A)It refers to increased responsiveness to mild stimuli following a strong or noxious stimulus.

D)It involves transient strengthening of pre-existing synapses.

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) refers to the persistent strengthening of existing synaptic connections in pathways, which leads to an increase in the efficiency and efficacy of synaptic transmission. This occurs as a result of repeated and sustained activation of the synapse, causing changes in the molecular and structural composition of the synapse. This process is believed to underlie certain forms of learning and memory.
