Sirawaj Itthipuripat

Postdoctoral Fellow
Research Area: Cognition and Cognitive Neuroscience
Neuroscience
Quantitative Methods


I study neural mechanisms that support selective attention, learning, and memory in both healthy and clinical populations. I use combinations of neuroscience methods including EEG, fMRI, brain stimulation, psychophysics, and computational models.
