Occipital, temporal and parietal lobes

Question 1

landmarks of lobes

Answer 1

Central Sulcus (c)

Sylvian Fissure (s)

Question 2

occipital lobe

Answer 2

primary visual cortex: V1

• origin of higher visual processing
• majority of V1 is for the central visual field

Question 5

what did David Hubel find about the occipital lobe?

Answer 5

awake cat with an electrode showing the cat a visual stimulus to activate a simple neuron orientation specific

Question 6

receptive field

Answer 6

• The area of sensory processing of which a neuron is active
• If a visual stimulus is in a specific spot on the retina, only the neurons in that area will activate

Question 7

temporal lobe

Answer 7

• Auditory processing
• Visual and knowledge processing to identify visual objects
• Understanding speech

Question 8

parietal lobe

Answer 8

primary sensory cortex (S1)

superior parietal lobe (SPL)

• movement planning
• people with damage to the parietal might not know how to plan and pick up an object

inferior parietal lobe (IPL)

• to monitor feedback to make fine-tune adjustments to make the movements successful

Question 9

visual spatial neglect: alien hand syndrome

Answer 9

• patients asked to copy a drawing forget to draw things in the affected visual field
• patients with visual neglect given prism lenses, after sometime wearing, they can complete the drawings

Question 10

simple and complex neurons

Answer 10

simple cells - orientation specific to activity in its individual receptive field

complex cells - wider range for activation

Question 11

binocular cells

Answer 11

• to percieve depth
• develop from visual stimuli at a critial period of development in an animal (found in primary visual cortex (V1))
