Experience strengthens existing synapses when
A) pre- and postsynaptic neurons are simultaneously active.
B) activity of the pre- and postsynaptic neurons are not synchronized.
C) activity in the postsynaptic neuron precedes activity in the presynaptic neuron.
D) the pre- and postsynaptic neurons use the same neurotransmitter substances.

Question

Quizplus · Accepted Answer

When pre- and postsynaptic neurons are simultaneously active, it strengthens existing synapses through a process called long-term potentiation (LTP). LTP involves strengthening the connections between neurons by increasing the release of neurotransmitters, and activating certain cellular and molecular mechanisms that lead to structural changes in synapses that strengthen the connection.
