← Human Body & HealthWhich clinical effect arises from impaired synaptic glutamate reuptake?
A)Excitotoxicity due to prolonged receptor activation✓
B)Enhanced plasticity from NMDA receptor potentiation
C)Weakened analgesia via decreased substance P
D)Parkinsonism via reduced dopamine synthesis
💡 Explanation
Impaired glutamate reuptake causes excitotoxicity primarily because excessive glutamate lingers in the synaptic cleft, leading to overstimulation of postsynaptic receptors; therefore leading to neuronal damage rather than controlled plasticity under normal physiological glutamate buffering.
