Identify the Brodmann’s areas for the frontal lobe

4 - Primary motor cortex

6 - Premotor cortex

8 - Frontal eye field

6 & 8 = Supplemental Motor

6, 8, 45 = Prefrontal/frontal association cortex

44/45- Broca’s Area

Identify the Brodmann’s Area for the parietal lobe

3,1,2 - Primary Somatosensory Cortex

40 - Secondary Somatosensory

7, 5, 39, 40 - Pariental Association

Identify the Brodmann’s Area for the Occipital Lobe

17 - Primary visual cortex

18, 19 - Visual Association Area

Identify the Brodmann’s Areas for the Temporal Lobe

41, 42 - Primary hearing cortex

22 - Auditory Association Area (Winerkies)

21, 20, 37 - Areas associated w/higher emotions and higher mental function

Name the associated functional deficits that may occur with a CVA impacting the Brodmann’s areas listed above.

If a CVA occurred that impacted the areas above I would expect to see difficulty with speech production (44,45), language comprehension (22), vision (17), and eye movement (8)
