Geoffrey Ghose

Geoffrey Ghose, PhD is a Professor in the Department of Neuroscience at the University of Minnesota Medical School. His research focuses on understanding the neural mechanisms underlying perception, attention, and sensory processing in the brain. He employs advanced neuroimaging techniques like fMRI and electrophysiological recordings in combination with computational modeling to investigate how sensory information is processed across cortical hierarchies.

Key research themes include the role of alpha oscillations in visual processing, the impact of attention on auditory and visual cortex activity, and the optimization of neuroimaging methodologies. His work bridges basic neuroscience with translational applications in neurotechnology and perceptual learning strategies. He has pioneered techniques for analyzing task-dependent cortical activity profiles and refining fMRI sensitivity without sacrificing spatiotemporal precision.

Recent investigations explore the interplay between top-down microcircuitry and perceptual decision-making, as well as the neurophysiological bases of perceptual ambiguity resolution. His studies utilize both human and non-human primate models, with a particular focus on visual and auditory cortical areas such as V4, MT, and auditory cortex regions. Ghose's contributions have advanced understanding of how neural synchrony and microcircuit dynamics shape sensory perception and cognitive functions.
