This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Introduction to Central Nervous System, Subject name: Physiology
Which one of the following is not an ADVANTAGE of an electrical synapse over a chemical synapse, in the CNS? 
Select and explain. 
A. Narrow time domain, B. Bidirectionality, C. Plasticity, D. No latency
C: Plasticity
Answer: C: Plasticity 
Explanation: The events at the electrical synapses occur in narrow time frame; there is no latency, no synaptic delay, and the conduction is faster, as compared to a chemical synapse. Bidirectionality is a feature of electrical synapse which is not shown by chemical synapse. Plasticity is more marked at the chemical synapses. Amplification of signal, by means such as presynaptic facilitation and divergent synaptic circuits, is a feature of the chemical synapses
