Lobes of the brain Flashcards
What is the inferior border of the frontal lobe called?
Sylvian fissure (Lateral sulcus)
What are the L & R frontal lobes separated by?
Great longitudinal fissure
damage to the dominant hemisphere (usually left) will result in damage to which area of the frontal lobe?
broca’s area
how does damage to broca’s area present?
motor aphasia (expressive language) - pt can comprehend speech but cannot form language
frontal lobe damage will result in ipsilateral motor deficits - T/F?
F
CONTRALATERAL deficits
frontal lobe damage will result in what kind of symptoms?
personality change
can’t plan things
judgement is skewed
if you have a frontal lobe epilepsy, it causes a focal or generalized seizure?
FOCAL
In frontotemporal dementia the frontal lobe is:
a) atrophied
b) hypertrophied
atrophied
name the 2 cortexes found in the parietal lobe
Somatosensory cortex (post-central gyrus)
Parietal associated cortex (this integrates sensory info)
do you get superior or inferior visual field defects when there is damage to parietal lobe?
INFERIOR
what kind of seizures does the parietal lobe damage cause
sensory seizures
the primary auditory cortex is found in which lobe?
temporal lobe
temporal lobe damage symptoms
‘weird symptoms’
absence seizures
olfactory hallucinations - (related to seizures)
superior visual defects
Wernicke’s aphasia (if dominant hemisphere
