Mar 6, 2024 · Given that the combination of straight lines and curves can give rise to any shape, we hypothesized that the brain encodes the concave and convex curvatures of an environment (for example,...
Mar 6, 2024 · The study titled “Subicular neurons encode concave and convex geometries” is published today online in the journal Nature. The discovery was made possible by extensive and close collaboration among Drs. Yanjun Sun (Stanford), Douglas A. Nitz (UCSD), Xu Xiangmin (UCI) and Lisa Giocomo (Stanford).
Mar 6, 2024 · From left to right, concave, convex and straight environmental features are respectively encoded by corner cells (concave or convex) and boundary vector cells. UC Irvine, Stanford University and UC San Diego team up for breakthrough research in the brain’s spatial mapping system.

Jan 1, 2006 · The stimulus set included convex, concave and outline angles and curves that pointed in one of eight directions at 45° intervals (orientation 45°, 90°, etc.) and subtended one of three angular extents (acuteness: 45°, 90°, 135°). Four edges and lines were also included for a total of 156 stimuli.
