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, corners ...
Mar 6, 2024 · Earlier work has demonstrated that neurons in the subiculum encode the locations of environmental boundaries and objects in an allocentric reference frame, as well as the axis of travel in multi-path environments 25, 33 – 35. Here, we describe single-cell neural representations for concave and convex environmental corners and curvatures in ...

Mar 6, 2024 · A research team co-led by the University of California, Irvine, Stanford University and the University of California, San Diego has discovered that there are special neurons dedicated to representing the convex and concave features of environments (commonly referred to as “corners”) in their study of the brain’s spatial mapping system.
Mar 6, 2024 · The color scale codes the level of neural firing activity (red for high, blue for low). From left to right, concave, convex and straight environmental features are respectively encoded by corner cells (concave or convex) and boundary vector cells. Irvine, Calif., March. 06, 2024 — A research team co-led by the University of California, Irvine ...
Mar 6, 2024 · brain encodes the concave and conve x curvatures of an environment (for example, corners and curved protrusions), in addition to straight boundaries 24 , 25 , 29 .
Mar 14, 2024 · The encoding of the cells also generalizes to other concave curvatures in the environment, such as high-concavity regions of an oval arena. Next, the authors asked whether subiculum neurons also ...

May 7, 2023 · A separate population of subicular neurons encoded convex corners. Both concave and convex corner cells were non-overlapping with subicular neurons that encoded environmental boundaries, suggesting that the subiculum contains the geometric information needed to re-construct the shape and layout of naturalistic spatial environments.
