Peripheral Nervous

The part of the nervous system outside the brain and spinal cord, which connects the central nervous system to limbs and organs.

Homeostasis

The self-regulating process by which biological systems maintain stability while adjusting to conditions that are optimal for survival.

Long-Term Potentiation

Long-term potentiation is a long-lasting enhancement in signal transmission between two neurons that results from stimulating them synchronously, often studied for its role in learning and memory.

Long-Term Depression

A process of synaptic plasticity where the efficacy of neuronal synapses decreases, often leading to the weakening of specific memory traces.
