← Human Body & HealthWhich signal delay results from hypomyelination during development?
A)Reduced saltatory conduction velocity✓
B)Increased glutamate receptor desensitization
C)Enhanced temporal lobe gamma rhythms
D)Decreased cerebellar Purkinje cell firing
💡 Explanation
Hypomyelination impairs the insulating properties in neurons, directly affecting saltatory conduction, because the myelin sheath facilitates rapid action potential propagation. Therefore, reduced conduction velocities results, rather than receptor or distinct brain regions being directly impacted because of myelin.
