The student studies a diagram of the parietal cortex in her textbook.

Definition
  1. Noun:
    • A region of the cerebral cortex: The "parietal cortex" is the part of the cerebral cortex in each brain hemisphere that is situated beneath the crown of the head.
    • A functional brain area: It is involved in processing sensory information, spatial awareness, navigation, and integrating information from different senses.
Usage Examples
  • Noun:
    • Damage to the parietal cortex can result in difficulties with spatial reasoning.
    • The study focused on neural activity in the parietal cortex during the navigation task.
    • Sensory signals from touch are processed in the parietal cortex.
Advanced Usage

  • "Parietal cortex activation": Refers to the measurable neural activity in this brain region during specific cognitive or sensory tasks.

    • The experiment showed significant parietal cortex activation during the mental rotation exercise.

  • "Posterior parietal cortex": A specific sub-region at the back of the parietal lobe, crucial for planning movements and spatial attention.

    • The posterior parietal cortex is essential for coordinating eye movements and reaching.
Variants and Related Words

  • Parietal lobe (n): The larger anatomical lobe of the brain that contains the parietal cortex.

    • The parietal lobe is divided into several functional areas.

  • Somatosensory cortex (n): A major region within the parietal cortex specifically dedicated to processing touch sensations.

    • The somatosensory cortex maps tactile information from the entire body.
Synonyms
  • Parietal lobe: Often used interchangeably in general contexts, though "cortex" specifically refers to the outer layer of grey matter.
  • Somatosensory cortex: A primary functional component of the parietal cortex.
Related Terms (Conceptual)

  • Spatial neglect: A neurological condition often associated with damage to the right parietal cortex, where a patient fails to attend to one side of space.

    • Spatial neglect is a common consequence of a stroke affecting the parietal cortex.

  • Sensory integration: A key function of the parietal cortex, combining information from vision, touch, and proprioception.

    • The parietal cortex is a hub for multisensory integration.
