SynapticPlasticity

Meaning

Synaptic Plasticity is the fundamental neurobiological property of synapses—the junctions between neurons—to strengthen or weaken over time in response to increases or decreases in their activity. This dynamic, activity-dependent modulation of synaptic efficacy is the cellular mechanism underlying learning, memory formation, and the brain’s remarkable capacity for adaptation throughout the lifespan. Hormones and neurotrophic factors profoundly influence this process, making it a critical target for maintaining cognitive reserve.
