The somatosensory cortex, located in the parietal lobe, plays a crucial role in interpreting sensory information, such as touch, temperature, and body position. In the somatosensory cortex, neurons are specifically organized: those at the top process sensations from the lower body, while those at the bottom handle sensations from the upper body. For instance, touching the foot activates neurons at the top of the somatosensory cortex, whereas touching the face activates neurons in the lower part. Adjacent to the somatosensory cortex, within the frontal lobes, lies the motor cortex. This area controls movement by sending signals to voluntary muscles through the peripheral nervous system, facilitating coordinated actions. The association cortex is spread across the cerebral cortex, including neurons not involved in sensory or motor function. Instead, these neurons are responsible for higher intellectual functions such as analysis, planning, and decision-making. For example, Broca's area and Wernicke's area, highlight the complexity and specialization of the association cortex in supporting high-level cognitive functions such as language.
