KINES 461 - Visual System

 The blind spot is a location on the retina where:

• Optic nerves separate and exit the eye

• Light can be detected

• There are no photoreceptors

• The optic chiasm is located

 What is the name of the structure where some optic nerves cross to the opposite side of the brain?

• Thalamus

• Optic chiasm

• Lateral geniculate nucleus

• Primary visual cortex

 A baseball batter must process the movement of the ball as it is pitched towards her. Which visual pathway makes this processing possible?

• The lateral geniculate nucleus pathway

• The optic nerve pathway

• Ventral pathway

• Dorsal pathway

 When ganglion cells converge into a large receptive field, the resulting effect on visual acuity is:

• Visual acuity is lower (we see less clearly)

• Visual acuity is higher (we see more clearly)

• Visual acuity is not affected

 The binding problem refers to how our brain:

• Combines information from both visual fields

• Produces different motor commands into a single movement

• Integrates different types of sensory information into a single experience

• Processes visual information in the primary visual cortex
