## TL;DR

Neuroplasticity is the nervous system's capacity to change synaptic strength, circuit organization, and behavior through experience. This repaired version removes unsupported future reviews and keeps the public facts tied to Kandel, Hebb, and Eriksson.

## Core Explanation

The selected claims cover synaptic change, Hebbian association, and one landmark adult hippocampal neurogenesis paper. Broader therapeutic and daily-neuron-count claims need fresher, narrower evidence before being public claims.
