Visuospatial/Visuoconstructional

Question 1

Hemi-inattention vs Hemi-neglect

Answer 1

-Inattention: one modality
-Neglect: two+ sensory modalities

Question 2

Hemi-spatial Neglect Location

Answer 2

Right parietal lobe

Though can be left too technically

Question 3

Hemianopsia

Answer 3

Loss of field of vision in one hemispace

Question 4

What, where

Homonymous Hemianopsia

Answer 4

-Absence of vision in one half of the same visual field in both eyes
-Contralateral lesion after optic chiasm

Question 5

Visual Pathway

Ventral Stream

Answer 5

“What” stream; recognizes object

Question 6

Visual Pathway

Dorsal Stream

Answer 6

“Where” stream; processes where things are in space

Question 7

Location of lesion results in:

Complete blindness in one eye

Answer 7

Before optic chiasm

Question 8

Location of lesion results in:

Bitemporal Hemianopsia

Loss of vision of outer hemispaces in both eyes (can only see middle)

Answer 8

Medial optic chiasm

Question 9

What, where

Cortical Blindness

Answer 9

-No conscious awareness of vision in damaged visual field
-May have some processes (identifying a light or “guess” a facial expression without IDing the person)
-Bilateral occipital lobe damage

Question 10

What, where

Balint’s Syndrome

Answer 10

1. Optic ataxia: inability to coordinate reaching for an object
2. Ocular apraxia: inability to voluntarily shift eye gaze
3. Simultanagnosia: difficulty perceiving more than one object at a time; trouble understanding a scene/big picture

-Bilateral parieto-occipital damage

Question 11

Anton’s Syndrome

Answer 11

Denial of cortical blindness
