Brain Hierarchy

Question 1

(1) Cerebral Cortex & (4) lobes

Answer 1

• frontal lobe (primary motor cortex)
• temporal lobe (primary auditory cortex)
• occipital lobe (primary visual cortex)
• parietal lobe ( primary somatosensory cortex)

Question 2

Primary Cortex

Answer 2

• primary SENSORY cortices are 1st regions of the cerebral cortex to receive modality-specific sensory info.
• primary MOTOR cortex is last region of cerebral cortex to send info to limbs for execution of voluntary movements
• organization is contralateral

Question 3

Secondary Cortex

Answer 3

• receives modality-specific input directly from primary SENSORY cortical regions
• secondary MOTOR cortex transmits info directly TO primary motor cortex

Question 4

Association Cortex

Answer 4

• outside primary and secondary cortex

* least specialized cortex (not modality-specific) making it hard to pinpoint behavior

Question 5

Identifying regions of Cerebral Cortex

Answer 5

1. by its given name
2. by its location w/in lobes of the brain
3. Brodmann area number
