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
