Shared Electrophysiology Facilities
The Clinical and Translational Research Support Core offers equipment and training to facilitate the use of electrophysiological recording techniques in IDDRC service-eligible cognitive neuroscience projects.
Equipment includes three facilities specifically designed for the recording of event-related potentials (ERPs), and one for the recording of steady-state visual evoked potentials (VEPs).
Neuroscan System. EEG is amplified by Grass AC amplifiers. The amplified signal is exported to a Dell Optiplex Gs+ Pentium computer, where the data are digitized and stored on-line via Scan 4.0. The EEG is recorded with an electrode net, a web of 19 Ag/AgCl electrodes that approximate the International 10/20 system.
The Perceptual Development Laboratory is outfitted with a double-walled electrically isolated sound attenuating booth, a 32-channel custom-built EEG data acquisition system, and two analysis workstations. The laboratory has nine Electrocaps (ElectroCap International) with custom electrode montages in infant through adult sizes.
The Mobile EEG System contains 64 channels housed in a 14-pound box, three laptops for data acquisition, stimulus presentation, and data analysis, and six sensor nets of various sizes. All components have their own Pelican boxes to optimize storage and transport.
The Steady-state VEP Laboratory uses Grass amplifiers with individual gold-plated cup electrodes. Data acquisition and stimulus presentation are performed with desktop computers. Visual stimuli are presented on a Richardson Electronics monitor. The steady-state VEP can be used to evaluate visual acuity as well as cortical processing.
