18
Q

Structure tells us…

A

about the morphology or form of things

19
Q

Function tells us…

A

about activity

20
Q

Define invasive

A

Puncture or incision of the skin and denoting
procedures or tests that require an insertion of an
instrument or material that is foreign into the body

21
Q

What is the difference between Spatial and Temporal Resolution?

A

Spatial resolution refers to how clear in space the data is taken (where something is located) where as Temporal refers to how clear in time the image is taken (when something happened)

22
Q

Correlation

A

a reliable relationship between two things

23
Q

Correlation denotes cause.

True or False?

A

False

24
Q

Reaction times, detection thresholds and stimulus discrimination are examples of what?

A

Behavioural Response research methods

25
Q

Startle response and Electrodermal activity (EDA) are examples of what?

A

Physiological response research methods

26
Q

Why is the startle response reliable?

A

Its a brainstem reflex for protection

27
Q

What is an EDA and what does it measure?

A

Electrodermal Activity and is a measure of emotional arousal

28
Q

Name some causal research methods

A

Acquired Brain Injury

Lesion Studies

29
Q

Acquired brain damage is …

A

any brain damage acquired after birth

30
Q

Lesions studies are…

A

Removing or disabling a portion of the brain and observing the resulting
behaviour.

31
Q

Negative of lesion studies?

A

rarely administered with 100% accuracy

32
Q

Transcranial direct current stimulation, drug blocks, cryogenic blocks and transcranial magnetic stimulation are examples of….

A

Stimulation and disrupting brain activity

33
Q

What is MEG and describe?

A

Magneto-encephalography
Electric currents generate small magnetic fields which can be measured at the scalp. It provides high temporal resolution but only provides correlation data.

34
Q

What is EEG and describe?

A

Electroencephalography
Electrical activity generates electric fields which can be measured at the scalp level with many nodes attached to the scalp. Correlational data only

35
Q

PET is…

A

Positron Emission Tomography

Radioactive isotope is used to trace activity

36
Q

MRI is…

A

Magnetic Resonance Imaging

37
Q

DTI is ….

A

Diffusion Tension Imaging

variant of MRI measures motion of water molecules and shows mostly the axon fibres

38
Q

fMRI is …

A

Functional Magnetic Resonance Imaging
Indirect measure of neuronal
activity, measures the flow of blood in the brain. Provides structural and functional in the same image.
