We live in a dynamic visual environment in which we must quickly and accurately interpret the events around us. How do we do it?
The VPNL uses a combination of functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), concurrent TMS and electroencephalography (EEG), and psychophysical techniques to isolate the neural correlates of visual perception.
What we do:
Social actions and intentions
Perception and recognition of actions of others is a complex process. Using psychophysical measures such as face perception, biological motion, and Posner-type cueing tasks we can measure
visual recognition • attention • cognitive control
during social perception.
Functional specialization on the human STS
1) identify the shared, distributed network involved in socially relevant information processing.
2) determine functional relationship among the various cortical regions

Functional connections in the TPJ during temporal selective attention
Perception of natural experiences requires allocation of attention towards features, objects, and events that are moving and changing over time. Using both fMRI functional connectivity methods and psychophysics, we measure the role of attention in discriminating temporal features.
