Question
What is the primary location of the somatosensory cortex?
- a) Frontal lobe
- b) Parietal lobe
- c) Temporal lobe
- d) Occipital lobe
- e) Cingulate cortex
Solution
The primary location of the somatosensory cortex is in the parietal lobe.
Explanation:
The somatosensory cortex is a critical region of the brain responsible for processing sensory information from the body, including touch, temperature, pain, and proprioception (the sense of body position). It is located in a part of the parietal lobe known as the postcentral gyrus, which is situated just behind the central sulcus. This area is organized in a functional manner, representing different parts of the body, with each area being sensitive to stimuli from specific body parts, which is often depicted in a homunculus diagram.
The other options listed (frontal lobe, temporal lobe, occipital lobe, and cingulate cortex) have different primary functions, such as reasoning, hearing, vision, and emotion regulation. Thus, the correct answer is b) Parietal lobe.
