Which lobe contains the sensory cortex that processes pain and heat sensations?

The correct answer is the parietal lobe, as this area of the brain contains the somatosensory cortex, which is responsible for processing sensory information related to touch, pain, temperature, and proprioception. The somatosensory cortex lies in the postcentral gyrus, situated just behind the central sulcus. This region organizes sensory input from various parts of the body, allowing for the perception of sensations such as pain and heat.

In contrast, the frontal lobe primarily deals with executive functions, motor control, and speech production; the occipital lobe is foundational for visual processing; and the temporal lobe is mainly involved in auditory processing and memory.
