ERP-LAB

"ERP-Light" - P50, P300 and Mismatch Negativity Event Related Potential Testing

SDI’s ERP-LAB offers very targeted testing of P50, P300 and Mismatch Negativity for research involving the pre- and attention-dependent cognitive effects of Alzheimer’s, schizophrenia and other brain abnormalities. The system design includes two channel testing - EEG and EOG (for artifact detection only).The SDI ERP-LAB is a scaled down or “ERP-Light” version of the traditional event related potential test system. The ERP-LAB offers neuropsychiatric researchers interested in testing already-identified landmark areas of the brain a reliable, easy to set up and administer system at a significantly reduced cost. It requires a minimum of four electrodes – one or two on the cheek to record EOG for artifact detection, one behind the ear for grounding purposes and the fourth on the subject’s skull at the Cz location. Audio-Med earphones are used for administering acoustic stimuli.
