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.

Glutamate Receptors

Receptors located in the nervous system that bind glutamate, the primary excitatory neurotransmitter, and mediate cellular responses.

Acetylcholine Receptors

Proteins found on cell membranes that respond to the neurotransmitter acetylcholine, playing critical roles in the nervous system.
