Psychedelic Neuroanatomy: Cerebral Cortex (StatPearls Brief; 2 min)*

I. Introduction to the Cerebral Cortex The cerebral cortex is the outer layer of the brain. It consists primarily of folded gray matter. The folding increases the brain's overall surface area. It is divided into two distinct cerebral hemispheres. It controls sensory, motor, and cognitive functions. II. Development and Embryology It develops from the anterior part of the neural tube. This area is known as the forebrain or prosencephalon. Cortical development begins around the third week. It involves massive neural proliferation and migration. By birth, the brain contains billions of neurons. III. The Frontal Lobe The frontal lobe is the largest lobe in the brain. It handles prospective memory and speech production. Broca's area resides here and aids in spoken speech. The prefrontal cortex regulates human personality. Damage here can cause severe emotional dysregulation. IV. The Parietal Lobe The parietal lobe sits posterior to the frontal lobe. It houses the primary somatosensory cortex. This region processes touch, pain, and temperature. It integrates sensory data with other modalities. The inferior lobule aids in language and math skills. V. The Temporal Lobe The temporal lobe sits below the lateral sulcus. It contains the primary auditory cortex for hearing. Wernicke's area here is critical for speech processing. The medial temporal lobe contains the hippocampus. This region is essential for declarative memory making. VI. The Occipital Lobe The occipital lobe is at the back of the human brain. It is the primary visual processing center. It receives visual signals directly from the retinas. It analyzes color, shape, and object movement. Lesions here can cause partial or complete blindness. VII. Cortical Blood Supply Blood comes from the internal carotid and vertebral arteries. The anterior cerebral artery supplies medial frontal areas. The middle cerebral artery supplies lateral surfaces. The posterior cerebral artery supplies the occipital lobe. Strokes in these arteries cause specific cortical deficits. VIII. Cellular Structure The cortex contains a six-layer structure of neurons. Pyramidal cells are the main excitatory neurons. Glial cells support and protect these neural networks. Astrocytes regulate the extracellular environment. Oligodendrocytes provide myelin for neural axons. IX. Clinical Significance Frontal lesions can cause weakness and personality changes. Parietal lesions can cause apraxia and sensory loss. Temporal lesions may lead to deafness or hallucinations. Occipital lesions lead to visual field deficits. X. Neural Tube Defects Neural tube defects can cause severe brain malformations. These occur early in embryological development. Examples include anencephaly and spina bifida. Anencephaly is a failure of brain and skull formation. Lissencephaly results in a smooth brain surface.
