DECODING ORIENTATION AND MOTION The Tong Lab has developed novel methods to decode orientation- and direction-selective responses from fMRI activity patterns in the visual cortex. These methods allow us to investigate the neural mechanisms that support conscious perception, attentional selection, and visual working memory.
-
FACE AND OBJECT PROCESSING How are faces and complex objects represented and processed at successive stages of the visual pathway? How are stable or invariant representations achieved, such that a specific item can be robustly identified across a range of viewing conditions?

MECHANISMS OF VISUAL ATTENTION
We are investigating how top-down attention selectively enhances the representation of visual features and complex objects to improve performance at challenging perceptual tasks.
-
VISUAL WORKING MEMORY Our lab is developing fMRI and psychophysical methods to better understand how the brain actively maintains precise information about a remembered stimulus over prolonged delay periods.
-
NEURAL BASES OF VISUAL AWARENESS Our lab uses a variety of visual paradigms, binocular rivalry coupled with fMRI to examine the neural basis of visual awareness. These techniques have helped our lab to elucidate several of the functional regions dedicated to complex object processing.
