Deep groove dividing anterior frontal lobe from more posterior parietal lobe.

• Anterior to central sulcus.
• Contains primary motor cortex.

• Posterior to central sulcus
• Contains primary somatosensory cortex
• Receives sensory information from body

Separates parietal and occipital lobes

Separates frontal and temporal lobes

• An “island” of cortex
• Medial to lateral sulcus

Neurons here are called pyramidal cells because of their shape.

Responsible for coordination of learned movements.

Receives somatic sensory information from receptors for touch, pressure, pain, vibration, taste, or temperature

Monitors activity in primary sensory cortex

Area within insula that receives taste receptor information

Receives olfactory receptor information

• Primary auditory cortex: Monitors auditory (sound) information
• Auditory association area: Monitors sensory activity in auditory cortex and recognizes sounds, such as spoken words

• Primary visual cortex: Receives information from lateral geniculate nuclei
• Visual association area: Monitors activity in visual cortex and interprets results (Example: recognizing “c” “a” “r” together is the word “car”)
