Which of the following is a result of long-term potentiation?
A) The set of receptors on the postsynaptic membrane change, resulting in a stable increase in the size of the postsynaptic potentials at the synapse.
B) The set of receptors on the presynaptic membrane change, resulting in a decrease in the size of the postsynaptic potentials at the synapse.
C) As a result of summation, new synapses form on neurons most involved in storing a memory.
D) The number of types and the relative amounts of neurotransmitters greatly increase at a synapse involved in memory formation.

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) is a process where synaptic connections between neurons become stronger with frequent activation. This strengthening is often due to changes in the number and sensitivity of receptors on the postsynaptic membrane, leading to a stable increase in the size of the postsynaptic potentials at the synapse, which is crucial for memory formation and learning.
