Final answer:
Interneurons are primarily found in the central nervous system (CNS) and play a role in transmitting signals between sensory and motor neurons. They help in processing and interpreting information within the CNS.
Step-by-step explanation:
Interneurons are primarily found in the central nervous system (CNS). The CNS is composed of the brain and spinal cord, and it is responsible for processing and coordinating information in the body. Interneurons are a type of neuron that transmit signals between sensory neurons and motor neurons within the CNS. They help integrate and interpret information, allowing for complex responses to stimuli.
