Language and Higher Cortical Functions Flashcards
Role of the frontal lobe
executive function and planning
Role of the parietal lobe
spatial awareness, sensory integration
Role of the temporal lobe
memory and language
Role of the occipitall lobe
visual processing
Parieto-occipitotemporal association area coordinates what
visual, auditory, and body surroundings
angular gyrus interpret what
visually perceived words ( reading)
name object use what area
lateral ant. occipital and post. temporal lobes
Prefrontal association area plans what
complex motor movement
limbic association area locate where
ant. temporal lobe, ventral frontal lobe, cingulate gyrus
limbic association regulate what
behavior, emotions and motivation
key structure of limbic system
hippocampus and amygdala
limbic system do what
emotion express. fight, fleecing, feeding, and fornicationg
symtoms to lesion in limbic system
- Decrease rage and anger responses.
- Impair learning, facial recognition, and cause severe
amnesia when the hippocampi are affected.
inability to recognize face lesion where
medial side of occipital lobes and medioventral side of ventral lobe
what is prosopagnosia
inability to recognize fac
Wernicke’s area do what
interprets the words, determining
thoughts and words to be spoken.
explain language input and output in order
- Reception in the primary auditory area for sound signals
encoding words. - Wernicke’s area interprets the words, determining
thoughts and words to be spoken.
Sign?? - Signals transmitted from Wernicke’s area to Broca’s area via
the arcuate fasciculus. - Broca’s area activates skilled motor programs for word
formation and sends signals to the motor cortex to control
speech muscles.
what is Broca area
activates skilled motor programs for word
formation and sends signals to the motor cortex to control
speech muscles.
damage to wernike area cause what
- Wernicke’s aphasia (receptive aphasia)
- Impaired understanding of spoken and written language.
- Creates meaningless words or nonsensical sentences.
- Speech is fluent but meaningless, with difficulty linking words to ideas.
- Unaware of speech errors.
damage to Broca area cause what
Broca’s aphasia (expressive aphasia)
* Difficulty in forming words, despite understanding language.
* Difficulty expressing oneself fluently due to disrupted grammar and syntax.
* Patients know what they want to say but struggle to speak
conduction aphasia cause from
damage to arcuate fasciculus
global aphasia cause
broca nad wernicke areas affected
what is Wisconsin Card Sorting Task (WCST)
designed to
measure the ability to shift cognitive strategy in response to
changing contingencies.
Test: attentional set shifting, task/rule switching or reversal,
and working memory.
what part promote storage of memory
hippocampus
