Cognition Flashcards
what is cognition
mental action/process of acquiring knowledge and understanding through thought, experience and the senses
functions of the frontal lobe
voluntary movement reasoning executive function personality inhibition + initiative expressive language
how can the frontal lobe be tested
verbal fluency – as many words beginning with ‘F’ in 60 seconds
- cognitive estimates
- proverb interpretation
- primitive reflexes
functions of the parietal lobe
knowing right from left reading + writing body orientation calculation graphaethesia
what would a dominant hemisphere parietal lobe lesion cause
dysphasia dyscalculia dyslexia apraxia agnosia gerstmann syndrome
what is apraxia
inability to perform complex movements in the presence of normal motor, sensory and cerebellar function
what is tactile agnosia
inability to recognise objects through touch
what is Gerstmann syndrome
characterised by
- acalculia - difficulty with simple maths
- agraphia
- finger anomia - loss of ability to distinguish, recognise and name the fingers
- difficulty differentiating right and left
functions of the temporal lobe
understanding speech memory hearing emotions sense of identity
function of the occipital lobe
vision
what lobe of the brain controls voluntary movement
frontal lobe
what lobe of the brain controls body orientation + knowing right from left
parietal lobe
what lobe of the brain controls memory
temporal lobe
what lobe of the brain controls emotions + sense of identity
temporal lobe
what lobe of the brain controls reading + writing
parietal lobe
what lobe of the brain controls reasoning, executive functioning, inhibition + initiate
frontal lobe
what lobe controls expressive language
frontal lobe
where is Brocca’s area found
frontal lobe
dysfunction in which area of which lobe causes expressive aphasia
Broccas area of frontal lobe
what lobe controls understanding of speech
temporal lobe
where is wernicke area found
temporal lobe
dysfunction in which area of which lobe causes receptive aphasia
wernicke’s area of temporal lobe
what is the function of the limbic system
role in emotional experience + visceral regulation
components of the limbic system
hypothalamus amydgala hippocampus dentate gyrus cingulate gyrus
function of hippocampus
to form new memories
spatial memory
navigation memory
function of amygdala
emotional filter
right side = negative emotions (fear/sadness)
left side = pleasant + unpleasant + reward system
which are has strongest association with addiction
septal area
role of hypothalamus in the limbic system
autonomic response to emotional pain
