A

right; left

17
Q

each hemisphere of the cerebral cortex contains 4 lobes. The frontal lobe contains: (5 things)

A

the primary motor cortex, supplementary motor area, premotor cortex, Broca’s area, and prefrontal cortex

18
Q

The _____ is located on the precentral gyrus and is involved in the execution of movement, while the ______ plays a role in the learning of new motor sequences and, in conjunction with the primary motor cortex, prefrontal cortex, inferior parietal cortex, basal ganglia, and cerebellum, mediates motor imagery

A

primary motor cortex; supplementary motor area

19
Q

Damage to specific areas of the prefrontal cortex may produce one of three syndromes: Damage to the dorsolateral area results in dorsal convexity ______ syndrome; damage to the orbitofrontal area produces orbitofrontal disinhibition syndrome, which is also known as ______, and damage to the mediofrontal area produces mesial frontal apathetic syndrome, which is also referred to as ______

A

dysexecutive; pseudopsychopathy; pseudodepression

20
Q

The parietal lobes contain the ______ cortex, which is located on the postcentral gyrus. Damage to this area may cause tactile ______, apraxia, anosognosia, and disturbances in spatial orientation

A

somatosensory; agnosia

21
Q

Lesions in the left parietal lobe may produce ____ syndrome, which involves a combination of finger agnosia, right-left confusion, agraphia, and acalculia

A

Gerstmann’s

22
Q

The temporal lobes contain the ______ cortex and _____ area and are involved in the encoding, retrieval, and storage of long-term _____ memories

A

auditory; Wernicke’s; declarative

23
Q

The occipital lobes contain the ______ cortex, which is responsible for visual perception, recognition, and memory. Damage may produce _____, which is an inability to recognize familiar objects
