Exercise-Induced Neurogenesis: Age-Cohort Model (2D)

This 2D companion to the 3D hippocampal-neurogenesis simulator renders the identical exercise → BDNF → neurogenesis physiology as three linked 2D charts instead of a spatial cell cloud: a live Hill-function dose-response curve tracking your current BDNF level, an age-structured population histogram that shows exactly how many new granule neurons are at each age-in-weeks (immature and mature), and a scrolling time series of hippocampal volume change and spatial-memory score. Because the histogram tracks expected cohort counts directly rather than simulating thousands of individual particles, the underlying survival and maturation dynamics — the same critical window, the same saturating BDNF curve, the same linear volume/memory read-outs from Cotman & Berchtold's and Erickson et al.'s work — are visible as population-level flows rather than as individually blinking spheres.
