C)Serotonin
D)None of the above

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) is a process in which synaptic connections between neurons are strengthened, resulting in enhanced communication between them. Glutamate is the most abundant excitatory neurotransmitter in the brain, and it plays a key role in LTP by activating N-methyl-D-aspartate (NMDA) receptors and releasing calcium ions, which trigger the signaling pathways that enhance synaptic plasticity. Therefore, glutamate is the neurotransmitter most closely associated with LTP.
