The ERP laboratory at Hampshire currently includes a SynAmps 32 channel amplifier system and two personal computers,
one for stimulus display and behavioral response measurement, and another for data acquisition.
SynAmps is a software-programmable, optically isolated amplifier capable of true DC or AC recording.
It is equipped with 28 monopolar and 4 bipolar channels, and was designed so that the first stage of
amplification takes place in the head box, thereby reducing noise pickup. Impedance and calibration checking
are built into the amplifier and data is transferred to the host computer via a high-speed SCSI connection.
The unit features ultra-low noise amplification and 16-bit analog-to-digital (A-to-D) conversion.
A connector is available for electrode cap arrays. Data acquisition is controlled by SCAN,
a commercially available software suite for electrophysiological data collection and analysis.
SCAN incorporates an intuitive interface for off-line processing and statistics as well as a
variety of off-line processing tools from baseline correction and digital filtering to principal
components analysis and spatial filtering.
