About Us


Principle Investigator

The Shimojo Psychophysics Laboratory is one of the few laboratories on the campus of the California Institute of Technology which exclusively concentrates on the study of perception, cognition, and action in humans. Our lab employs psychophysical paradigms and a variety of recording techniques such as eye-tracking, functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), as well as, brain stimulation techniques such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and recently ultrasound neuromodulation (UNM). We try to bridge the gap between cognitive and neurosciences. We would like to understand how the brain adapts real-world constraints to resolve perceptual ambiguity and to reach ecologically valid, unique solutions. In addition to our continuing interest in surface representation, motion perception, attention, and action, we also focus on crossmodal integration (including VR environments), visual preference/attractiveness decision, social brain, flow and choke in the game-playing brains, individual differences related to “neural, dynamic fingerprint” of the brain.
