WebDefinition. The neural network that manages a reflex is known as a reflex or simple reflex arc. In vertebrates, most sensory neurons synapse in the spinal cord rather than entering the brain directly. By activating the spinal motor neurons, faster reflex actions can be induced without waiting for signals to travel to the brain. WebFigure 2 Generalized reflex arc. Reaction time is the amount of time required for an individual to perceive and respond to a sensory stimulus (such as the act of swinging a bat at a baseball). The average reaction time for a visual stimulus is 200 to 250 ms; for hearing, 150 to 200 ms; and for touch, 130 to 170 ms.
