An axon collateral from one neuron that circles back and synapses with a previous neuron describes
A) a converging circuit.
B) parallel processing.
C) a reverberating circuit.
D) serial processing.

Question

Quizplus · Accepted Answer

A reverberating circuit is a neural circuit in which a single impulse is transmitted back and forth between two or more neurons, causing a prolonged synaptic signal. This back-and-forth signaling is often an important component of rhythmic activities, such as breathing and sleeping, and can also help to maintain a persistent memory or motor activity. The axon collateral looping back to synapse with a previous neuron provides the synapses needed for this type of circuit.
