Synapses are tiny spaces between neurons; the gap between neurons is referred to as a(n) (neurotic/synaptic) gap.

The correct term to fill in the blank is "synaptic."

Explanation:

Synapses are essential components of the nervous system where communication between neurons occurs. The synaptic gap, also known as the synaptic cleft, is the small space between the presynaptic neuron (the sending neuron) and the postsynaptic neuron (the receiving neuron). When a nerve impulse reaches the end of a neuron (the axon terminal), neurotransmitters are released into the synaptic gap. These chemicals then bind to receptors on the postsynaptic neuron, facilitating the transmission of signals throughout the nervous system. Understanding synapses and their functioning is crucial for comprehending how neurons communicate, which is fundamental to all neurological processes, including reflexes, learning, and memory.
