Organization of the Cerebral Cortex

central sulcus - separates anterior and posterior portions of the cerebral cortex


tends to be motor in function

frontal lobe

precentral gyrus (primary motor cortex) - controls voluntary and delicate movements

prefrontal cortex - involved in acting out of emotions


tends to be sensory in function

parietal lobe

postcentral gyrus (primary sensory cortex) - receives somatosensory and gustatory signals

parieto-occipital sulcus - separates occipital lobe from parietal lobe

occipital lobe - receives visual signals


lateral sulcus - separates temporal lobe from parietal lobe

temporal lobe - receives auditory and olfactory signals

involved in memory and emotion
