What type of neurons are responsible for sending sensory information to the brain?

Afferent neurons are specifically designed to transmit sensory information from the peripheral nervous system to the central nervous system, which includes the brain. These neurons are critical for processing sensory input because they carry signals regarding touch, temperature, pain, and other sensations to the brain for interpretation and response. This function allows the brain to be aware of and react to stimuli from the environment, thereby playing a crucial role in sensory perception.

Motor neurons, on the other hand, transmit signals away from the brain and spinal cord to muscles and glands, facilitating movement and responding to sensory input. Efferent neurons, synonymous with motor neurons, carry information that results in action rather than sensation. Interneurons primarily function as connectors or processors within the central nervous system, relaying signals between afferent and efferent neurons but are not responsible for sending sensory information from the body to the brain. Thus, afferent neurons are the correct choice for relaying sensory information back to the brain for processing.
