I am interested in using electrical recording and stimulation techniques in behaving primates to study the relative contributions of different visual areas to supporting visual perception.  This work began with the observation that electrical stimulation of early and late visual areas in macaque visual cortex had similar ability to produce a detectable percept (Murphey and Maunsell 2007).  More recently, I have been working with patients with 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.
I am interested in the contributions of electrical signals in the human brain to visual perception.  For my thesis work, I worked with non-human primates as well as with patients with medically intractable epilepsy implanted with semi-chronic subdural surface electrodes for clinical purposes. We used electrical stimulation to examine the role of different visual areas in supporting visual percepts.
 
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.

I am interested in the contributions of electrical signals in the human brain to visual perception. For my thesis work, I worked with non-human primates as well as with patients with medically intractable epilepsy implanted with semi-chronic subdural surface electrodes for clinical purposes.
