1) parallel-after-discharge

Explanation:

Neural circuits are defined as the connections between neurons. These neural circuits are of four types:

Diverging circuits, found in sensory and motor neurons, diverge a single nerve impulse to multiple neurons in the circuit, amplifying the original signal. Convergent circuits, also found in sensory and motor pathways, converge multiple nerve impulses into a single one. These pathways are predominantly involved in inhibition and stimulation. Reverberating circuits, involved in control of sleep-wake cycle and breathing, consist of a neuron chain along which the impulse travels. Parallel after discharge, involved in cognition and mental processing, are a combination of convergent and divergent circuits. They result in an output impulse that lasts at least 15 m/s after the input impulse ends.
