This Project Grant award from the National Eye Institute (CFDA 93.867 - Vision Research) supports research to determine whether micro-stimulation of neurons in the visual cortex can generate perceptions of 3D object shape. The $232,500 award to The Johns Hopkins University will combine electrophysiology, stimulation, and behavioral experiments in macaque monkeys to test the hypothesis that activating neurons in the V4 region encoding 3D geometric shape fragments can bias visual perception. The...
This Project Grant award from the National Institute of Neurological Disorders and Stroke (NINDS), under the Extramural Research Programs in the Neurosciences and Neurological Disorders (CFDA 93.853) federal grant program, will fund the development of a new "mesoscopic electrophysiology" recording system to study brain function in non-human primates. The $606,548 award aims to create two fully functional mesoscopic electrophysiology systems, which will combine the large field of view...

The University of Pittsburgh received a $1,177,273 Project Grant award from the National Institutes of Health (NIH) Office of the Director under the Trans-NIH Research Support program (CFDA 93.310). The award period runs from September 30, 2024 to August 31, 2027.

The funding supports the development of detailed, biologically realistic models to understand and predict how electrical stimulation of the visual cortex evokes perceived patterns of light ("phosphenes") in blind individuals. The project aims to characterize the relationship between patterns of neuronal activation and the perceptual experience of phosphenes, with the goal of enabling reliably interpretable visual prosthetic devices. Key research activities include electrophysiology recordings from a large area of the visual cortex in non-human primates, phosphene localization and matching tasks to assess perceptual characteristics, and the development of computational models linking neural activity to phosphene perception.
