Brain And NS 4 Flashcards
(15 cards)
Temporal lobe
Role in auditory processing, helps with recognising and naming objects, damage leads to agnosia
Frontal lobe
Specific role in personality, planning, social consciousness, and awareness
Primary motor cortex
Located in front of central sulcus, stimulation of specific areas causes specific muscles to contract
Parietal lobe
In charge of responding to and interpreting complex stimuli, damage causes contralateral neglect (left side)
Primary somatosensory cortex
Stimulation of specific areas causes localised sensation in specific areas of the body
Occipital lobe
Receives and processes visual information, damage can cause loss of motion perception
Contralateral neglect
When a patient neglects stimuli from the left side of their vision, and are unable to realise this. If pointed out, they can correct their mistake
The left side of the brain controls…
Reasoning, data, linguistic analysis, numerical analysis
The right side of the brain controls…
Spatial perception and artistic tasks
PET scanning
Position emission tomography, when a radioactive substance is injected and detected as it passes through the brain
Language processing fora written word
Word detected by visual cortex, processed by Wernicke’s area, transmitted to Broca’s area, stimulates motor cortex to speak the word
Language processing of heard words
Words detected by auditory cortex, processed by Wernicke’s area, transmitted to Broca’s area, stimulates motor cortex to speak the words
Damage to Wernicke’s area
Cannot understand visual or spoken information, own spoken communication doesn’t make sense (receptive aphasia)
Damage to Broca’s area
Cannot produce sensible spoken or written language (expressive aphasia)
