Q

PET

A
  • Gives info on not only brain structure but also activity and function
  • Records the use of glucose by cells in the brain
  • Less detailed than MRI
17
Q

Brain lesioning

A
  • Studying the effects of damage to an area of the brain
  • Helpful for making initial discoveries of the brain
18
Q

Split brain surgery

A
  • Cutting the band (corpus callosum) of nerve tissue connecting the two hemispheres
  • Treatment for epilepsy
19
Q

Neuroplasticity

A

The ability of neural networks in the brain to change as a result of an experience or enviro stimuli.

20
Q

Acquired brain injury

A
  • Injury resulting from damage to the brain occurring after birth, at any time during life.
  • Interferes with the brain’s normal functioning
21
Q

Biological impacts

A
  • Impaired sensory functioning

24
Q

Traumatic brain injury

A
  • Damage to the brain
  • Caused by an external force
  • E.g. falls, vehicle accidents
25
Q

Non-traumatic brain injury

A

Observed through

26
Q

Sprouting

A

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

27
Q

Rerouting

A

When healthy nearby neurons create alternative neural pathways after existing connections are lost through injury

28
Q

CTE

A
  • A progressive and fatal brain disease
  • Associated with repeated head injuries and concussions
29

33
Q

Sample

A

The participants selected from the population, who participate in the investigation.

34
Q

Hypothesis

A

A statement outlining the probable outcomes of an investigation.
