cerebral cortex

Thân thiện

The diagram shows the cerebral cortex of the human brain.

Definition

1. Noun:
   • The outer layer of neural tissue of the cerebrum: The cerebral cortex is the intricate, folded outer layer of the brain's cerebrum, composed primarily of grey matter (neuron cell bodies). It is crucial for higher-order brain functions such as thought, perception, memory, language, and consciousness.

Usage Examples

• Noun:
  • Damage to the cerebral cortex can result in significant cognitive impairments.
  • The human cerebral cortex is highly convoluted, which increases its surface area.
  • Neuroscientists study the cerebral cortex to understand how we process sensory information.

Advanced Usage

• "Cortical" (adj): Pertaining to the cerebral cortex.
  • The study focused on cortical thickness in different brain regions.
• "Neocortex" (n): Refers to the phylogenetically newer part of the cerebral cortex, involved in higher functions.
  • The neocortex is particularly developed in mammals.

Variants and Related Words

• Cortex (n): The outer layer of an organ. When used alone in neuroscience, it often implies the cerebral cortex.
  • The renal cortex is the outer part of the kidney.
• Grey matter (n): A term for areas of the central nervous system rich in neuron cell bodies, such as the cerebral cortex.
• Pallium (n): An anatomical term synonymous with the cerebral cortex.

Synonyms

• Brain cortex
• Cerebral mantle (a less common term)

Related Phrases

• Cortical area: A specific region of the cerebral cortex with a distinct function (e.g., visual cortex, motor cortex).
  • The primary visual cortex is located in the occipital lobe.
• Cortical folding / Gyrification: The process of forming the characteristic folds (gyri) and grooves (sulci) of the cerebral cortex.
