Brodmanns Areas + Some other things Flashcards
(16 cards)
Brocas aphasia characteristics-
comprehension intact but fluency and repetition not
Wernickes aphasia characteristics-
fluency intact but repetition and comprehension not
Primary motor cortex –> # & if lesion?:
- Precentral gyrus (M1) -4
- contralateral weakness, spastic paralysis, hyperreflexia
premotor and supplementary motor –> # & if lesion?:
- superior and middle frontal gyri (M2) - 6
- apraxia
frontal eye field –> # & if lesion?:
- superior and middle frontal gyri of pre-frontal cortex - 8
- disruption of some of the most complex aspects of behavior
brocas area –> # & if lesion?:
- opercular and triangular parts of inferior frontal gyrus - 44
- nonfluent, motor, expressive - COMPREHENSION INTACT
primary somatosensory cortex –> # & if lesion?:
- post central gyrus - 3,1,2
- loss of tactile discriminatory and proprioception on CONTRALATERAL side - pain not elicited, abolished or relieved
somatosensory association area –> # & if lesion?:
- superior parietal lobule - 5.7
- tactile agnosia, astereognosis, neglect syndrome
primary visual cortex–> # & if lesion?:
- banks of calcarine sulcus (V1) - 17
- initial processing from both eyes gone
cortex surrounding area (vision info from primary vision cortex) –> # & if lesion?:
- cortex surrounding area17 - 18,19
- visual agnosia, achromatopsia, akinetopsia
primary auditory area–> # & if lesion?:
-superior temporal gyrus (A1) - 41 - Granular cortex
auditory association area –> # & if lesion?:
-superior temporal gyrus (A1) - 42
Wernickes area –> # & if lesion?:
- superior temporal gyrus - 39,22
- babbled not coherent speech - FLUENCY INTACT
apraxia
given command and they understand and want to do it but cant execute
aphasia
cant comprehend and formulate language
agnosia
loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not defective nor is there any significant memory loss
