How Does the Brain Process Visual Information?

What type of cells in the retina are responsible for night vision?

• Bipolar cells

• Rods

• Cones

• Ganglion cells

Which part of the brain controls pupillary size in response to light intensity?

• Superior colliculus

• Primary visual cortex

• Pretectum

• Thalamus

What is responsible for moving the eyes in short jumps, called saccades?

• Primary visual cortex

• Thalamus

• Pretectum

• Superior colliculus

Which part of the brain separates retinal inputs into parallel streams, one containing color and fine structure, and the other containing contrast and motion?

• Lateral geniculate nucleus

• Primary visual cortex

• Thalamus

• Superior colliculus

What is the function of the cells in the magnocellular layers of the lateral geniculate nucleus?

• Contrast and motion processing

• Color and fine structure processing

• Pupillary size control

• Saccadic eye movement

What allows the visual system to calculate where objects are in space in the primary visual cortex?

• Ocular dominance columns

• Color constancy

• Retinotopical organization

• Orientation columns

What is responsible for detecting the edges of objects in the visual world in the primary visual cortex?

• Retinotopically organization

• Ocular dominance columns

• Color constancy

• Orientation columns

What is largely responsible for the phenomenon of color constancy?

• Thalamus

• Primary visual cortex

• Secondary visual cortex

• Pretectum

What is the characteristic of higher order features of vision in the brain?

• Influenced by expectations based on past experience

• Influenced by pupillary size

• Influenced by light intensity

• Influenced by saccadic eye movement

What is the process that occurs in many areas throughout the cerebral cortex based on visual experience?

• Refinement

• Overgrowth

• Pruning

• Hypertrophy
