Which of these statements correctly describes long-term potentiation?
A)It refers to increased responsiveness to mild stimuli following a strong or noxious stimulus.
B)It refers to an increase in strength of existing synaptic connections in pathways involved in initial storage of declarative information following brief periods of stimulation.
C) It involves decreased neurotransmitter release from the presynaptic cells
D) It involves transient strengthening of pre-existing synapses.

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) involves an increase in the strength and efficacy of existing synaptic connections in pathways involved in the initial storage of declarative information. This occurs following brief periods of stimulation, such as a high-frequency train of action potentials. LTP is an important mechanism of synaptic plasticity and is thought to play a key role in learning and memory. The other statements do not accurately describe LTP.
