Quiz 6

Question 1

Brain-imaging studies suggest that the perception of flavor depends on activity in the:

Answer 1

orbitofrontal cortex

Question 2

The common output of sensory transduction in all sensory systems is:

Answer 2

An action potential

Question 3

There are specialized regions of the visual cortex for processing all of these stimuli EXCEPT:

Answer 3

emotion

Question 4

Following an accident, a patient was found to have a lesion in the dorsal stream, specifically in the lateral intraparietal sulcus. What would likely result from the lesion?

Answer 4

difficulty in processing movement due to trouble controlling voluntary eye movements

Question 5

The role of the dorsal stream is:

Answer 5

the visual guidance of movement.

Question 6

Investigation of a patient’s brain after a car accident indicates a lesion within the dorsal stream, yet the patient has no deficit in movement. How is this possible?

Answer 6

The damage is to an area that converts visual information for movement rather than controlling movement directly.

Olfaction and gustation are known as the _____ senses.

Answer 7

chemical

apperceptive agnosia

Answer 8

bilateral lateral occipital lobe damage

Answer 10

bilateral damage below the calcarine fissure at the temporal junction

Question 11

site of damage: visuospatial agnosia

Answer 11

neural relays

Question 14

calcarine sulcus

Question 26

The fMRI data gathered by Wilson and Farah support the idea that object identification and mental rotation mainly involve activity in the:

Answer 26

right hemisphere

Question 27

Blindness of one entire binocular visual field is termed:

Answer 27

homonymous hemianopia

Question 28

The property that sets sensory receptors apart from other cells is their ability to:
