We use a combination of fMRI, source-imaged EEG, and psychophysics.

 

MRI:

For most standard imaging purposes, such as creating retinotopic maps and generating high-resolution anatomies, we use Stanford's Vistasoft neuroimaging software package. Information about this Matlab-based imaging software can be found here. We scan at the 3T scanner at the NeuroImaging Center at UCSF's main campus


Source-imaged EEG

Souce-imaging EEG uses information based on the retinotpic maps and the high-resolution anatomies obtained from the MR images, as well as computer-generated headmodels which model individual subject's scalp, skull, and head topographies along with their conductance. Inverse models and forward soultions are generated based on this information, using in-house programs and scripts.
