Temporal lobe
role in auditory processing, helps with recognising and naming objects, specifically for identifying faces
1 of 20
Agnosia
damage to temporal lobe, aware of object but can't name it
2 of 20
Monkey experiments
max. response to complete face, less response to incomplete faces
3 of 20
Frontal lobe
separated by central sulcus, primary motor cortex stimulation of specific areas, body 'mapped' onto cortex, specific role in personality, planning, social conscience, awareness, many higher functions
4 of 20
Phineas Gage
rod through frontal lobe, changed personality dramatically
5 of 20
Parietal lobe
behind central sulcus, primary somatosensory cortex, stimulation of specific areas, body 'mapped' onto cortex, relates to sensation of touch, larger areas relate to more touch sensitive body regions
6 of 20
Motor and somatosensory homunculi
maps of body projected onto cortex either side of central sulcus, body parts represented by different regions
7 of 20
Somatosensory
relates to sensory (touch) inputs
8 of 20
Motor
relates to movement of these body parts
9 of 20
Contralateral neglect syndrome
damage to right parietal lobe, unable to process sensory information on left side of body, paient asked to copy model picture, neglects stimuli associated with left side of image
10 of 20
Hemisphere asymmetry
certain tasks are mapped to specific hemispheres
11 of 20
Occipital lobe
receives and processes visual information, complex integration creates binocular vision, greater level of detail and depth perception
12 of 20
Association areas
help us understand what we see, concerned with articulating what we see
13 of 20
Loss of motion perception
moving things a series of still images
14 of 20
Cerebrum
specific areas responsible for specific functions
15 of 20
PET scan
positive emission tomography, radioactive substance injected and detected as it passes through brain, allows detection of active areas
16 of 20
Speaking written word
words detected by visual cortex, processed by Wernicke's area, transmitted to Broca's area, stimulates motor cortex to speak word
17 of 20
Speaking a heard word
words detected by auditory cortex, processed by Wernicke's area, transmitted to Broca's area, stimulates motor cortex to speak word
18 of 20
Damage to Wernicke's area
patient cannot understand visual or spoken communication, own spoken communication doesn't make sense, receptive aphasia
19 of 20
Damage to Broca's area
patient can understand visual and spoken communication but cannot produce sensible spoken/written language, expressive aphasia
