How do sensory receptors communicate with the brain?

Sensory receptors communicate with the brain by sending electrical impulses, which are vital for transmitting information regarding various stimuli, such as touch, sound, light, and temperature. When a sensory receptor is activated by a specific stimulus, it undergoes a change that generates an electrical signal, often referred to as an action potential. This electrical signal travels along the axons of sensory neurons towards the central nervous system, specifically to the brain, where it is processed and interpreted.

This process enables the brain to recognize and respond to different sensory inputs, helping individuals perceive their environment. The speed and efficiency of electrical impulses are essential in enabling quick reactions and adaptations to stimuli, thereby playing a crucial role in coordinating responses to the surrounding environment.
