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?
