Which neuron type is primarily involved in information processing within the central nervous system?

Interneurons are the cells that do the processing inside the CNS. They stay entirely within the brain and spinal cord, forming networks that receive signals from sensory neurons and other neurons, integrate that information, and then send outputs to motor neurons or to other interneurons. This integrative work—summation, modulation, and routing of signals—underpins how the nervous system interprets sensory input and coordinates responses. Sensory neurons bring information into the CNS, motor neurons carry commands out to effectors, and pyramidal neurons are a cortical neuron type involved in signaling; the functional group dedicated to processing within the CNS is interneurons.
