Eye Movement
The cranial nerve responsible for moving the eye inward
What is the oculomotor nerve?
The location where fibers carrying information of the outer visual field decussate
What is the optic chiasm?
The pathway that allows you to locate an object or stimuli in space
What is the dorsal or "where" pathway?
The phenomenon where one can still detect aspects of visual stimuli but does not consciously see the stimuli
The cranial nerves implicated in the visual system
What is the CN2 (optic nerve), CN3 (oculomotor nerve) and CN4 (trochlear nerve), C6 (abducens nerve)?
A lesion in this location can cause monocular loss in the right eye
What is the right optic nerve?
The nuclei that projects to the striate cortex via the main visual pathway
What is the lateral geniculate nucleus?
The inability to recognize an object by sight but the ability to copy or draw the object is spared
What is associative visual agnosia?
The area responsible for horizontal saccadic eye movement and visual attention
What is the frontal eye fields?
The visual field deficit caused by macular degeneration
What is a central scotoma?
Projects to the superior colliculus and pulvinar of the thalamus and responsible for unconscious seeing
What is the extrageniculate pathway?
The three key symptoms associated with Balint's syndrome
What is visual simultanagnosia, optic ataxia, and ocular apraxia?
The eye muscle that the abducens nerve innervates
What is the lateral rectus?
Damage to this optic radiation can cause an inferior quadrantanopia or "pie on the floor"
What is Baums loop?
The deficit seen when there is damage to the ventral processing pathway (from V1)
What is object recognition?
Syndrome associated with a lesion to bilateral inferior occipitotemporal cortex
What is prosopagnosia?
Dysfunction in this cranial nerve can cause vertical diplopia
What is the trochlear nerve?
The lesion location for this type of visual deficit
What is the right optic tract?
What is the superior temporal sulcus?
A lesion that corresponds with the qualitative feature of this RCF copy
What is a left parieto-occipital lesion?
