Cortical Feedback Loops Slash Neural Variability by 93% to Keep Vision Stable
DrKavner · x · 2026-10-02
A computational neuroscience study shows two intrinsic feedback loops in primary visual cortex — fast inhibition and slow homeostatic regulation — cut neural variability from 0.325 to 0.024 (93%) while preserving flexibility. A minimal three-population 'E-I-M' rate model reproduced primate V1 behavior, with virtual neurons matching macaque orientation selectivity benchmarks (0.31–0.38), offering a framework for how vision stays stable near the edge of chaos.
