Siemens Allegra 3T MRI
-
Two 64-channel
high-resolution EEG acquisition systems are available for
psychophysiological research.
o One is a 64 channel Neuroscan
system- SCAN 4.3 with STIM2 for stimulus presentation.
o The other is an Isolated Bioelctric amplifier system custom designed
and built for research at the IOL with 64 channel EEG caps from
Electro-Cap International, Inc.
Using VAPP for auditory and
visual stimulus presentation.

Polhemus 3D
FASTRAK digitizer (magnetically based recording system) is used for
exact localization of electrodes with reference to individual subject
anatomy for subsequent coregistration with anatomical MRI.

Eyelink II – Head
Mounted System: The EyeLink II is a head mounted binocular eye tracking
device with dual image processing modes of pupil only, 500 Hz sampling,
or pupil-CR, 250 hz sampling. The head mounted design makes this high
end system extremely versatile with integrated head movement
compensation and an optional scene camera option.
