1

what experimental, clinical, and cognitive neuropsychology mean

e - experimenting on healthy humans
cl - applying knowledge to patients with brain injuries
co - studying people with brain damage

2

what cognitive deficits arise from brain damage

langage, vision , exec control, motor programming

3

what is dysexecutive syndrome

problems with memory, planning and organisation

4

what is synesthesia

you see words as colours

5

what are group studies?

common diagnosis or damage in a common region

6

problem with group studies

variability among patients in a group

7

what is a dissociation

showing that damage to a particular brain structure disrupts on aspect of a complex mental process but not another

8

example of a single dissociation

clive wearing - dissociation between diff types of memory

9

problem with a single dissociation ?

2 tasks may differ in complexity - two people may differ in how good they are at it.
dissociation could be due to ability of person therefor alter results

10

what is a double dissociation

A disrupts Z while leaving Y B disrupts Y while leaving Z
BEST EVIDENCE that areas are functionally distinguished

11

How does an MRI work

radiowaves cause protons H+ in brain to spin... reciever then detects their spin and generates an imagine

12

whats does a VBM show

differences in grey matter

13

how does fMRI work

measures changes in cerebral blood flow following brain activity - active areas have LOW oxy haemoglobin and HIGH deoxy - blood flow to area which increases the ratio oxy:deoxy

14

problems with fMRI

time resolution. noise, claustrophobia, signal indirect measure of neural activity

15

How does EEG work

measures brain activity- scalp electrodes provide continous recording.

16

when are EEGs used

comas, epileptics, sleep therapy, anaethesia

17

2 pros to EEGs

inexpensive + non invaisive

18

1. What is an ERP
2. 3 +ves

1. evoked electrical activity specifically related to sensory motor and cognitive defects
2.
- NON invaisive electrodes on head
- exact timing
- low cost
