Networks/connectivity in Psychiatry Flashcards
1
Q
difference structural and functional connectivity
A
- structural is basically counting the physiscal wires/connections in one place.
- functional is looking at the connectivity between two brain regions
2
Q
hoe meet je beide structural and functional connectivity
A
structural -> via DTI, functional -> via fMRI
3
Q
what is the connectome
A
a map of all connectivity in the brain
4
Q
what is an edge?
A
a connection, an axon, functional brain activity between nodes
5
Q
what is a node?
A
neurons or brain regions
6
Q
how could you use this in research?
A
describe the network of a certain subject, and then check the wire differences in patients and controls
7
Q
how can you use this in the clinic?
A
- use it in early stages of the disease, check for outcome -> predictive
- use as a screening before onset -> predictive
- differences in patients -> which patient would respond well to what drug?
8
Q
descriptive definition
A
difference between patients and controls
9
Q
predictive
A
predict the difference in patients and controls, later on predict the differences in patients.
10
Q
cross over
A
bc default network -> has a big effect on AD, PD etc?
