recognize the user's intentions: to move a prosthesis, to type text.
The scientists conducted an experiment on two patients suffering from epilepsy. They implanted electrodes into their brains and recorded its electrical activity using an electroencephalograph.
Analysis of the results helped determine which areas of the brain are involved in motor skills and speech, including the formation of the "inner voice." In particular, changes were recorded in the superior frontal gyrus and superior temporal gyrus.
These studies will help create systems that "read the minds" of people with disabilities.
