ERP Synchronization Device

The stimulus-response synchronization device, also known as the Sync Box, provides split-second accuracy in synchronizing EEG readings to stimulus presentation. Intended for ERP measurements..

By recording of ERP signals a patient reacts to audiovisual stimuli during EEG-measurement, hence the accurate registration of timing synchronization between stimulus presentation and the patients' reactions represents a quality standard for this method. The Sync-box registers both visual and auditory stimuli with the highest timing-accuracy and delivers this information to the EEG-recording system. 

Can only be used in combination with a NeuroAmp II5S

Please inquire for pricing.
