NEURO 3050 EXAM 3 QUESTIONS AND
ANSWERS 100% CORRECT
phrenology - ANSWER different areas of the brain are responsible for different functions
association areas - ANSWER these are localized areas found in all cortices
prefrontal - ANSWER this part of the association area is made up of the ventromedial
and dorsolateral regions
ventromedial region - ANSWER this region of the prefrontal association area has heavy
interconnections with the limbic system via the dorsomedial thalamic nucleus (aka
emotions)
emotions - ANSWER what does the dorsomedial thalamic nucleus regulate
dorsolateral region - ANSWER this region of the prefrontal association area contains
executive functions such as decision making, planning, insight, foresight, and working
memory
dorsolateral - ANSWER this is one of the last areas of mature during neurodevelopment
,personality, working memory - ANSWER the dorsolateral prefrontal association area
maintains an individuals's _______, _____ _____, and an appreciation of self in the world; the
planning part of this brain changes as people mature
underactive - ANSWER the dorsolateral prefrontal association area is _____ when a person
suffers from chronic schizophrenia, as well as impaired restraint, disordered thoughts,
and inability for appropriate action
lobotomy - ANSWER surgery to disconnect the dorsolateral prefrontal area from brain;
used for severe psychotic depression
emotionally blunted - ANSWER the main side effect of a lobotomy was that people were
_____ _____, meaning spontaneity, responsiveness, and self control were reduced, along
with loss of ambition, etc.
phineas gage - ANSWER a man who had a severe injury through his brain which basically
caused him to have a lobotomy; his personality, reasoning, and capacity to understand
was destroyed (may have had slight recovery though)
parietal association area - ANSWER body image issues stem from this association area,
located caudal to primary sensory cortex
contralateral - ANSWER lesion to the parietal association area results in problems paying
attention to objects on the _______ side of the lesion
, apraxia - ANSWER caused by damage to the left side of the parietal association area or
supplementary area, is the inability to perform purposeful action or an inability to make
proper use of a known object
aphasia - ANSWER language disorders caused by issues to the left side of the parietal
association area; there are several types including Broca's and Wernicke's
neglect syndrome - ANSWER associated with damage to the right side of parietal
association areas, is the inability to attend to objects including one's own body despite
all other senses being intact
sequential motor activity - ANSWER apraxia results in the inability to use an item for the
correct purpose and executing _____ _____ ____ despite having normal muscle function
5 and 7 - ANSWER damage to Broca's areas __ and ___ disrupts the ability to carry out
proper sequence of movements, which typically projects to the prefrontal cortex
egocentric - ANSWER this kind of neglect syndrome (caused by a lesion in the right
parietal association area) is when one half of the visual field is ignored
allocentric - ANSWER this kind of neglect syndrome (caused by a lesion in the right
parietal association area) is when the left side of all objects is ignored
