Which of the following is true regarding a system which ours oscillatory responses?

Reverberating or oscillating circuit is a type of neuronal circuit in which the incoming signal travels through a chain of neurons, each of which makes collateral synapses with neurons in a previous pa of the pathway. Positive feedback facilitate oscillatory response by giving a continuous output signal until one neuron in the circuit fails to fire. These circuits may continue for seconds, hours or for lifetime. This circuit is involved in control of rhythmic activities such as sleep wake cycle, breathing and ceain motor activities (arm swinging when walking) and may be involved in sho term memory.
