During continuous intense stimulation, the depletion of neurotransmitter stores in the presynaptic terminal leads to

A. Synaptic facilitation
B. Synaptic fatigue
✓
C. Spatial summation
D. Synaptic potentiation

📝 Explanation

Synaptic fatigue occurs when the rate of neurotransmitter release exceeds the rate of its synthesis and recycling, causing a temporary failure of synaptic transmission despite incoming action potentials.
