Study Notes
Occipital Lobe Overview
- Located at the posterior part of the cerebral cortex.
- Plays a crucial role in the processing of visual information.
Visual Cortex Components
- Primary Visual Area (Area 17): Responsible for the perception of visual impulses.
- Visual Association Area (Area 18): Involved in the interpretation and integration of visual stimuli.
- Occipital Eye Field (Area 19): Associated with the movement of the eyes.
Connections
- Receives afferent fibers from the lateral geniculate body, which relays visual information.
- Sends efferent signals to the superior colliculus and the lateral geniculate body, facilitating visual processing.
Functions of Visual Cortex
- Primary Visual Area: Critical for the recognition of visual stimuli.
- Visual Association Area: Enhances understanding and interpretation of what is seen.
- Occipital Eye Field: Coordinates eye movement to track and focus on visual inputs.
