Superior visual field
What separates the parietal lobe from the occipital lobe?
Parieto-occipital sulcus
Define homonymous
The same part of the visual field in both eyes
What is the function of the cones of the retina?
Receive colors and acuity/vision in bright light
What are smooth pursuits of the eye?
Visual tracking, keeping an object’s image on the fovea
Where does the superior bank of calcarine sulcus receive input from?
Inferior visual field
The temporal lobe assists in what type of vision interpretation?
Object recognition
Define hemianopsia
Without vision in ½ the visual field
What is the sclera of the eye?
White outer layer of the eye
What are convergence movements of the eye?
Both eyes adducting to focus on an object coming close
The posterior calcarine sulcus receives input from where?

Both eyes abducting to focus on object moving away
The anterior calcarine sulcus receives input from where?
Peripheral vision
