128 Channel Electroencephalography System

The clinic electrophysiology studies are involved in the evolution of electrophysiological mechanisms of human brain. EEG and ERP systems are used to understand electro-neurophysiological mechanisms of various neurological disease (i.e., Parkinson’s and Alzheimer’s diseases), sleep disorders and comatose states.
