Researchers at the University of Texas at Dallas paired a biophysically realistic computational model with rat behavioral data and found that discrimination accuracy falls off exponentially as the neuronal activation volumes evoked by intracortical microstimulation (ICMS) overlap (R² = 0.88). With minimal overlap, an intersection-over-union below 1%, rats averaged 85% accuracy, while IoU above 20% left them near chance. The work, published in Frontiers in Computational Neuroscience, gives a mechanistic basis for setting electrode spacing in sensory neuroprosthetics.

Daniel Palanker, a Stanford professor and affiliate of the university's Wu Tsai Neurosciences Institute, has won the U.S. Defense Health Agency's Outstanding Research Accomplishment award for the PRIMA retinal implant, designed to restore central vision after photoreceptor loss. A 2-mm chip sits beneath the retina and is driven by infrared light from augmented-reality glasses, converting that light into current that stimulates the next layer of neurons. A 2025 paper in the New England Journal of Medicine reported that the device let legally blind patients with advanced dry age-related macular degeneration read letters and words, and the award recognizes its potential for military personnel with laser-damaged retinas.
