Methods in Cognitive Neuroscience

Question 1

What is cognitive neuroscience?

Answer 1

Looks at brain function on a thinking level and how that relates to behaviour

Question 2

What is cognitive psychology?

Answer 2

Looks at complex mental processes e.g. perception and learning

Question 3

Are EEG’s predictable?

Answer 3

Yes across individuals in the same state have similar EEGs

Question 4

What can EEGs be used to detect?

Answer 4

Brain activity, including abnormal brain activity like seizures

Question 5

Do you have to do lots of EEGs?

Answer 5

Yes to cancel out background noise or any mistakes

Question 6

What are event related potentials (ERPs)?

Answer 6

Stereotyped EEG responses to a particular stimulus

Question 7

What is latency?

Answer 7

Time taken from stimulus presentation to brain reacting

Question 8

How is the spatial resolution of EEGs?

Answer 8

Bad as measured from scalp so hard to tell where signals are actually coming from

Question 9

How is the temporal resolution of EEGs?

Answer 9

Good!

Question 10

What are 3 structural imaging techniques?

Answer 10

CT, MRI and DTI

Question 11

How does CT work?

Answer 11

Uses X-rays to see brain structure based on density. Has bad resolution

Question 12

What does DTI show?

Answer 12

White matter tracts

Question 13

What are 2 functional imaging techniques?

Answer 13

PET and fMRI
