What 40-Hz (gamma) entrainment may tell us about neuroplasticity When people say the brain is “plastic,” they don’t mean soft like clay. They mean changeable —able to strengthen connections, re-route pathways, and learn new patterns. That ability is called neuroplasticity , and it’s the engine behind skill learning, rehabilitation after injury, and even adapting to new routines. Here’s the interesting part: neuroplasticity doesn’t happen randomly. It depends on timing —neuron
