Study Arms (2)

Healthy Volunteer Subjects (HV)

Male and female subjects 21-50 years of age, who are in good and stable health with no history or evidence of clinically relevant medical or neuropsychiatric illness. Healthy Volunteer Subjects will undergo Event-Related Potential (ERP)/electroencephalogram (EEG) testing with the COGNISION® System.

Device: Event-Related Potentials (ERP) and Electroencephalogram (EEG) testing with the COGNISION® System

Subjects with Schizophrenia (SZ)

Otherwise healthy male and female subjects 21-50 years of age, who have a current diagnosis of Schizophrenia with a duration of illness greater than or equal to one year. Subjects with Schizophrenia (SZ) will undergo Event-Related Potential (ERP)/electroencephalogram (EEG) testing with the COGNISION® System.

Device: Event-Related Potentials (ERP) and Electroencephalogram (EEG) testing with the COGNISION® System

Interventions

The testing protocol consists of an auditory oddball Event-Related Potential (ERP) paradigm, 40Hz ASSR, and the collection of 6 minutes of resting electroencephalogram (EEG). During the ERP paradigm a variety of auditory stimuli are played through the system's earphones while voltage potentials are recorded from the subject's scalp. At the end of the ERP session, 6 minutes of EEG data will be recorded while the subject is resting. The entire procedure, including set up, instructions to the subject and actual test is expected to take 60-75 minutes.
