occipital cortex
Học thuậtThân thiện
Definition
Noun: * The occipital cortex is the region of the cerebral cortex located at the rear (posterior) part of each hemisphere of the brain. It is the primary center for processing visual information received from the eyes.
Usage
The term occipital cortex is used in anatomical, neurological, and medical contexts to specifically refer to the brain's visual processing center. * Damage to the occipital cortex can result in various types of visual impairment. * Functional MRI scans showed high activity in the occipital cortex when the subject viewed images. * The occipital cortex is divided into several areas, each specialized for different aspects of vision, like motion or color.
Advanced Usage
- Primary visual cortex (V1): This is a specific, critical area within the occipital cortex that is the first cortical region to receive visual input.
- The primary visual cortex, located in the occipital cortex, is essential for basic visual perception.
- Occipital lobe: While often used interchangeably in non-technical contexts, the occipital lobe is the broader anatomical lobe of the brain that contains the occipital cortex.
- The study focused on the gray matter of the occipital cortex within the occipital lobe.
Variants and Related Words
- Occipital lobe (n): The entire rear lobe of the cerebrum, which contains the occipital cortex.
- Visual cortex (n): A general term for cortical areas involved in vision, primarily located in the occipital cortex.
- Striate cortex (n): Another name for the primary visual cortex (V1), referring to its striped appearance.
Synonyms
- Visual cortex (in a general sense)
- Occipital lobe (in a broad anatomical sense)
Related Phrases
- Occipital cortex activation: Refers to the measurable neural activity in this region during visual tasks.
- The experiment measured occipital cortex activation in response to light patterns.
- Occipital cortex lesion: A pathological term for damage or injury to this brain area.
- A patient with an occipital cortex lesion may experience cortical blindness.
Noun
- that part of the cerebral cortex in either hemisphere of the brain lying in the back of the head
