Q

mind-body problem

A

involves questions between brain activity and conscious experience; relation between what our brain does and our awareness of our own existence and our internal and external enviros
Theory
-dualism- the mind and body are separate but connected

Q

forebrain location and function

A
  • largest and most prominent part of the brain. located above the midbrain and extends across the top of the brain
  • regulates complex cognitive processes such as thinking, learning, memory and perception as well as various aspects of emotion and personality

Q

reticular formation function

A
  • Helps screen incoming info so as not to overload the brain
  • alerts higher brain areas to important info
  • maintains consciousness
  • regulates arousal and muscle tension

Q

hypothalamus function

A
  • vital role in maintaining the body’s internal environment

16
Q

Cortical lobes of cerebral cortex

A
  • Frontal lobe- primary motor cortex
  • parietal lobe- primary somatosensory cortex
  • occipital lobe- primary visual cortex
  • temporal lobe- primary auditory cortex
17
Q

roles of cerebral cortex

A

-cerebral hemisphere
- hemispheric specialisation

18
Q

what are the cerebral hemispheres

A

are two almost symmetrical brain areas running from the front to the back of the brain
referred to as left and right side of brain. both sides usually act together in co-ordinate and interactive way

19
Q

left hemisphere specialisation

A
  • receive and process sensations from right side of body
    -control voluntary movements on the right side of the body
  • verbal tasks (reading, writing)
  • analysis (maths, evaluation)
  • logical reasoning
20
Q

right hemisphere specialisation

A

receive and process sensations from left side of body
-control voluntary movements on the left side of the body
- non-verbal tasks and processing the ‘whole’ (rather than bits)
- Spatial and visual thinking ( visualising a location, solving puzzle)
- Fantasy (daydreaming )
- Appreciation of art and music
- recognising emotions (reading body language)

21
Q

structures in temporal lobe and their functions

A

Wernicke’s area - speech comprehension and production

auditory cortex- receives and processes sounds from both ears for auditory perception

22
Q

frontal lobe structures and their functions

A

Borca’s area- speech production and comprehension

primary motor cortex- control of voluntary bodily movements (left controls right and vice versa)

23
Q

parietal lobe structure and function

A

primary somatosensory cortex - receive and process sensory info from the skin and body for perception of bodily sensations

24
Q

occipital lobe structure and function

A

primary visual cortex- receive and process visual info from eyes ( left processes info from right and vice versa

25
Q

first brain experiments

A

-brain ablation
-electrical stimulation of the brain
-neuroimaging techniques

26
Q

temporal lobe structures and function

A

Werniks area- speech comprehension and production

auditory cortex- receivex and processes sounds from both ears for auditory perception

27
Q

brain injury def

A

any type of brain damage or disorder that impairs or interferes with the normal functioning of the brain, either temporarily or permanently

28
Q

traumatic brain injury def

A

type of acquired brain injury that occurs when an external force causes damage to the brain

29
Q

stroke definition, types

A

occurs when blood supply to part of the brain in interrupted

ischaemic- blood supply is stopped dude to blocked vessel

haemorrhagic- vessel supplying blood to brain gets weak and bursts causing brain bleed

30
Q

Stroke symptoms, effect and treatment

A

symptoms: slurred speech, numbness or weakness in face, arm , leg or one side of the body, loss of balance and coordination etc
effects everyone differently depending on stroke type, area of damage and the individual

rehab can help people relearn and find new ways of doing things

31
Q

epilepsy definition, types and symptoms

A

neurological disorder involving recurrent spontaneous seizures brought on by interference in normal brain activity
- facial- start in one brain area or hemisphere and affect the areas controlled
- generalised
- unknown onset

  • loss of consciousness
    -amnesia
    -jerking, shaking movements, loss of postural sup[port
32
Q

possible causes and treatments for seizure

A

TBI
brain tumor
stroke-lack of oxygen to the brain
-surgery or meds

33
Q

CTE concussion

A

type of TBI caused by a blow to the head or hit to the body that causes the brain to move rapidly back and forth

34
Q

brain injury affect bio, psych and social

A

B- dizziness
- balance problems
- impaired speech, reading, writing
P- memory problems
-behavioural changes
-difficulty problem solving
S- social isolation -difficulty making and keeping friends
-social role changes
