The visual pathway 2

Homonymous hemianopia is the loss of the same side of the visual field of both eyes, as occurs in some strokes. Thus, the person would not be able to see things past the middle of the visual field on either the right or left side, depending on the site of the stroke. Such individuals should be carefully attended and warned of objects in the non-functional side of the visual field. Their food and personal objects should always be placed on their functional side, or they might miss them. Hemianopia can be caused by the damage of which part?

• Optic chiasma

• Visual cortex

• Retina

The area which the optic nerve in each eye will cross over.

• Optic radiation

• Geniculate Nucleus

• Primary visual cortex

• Optic chiasm

The first major stop for visual information before being sent to the primary visual cortex.

• Superior Colliculus

• Hypothalamus

• Pretectum

• Lateral Geniculate Nucleus

Area responsible for orientating the head and eyes towards visual cues.

• Sclera

• Striate Cortex

• Retino-hypothalamix Pathway

• Superior Colliculus

The part of the visual field observed with both eyes.

• Lateral Field

• Dual Vision

• Binocular Field

• Monocular Field

The part of visual field closest to the nose

• Inferior

• Nasal

• Temporal

• Superior

Vision where only information from one eye is present.

• Monocular Vision

• Pirate Vision

• Binocular Vision

• Singular Vision

The pathway that plays an important role in object recognition.

• Optic Radiation

• Ventral Pathway

• V1 Pathway

• Dorsal Pathway

The pathway that plays an important role in spatial vision.

• Optic Radiation

• Ventral Pathway

• The Optic Tract

• Dorsal Pathway

What happens to the 10% of the visual data that does not go to the primary visual cortex?

• It is destroyed.

• It travels the cortical visual pathway through the thalamus

• It travels along one of the subcortical visual pathways to the superior colliculus.

• It reflects back out of the retina
