Research Interests
I am interested in the relative contributions of electrical signals in the human brain to visual perception. For my thesis work, I medically intractable epilepsy who are implanted with semi-chronic subdural surface electrodes for clinical purposes to explore the detectability of activation in a functionally identified visual area and the quality of the percept generated with electrical stimulation there.
As a natural extension of the results of this work, I would in the future like to explore (among other things and in no particular order) the effect of training on perception of electrical stimulation in human visual cortex, the relationship between cortical adaptation to sensory stimuli and adaptation to electrical stimulation, the use of electrical stimulation to bias perceptual judgments in primary and extrastriate (especially object selective) cortex, the qualitative mutability of a percept with electrical stimulation using different stimulation parameters, the role of the human frontal eye fields in visual perception, and the effect of behavioral task on the relationship between neuronal activity and choice probability.
