Definition
- Noun:
- Primary visual cortex: The
striate cortexis a region of the brain located in the occipital lobe. It is the first cortical area to receive and process visual information relayed from the eyes via the thalamus. Its name derives from the distinctive striped (striated) appearance it has under a microscope.
Usage
- The is fundamental for basic visual perception, including the detection of lines, edges, and orientation.
- Damage to the typically results in a loss of conscious vision in the corresponding part of the visual field.
Examples
- Noun:
- Neurons in the
striate cortexrespond to specific features like the angle of a line. - Functional MRI scans show high activity in the
striate cortexwhen a person looks at a simple pattern.
Advanced Usage
- "Activation of the striate cortex": Refers to the measurable neural activity in this region when visual stimuli are presented.
- The experiment measured the activation of the
striate cortexin response to moving dots.
