brain lobe function/disorders etc Flashcards
1
Q
frontal lobe divisions
A
primary motor cortex, premotor cortex, prefrontal cortex
2
Q
frontal lobe functions
A
- how we know what we are doing w/in our environment
- controls our emotional response
- assigns meaning to the words we choose
- how we intitiate activity in our environment
- judgements we make about our daily activities
- involves word associations
- memory for habits and motor activities
3
Q
parietal lobe divisions
A
primary somatosensory cortex, posterior parietal cortex, angular gyrus, supramarginal gyrus
4
Q
temporal lobe structures
A
primary auditory cortex (heshl’s gyrus), wernicke’s area, planum temporale
5
Q
parietal lobe disorders
A
- tactile agnosia
- motor apraxia
- alexia
- contralateral neglect
- anomia
- agraphia
- dycalculia
6
Q
primary motor cortex
A
- activating and controlling motor acts
- motor neurons arranged somatotopically
frontal lobe
7
Q
premotor cortex
A
- plans skilled/complex movements
- hand, finger, and speech movements
frontal lobe
8
Q
prefrontal cortex
A
- executive functioning of the brain: reasoning, abstract thinking, pragmatic function, self monitoring, planning, descision making
frontal lobe
9
Q
primary somatosensory cortex
A
- responds to touch/pain stimuli from the whole body
- cells arranged somatotopically
- range from recieving input from brainstem nuclie, to encoding texture and shape of touched objects, to encoding magnitude and direction of touched objects
parietal lobe
10
Q
posterior parietal cortex
A
- contains cell groups that integrate and process different sensory stimuli
- creates complex sensory experiences
- primary analysis in auditory cortex and visuall cortex is sent to the PPC where it’s analyzed more complexly
- association and integration
parietal lobe
11
Q
angular gyrus
A
- lesions here result in higher order language deficits
- understanding metaphor
- understanding mathematical concepts
- mathematical performance
parietal lobe
12
Q
supramarginal gyrus
A
- involved in word meaning
- relation of individual speech sounds to the formation of words
- ability to connect words with action patterns (eg, let me show you how to whistle)
parietal lobe
13
Q
primary auditory cortex
A
- primary signal analysis performed (frequ. duration, intensity)
temporal lobe
14
Q
planum temporale
A
- more complex auditory analysis (speech/language perception/understanding)
- considered auditory association cortex
- left right asymmetry
temporal lobe
15
Q
wernicke’s area
A
- brain region associated with speech/language comprehension
- imaging work of areas surrounding sylvian fissure support this theory
- superior temporal gyrus is highly active when required to make decisions about individual speech sounds
- more widespread regions of the temporal lobe active when required to make descisions about single word meaning, grammatical complexity, and abstract meaning
temporal lobe
