Mar 6, 2024 · Spatial firing rate maps of geometric coding cell types in the subiculum of the brain. 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.
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 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 · how the brain encodes environmental corners remains largely unexplored. One brain region that could play a role in encoding environmental corners is the subiculum, a major output structure of 40 the hippocampus that receives highly convergent inputs from both the hippocampal sub-region CA1 and the medial entorhinal cortex (35, 36). Prior work ...

Furthermore, corner cells that encode concave or convex corners generalize their activity such that they respond, respectively, to concave or convex curvatures within an environment. Together, our findings suggest that the subiculum contains the geometric information needed to reconstruct the shape and layout of naturalistic spatial environments.
