here are neurons that form a chain, or pathway, to relay sensory information from the sensory receptor to the somatosensory cortex of the cerebral cortex.
These neurons are known as relay neurons or second-order neurons. They receive input from the primary sensory neurons at a synapse and then transmit the information to higher brain regions for further processing and integration. The relay neurons are located in specific regions of the central nervous system, such as the thalamus, which serves as a major relay station for sensory information. In the somatosensory pathway, relay neurons play a crucial role in conveying tactile, proprioceptive, and nociceptive signals from the body to the brain, allowing us to perceive and respond to different sensory stimuli.
