How is the visual pathway from the eyes different from the ears or hands?
each eye is not primarily connected to one hemisphere only instead, each visual half field is projected to the opposite hemisphere so, if an image is seen in the right visual field it would be seen in the left hemisphere and if an image is seen in the left visual field it would be seen in the right hemisphere
A stroke that affects the left visual cortex would lead to?
loss of rihnt visual fields from both eyes
What is contralateral homoymous hemianopia?

Which area is responsible for the head and eye movement in response to visual stimuli?
Frontal Eye Field

Parts of Visual FoxPro
What are the two parts of a sunspot?

What do the elements of visual elements mean?
It means the parts that are visible in other words, the parts you can see. elements = parts visual = seen

Normal vision in both eyes for right half of the visual field absence of vision in both eyes for left half of the visual field?
Normal vision in both eyes results in the right half of the visual field being dominant. The absence of vision in both eyes results in the left half of the visual field being dominant.
If an object is moving to the left at a constant speed and your eyes are rotating to the left at twice the speed how will you see the object?
The object will appear to be moving to the right in your visual field. This is because your visual field is moving to the left faster than the object is moving to the left. What you will see is that the object will appear in your visual field on the left, and the object will move across your visual field to the right.

Composition of an electrormagnetic wave?

Blindness in one-half of the visual field?
hemianopia
