High-resolution wideband electroencephalograph based on nanosensors

A new hardware-software system for recording high-resolution electroencephalograms using noiseless nanosensors is presented. This system is able to record electroencephalograms with a sampling frequency of 16 kHz in the frequency range from 0 to 3.5 kHz at a level of 1 nV. Results of preliminary studies of the psychoemotional state of volunteers identified a relationship between signal energies in different amplitude and time intervals in the range from 1 to 650 nV.
