D
In the sensory cortex of the brain
Verified step by step guidance1
Begin by understanding the pathway of touch sensation in the human body. Touch receptors in the skin detect stimuli and send signals through sensory neurons.
These signals travel through the peripheral nervous system to the spinal cord, where they are relayed to the brain.
The signals then reach the thalamus, which acts as a relay station, directing sensory information to the appropriate areas of the brain.
The sensory cortex, located in the parietal lobe of the brain, is responsible for processing touch sensations. It interprets the signals received from the thalamus.
Recognize that while the thalamus plays a crucial role in relaying sensory information, the sensory cortex is where the sensation of touch is first processed and interpreted.
