The Farivar CCCP lab is focused on the mechanisms of cortico-cortical communication and processing at multiple spatial scales. The figure depicts a visual pattern, a contour, (bottom of the panel) being detected by feature detectors organized in columns of V1. Perception of this pattern is affected by interactions at the inter-columnar (orange), inter-regional (green), and inter-areal levels (purple). Inter-areal communications are critical for complex vision, such as object recognition and scene perception. Injury to a single region disrupts all three interaction types by increasing local inhibition, independent of other factors. The lab is focused on understanding the nature and extent of these interactions for simple and complex visual processing, as well as assessing means of improving these interactions after brain injury to maximize recovery.
The laboratory utilizes advanced methodology, including <1mm resolution functional magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), transcranial magnetic stimulation (TMS), and visual psychophysics.
