Long-lasting synaptic changes that lead to learning and memory include long-term potentiation (LTP) and depression (LTD) of brain circuits.The main difference between these two phenomena is
A) the level and frequency of the stimulation to the brain.
B) one results in learning, the other results in memory.
C) they occur in different circuits of the brain.
D) LTP is long-lasting, whereas LTD is temporary.
E) LTD is long-lasting, whereas LTP is temporary.

Question

The main difference between LTP and LTD lies in the level and frequency of the stimulation to the brain. LTP is typically induced by high-frequency stimulation leading to a long-lasting increase in signal transmission between two neurons, while LTD is often induced by low-frequency stimulation, resulting in a long-lasting decrease in signal transmission.
