← Human Body & HealthDuring long-term potentiation within hippocampal neurons during sleep, which consequence follows increased synaptic glutamate release?
A)Reduced AMPA receptor internalization rates
B)Decreased presynaptic vesicle docking
C)Enhanced postsynaptic membrane depolarization✓
D)Inhibition of retrograde endocannabinoid signaling
💡 Explanation
Long-term potentiation (LTP) requires sufficient postsynaptic depolarization to relieve the Mg2+ block on NMDA receptors; because glutamate is the primary excitatory neurotransmitter, increased release enhances depolarization, therefore promoting LTP, rather than reducing AMPA receptor activity or inhibiting retrograde signaling.
