first visual area
Học thuậtThân thiện
Definition
Noun: * Primary Visual Cortex (V1): The first visual area is the region of the cerebral cortex, located in the occipital lobe, that is the initial and primary site for processing visual information received from the eyes. It performs basic interpretation of visual stimuli, such as detecting edges, orientation, and motion.
Usage
The term "first visual area" is a specific anatomical and neuroscientific term. It is used formally in academic, medical, and scientific contexts to describe the brain's primary region for visual processing. * Damage to the first visual area can result in cortical blindness, even if the eyes are healthy. * Neuroscientists study how the first visual area responds to simple shapes and patterns.
Advanced Usage
- "Striate cortex": Another name for the first visual area, referring to its striped appearance (stria of Gennari) visible to the naked eye.
- The striate cortex is another term for the primary visual cortex.
- "Brodmann area 17": A classification of the first visual area based on the cytoarchitectonic map of the brain created by Korbinian Brodmann.
- In Brodmann's classification, the first visual area corresponds to area 17.
Variants and Related Words
- Primary visual cortex (V1): The most common synonym in neuroscience.
- Striate cortex: A histological/anatomical synonym.
- Brodmann area 17: A numerical classification synonym.
- Visual cortex: A broader term that includes the first visual area (V1) as well as secondary visual areas (V2, V3, V4, V5/MT).
Synonyms
- Primary visual cortex
- V1

Related Concepts (Not Phrasal Verbs or Idioms)
- Optic radiation: The neural pathway that carries visual information from the thalamus to the first visual area.
- Lateral geniculate nucleus (LGN): The thalamic structure that sends signals to the first visual area.
- Visual processing: The general function performed by the first visual area and subsequent cortical regions.
Noun
- the part of the occipital cortex that receives the fibers of the optic radiation from the lateral geniculate body and is the primary receptive area for vision
