• Rods

• Ganglion cells

Which cells participate in lateral inhibition in the retina?

• Bipolar cells

• Photoreceptors

• Horizontal cells

What is the main function of ganglion cells in the retina?

• Release glutamate

• Generate graded potentials

• Generate action potentials

• Receive input from amacrine cells

What is the advantage of lateral inhibition in the visual system?

• Improving depth perception

• Increasing color sensitivity

• Enhancing contrast perception

• Boosting motion detection

What is the function of amacrine cells in the retina?

• Provide lateral inhibition

• Release glutamate

• Enhance visual contrast

Which type of ganglion cells are highly sensitive to low-contrast stimuli and rapid movement visual signals?

• Amacrine cells

• Melanopsin-containing cells

• M cells

• P cells

What is the function of the optic nerve in the visual system?

• Provide lateral inhibition

• Transmit visual signals to the brain

• Enhance color perception

• Generate action potentials

What is the role of the dorsal lateral geniculate nucleus in the thalamus?

• Relay visual information to the visual cortex

• Control skeletal movements

• Relay visual information to the motor cortex

• Process color information

Which area of the cerebral cortex is responsible for receiving sensory information in the visual system?

• Layer II

• Layer I

• Layer III

• Layer IV

What is the phenomenon that allows judging the distances of visual objects based on the nonregister of images on the two retinas?

• Motion detection

• Contrast perception

• Stereopsis

• saccadic movement
