RESEARCH INTERESTS: fMRI Studies of Visual Perception and Memory
I have been using functional Magnetic Resonance Imaging (fMRI) to characterize
the brain structures involved in visual perception, imagery, and memory.
Functional MRI is a technique that permits the localization of regions in the
human brain that are activated during cognition, with fine spatial and temporal
resolutions (millimeters and seconds, respectively). Due to its
non-invasive nature, fMRI is particularly useful for studying the neural basis
of higher cognitive phenomena, like visual imagery, which are not easily
simulated in animal models. I have found that visual representations of faces
and objects in ventral temporal cortex (the so-called “memory storehouse”)
are widely distributed and ‘top-down’ modulated by a cortical
network of parietal and frontal regions. The goal of my new projects is to
understand effective connectivity and experience-dependent changes within these
cortical networks. Specifically, I use faces and paintings as stimuli and
my subjects, healthy normal volunteers, perform various cognitive tasks in the
MR scanner, e.g., they rate facial attractiveness or assess the aesthetic
affect of art compositions.
