Sensory neurons carry information from receptors located throughout the body to the brain. Information from both the internal (inside the body) and external environments, in the form of light, heat, pressure, taste, and smell is detected by sensory neurons.
Motor neurons carry impulses from the brain to the body. Movement of muscles and secretion of glands is controlled by motor neurons.
Interneurons reside within the brain and spinal cord and form connections between motor and sensory neurons. Incoming sensory information is transmitted via association neurons to motor neurons which initiate a response.
Interneurons help to form networks, neurons that work together to control complex functions such as learning, remembering, making decisions and other complex behaviors.
