Q

Brain damage

A

can occur through disease or trauma as well as the use of drugs and alcohol

30
Q

Rerouting

A

healthy neurons seek an alternative route when existing connections are lost

31
Q

Sprouting

A

existing neurons form new axon terminals and dendrites to allow new connections to be made

32
Q

Maximising and maintaining our brain

A

Mental stimulation - any activity that activates or enriches the mind
good diet and exercise

33
Q

Dendrites

A

branch like extensions on a neuron, passes info and is connected to the cell body

34
Q

cell body

A

contains the nucleus, brain of the neuron, passes information to the axon

35
Q

axon

A

nerve fibre of neuron, goes through the whole thing. transmits information to other neurons

36
Q

Myelin Sheath

A

Layer of insulation around the axon which protects and speeds up electrical charge

37
Q

Axon terminal/Axon buttons

A

end of the neuron, connects to other dendrites to pass information

38
Q

Aquired brain injury (ABI)

A

the result of damage to the brain that happens after birth at any time during life

39
Q

Causes of ABI

A

physical injury, disease or infection, oxygen deprivation to the whole body or brain, poisoning or drugs or alcohol and brain tumours

40
Q

effect of ABI on biological factors

A

change in organ function, seizures, loss or increased sensitivity of smell or some smells

41
Q

effect of ABI on pscychological factors

A

changes in cognition, behaviour, personality, emotion and memory loss, impusivity and irritability

42
Q

effect of ABI on social factors

A

relationships, interations in the environment and interpersonal skills

43
Q

Examples of ABI

A

Stroke, Spatial neglect and Aphasia

44
Q

what is CTE

A

a neurodegenerative disease linked to repeated impacts to the head. It is progressive and fatal. The brain movement inside the skull causes a buildup of Tau protein.

45
Q

Causes of CTE

A

Contact sports (boxing, AFL, NFL), military exposure to blast impacts, head banging and domestic violence. Other possible risk factors include timing, genetics, severity, location and lifestyle

46
Q

Symptoms of CTE

A

impairments in decision making, attention and concentration, memory loss, depression, anxiety and paranoia and aggression and emotional outbursts.

47
Q

Difficulties in diagnosing CTE

A

Very similar to Alzheimer’s Disease and other neurological disorders
Can only be diagnosed in autopsy

48
Q

Phrenology

A

Assessing a person’s personality and intelligence through feeling the bumps on their skull

49
Q

Pseudosciences

A

a false science that is mistakenly regarded as being based on a scientific method, e.g. Astrology (Star Signs), Phrenology and Palmistry

50
Q

Psychology

A

The study of the brain and its functions. Derived from philosophy, which involves making predictions on human behaviour but is not based on evidence, and natural science, which is based on evidence

51
Q

Split brain surgery

A

Involves cutting the band of nerve tissure connecting the hemispheres of the brain (corpus callosum) to reduce the effect of epileptic seizures.

52
Q

What happened to Phineas Gage?

A

While working on a rail line, Gage was using gunpowder to blow up a large rock, packing it in with a large metal rod. Then, accidentally the gunpowder sparked and blew the metal rod into Gage’s cheek and all the way through the top of his skull, through his frontal lobe.

53
Q

What did we learn from Phineas Gage’s accident?

A

It taught psychologists that the frontal lobe was mostly in charge of emotions, personality, motor movements and cognitive funtions like memory and problem solving, as this is what Gage had problems with after his accident

54
Q

Case study

A

an investigation of a particular activity, behaviour or event that contains a real or hypothetical situation and real world complexities

55
Q

Hemispheric specialisation

A

some functions are only located in one side of the brain.

56
Q

corpus callosum

A

a thick bundle of nerves connecting the 2 hemispheres that allows them to communicate

57
Q

Right side hemispheric specialisation

A

creativity, appreaciation for art and music, spatial reasoning and facial recognition

58
Q

left side hemispheric specialisation

A

logical reasoning. verbal tasks including comprehension, reading and writing, and also analytical thinking.

59
Q

Central nervous system

A

Made up of brain and spinal cord. has 2 main functions - carry motor information from the brain and receive sensory information which travels to the brain

60
Q

peripheral nervous system

A

network of neurons outside the CNS. connects CNS to organs. divided into somatic and autonomic systems

61
Q

Somatic nervous system

A

mainly involved with external, carry out voluntary movement and convey sensory information

the idea that every human has a unique nervous system with a different combination of abilities and
needs

65
Q

experience dependant plasticity

A

changes that occur due to individual experience

66
Q
