What is the role of the pupil in vision?

Back

The pupil alters the amount of light entering the eye.

Front

What is required for depth perception?

Back

Depth perception requires two slightly different images from each eye.

Front

What is coding in sensory perception?

Back

Coding is the transduction of a stimulus into an action potential that the brain can understand.

Front

What is adaptation in sensory perception?

Back

Adaptation is the ability of a sensory receptor to become less sensitive in the continued presence of a stimulus.

Front

What does a sensory afferent nerve fibre do?

Back

A sensory afferent nerve fibre relays information from the sensory receptor cell to the brain.

Front

What is the function of the retina in vision?

Back

The retina converts light into neural signals and sends them to the brain.

Front

What is the significance of binocular vision?

Back

Binocular vision allows for depth perception by combining images from both eyes.

Front

Define transduction in the context of sensory systems.

Back

Transduction is the process of converting a stimulus into an electrical signal that the nervous system can interpret.

Front

What is the difference between sensation and perception?

Back

Sensation is the detection of stimuli, while perception is the interpretation of those stimuli.

Front

What role do rods and cones play in vision?

Back

Rods are responsible for vision in low light, while cones are responsible for color vision and detail.
