Final answer:
The postcentral gyrus of the parietal lobe contains the primary somatosensory cortex, responsible for processing tactile sensations and general senses of the body such as proprioception and kinesthesia.
Step-by-step explanation:
The main sensation associated with the parietal lobe is somatosensation, meaning the general sensations associated with the body. Posterior to the central sulcus is the postcentral gyrus, the primary somatosensory cortex, which is identified as Brodmann's areas 1, 2, and 3. All of the tactile senses are processed in this area, including touch, pressure, tickle, pain, itch, and vibration, as well as more general senses of the body such as proprioception and kinesthesia, which are the senses of body position and movement, respectively.
