Interneurons are responsible for the distribution of sensory information and the coordination of motor activity. They are also involved with all higher functions, such as memory, planning, and learning. The more complex the response to a given stimulus, the greater the number of interneurons involved. Knowing this, what can you predict about the ratio of interneurons to sensory and motor neurons in the nervous system of higher animals?
A. There must be equal numbers of sensory neurons, motor neurons and interneurons.
B. Since interneurons connect the other two types, it is necessary to have only half as many interneurons as motor and sensory neurons.
C. Interneurons likely outnumber all other types of neurons combined.
D. None of these choices are correct.
C. Interneurons likely outnumber all other types of neurons combined.
