What distinguishes electrical synapses from chemical synapses in neuronal communication within the cerebral cortex?

A)Bidirectional ion flow inefficiency
B)Higher action potential propagation speeds
C)Gap junctions enabling direct depolarization
D)Exclusive reliance on glutamate receptors

💡 Explanation

Electrical synapses utilize gap junctions for direct ion flow, enabling faster and bidirectional communication because action potentials propagate through these channels. Therefore, direct depolarization via gap junctions is the key distinction, rather than the slower neurotransmitter-mediated process of chemical synapses.
