Federal Grant Award Summary

The University of Texas at Austin received a $696,503 Project Grant from the National Eye Institute (NEI) under the Vision Research program (CFDA 93.867), effective April 1, 2026 through March 31, 2031. This five-year award supports fundamental neuroscience research examining the cellular and circuit mechanisms underlying invariant visual representations in the brain. Specifically, the project investigates how the visual cortex constructs direction-selective neurons that respond to motion patterns rather than individual stimulus components—a capability essential for scene segmentation and object recognition. The research employs electrophysiological recordings in rodent and primate visual systems to dissect how spatial receptive field properties in the thalamus and primary visual cortex (V1) establish the foundation for pattern motion selectivity, with subsequent computations in higher visual areas generating spatially invariant representations.

The deliverables include empirical findings from comparative neurophysiological studies, mechanistic insights into the feedforward and feedback circuit transformations supporting motion invariance across cortical hierarchies, and characterization of pattern cell properties across multiple mammalian species. These research products advance fundamental understanding of visual system organization and cortical computation, contributing to the NEI's mission of understanding eye and visual system function to support vision research innovation. The work is performed at UT Austin's facility in Austin, Texas.
