What is ICN?
Intrinstic connectivity network
1 of 20
Where are the 7 main ICN's?
In the brain
2 of 20
What are ICN'S?
Networks of _____ areas that communicate with each other,
3 of 20
Functional connectivity?
2 brain regions that show the similar neural activity, are assumed to communicate and be connected
4 of 20
FMRI functional connectivity?
Reflects underlyingg neural connection of brain region
5 of 20
What is it good at?
Very good at reflecting functional architecture/link in the brain
6 of 20
What functions do ICN's reflect?
Auditory, visual, attention, DMN
7 of 20
Meaning functional connectivity?
Didn't answer this one I couldn't read it
8 of 20
Interpretation?
Gain an R-Value correlation
9 of 20
What is R value?
High FC between brain areas, activity is very similar, part of ___ ICN, R value close to 0; no functional connectivity between areas, nothing is common, R value is negative: inverse correlation, activity is opposite
10 of 20
Extra info about FC?
Can also see FC to specific area - measure every voxel in brain and see correlation for each vexed intum
11 of 20
ICN negative?
Large ICN'S not specific enough, can find smaller scale networksICN'S by using smaller ROI'S
12 of 20
Case beginning with R?
Raichle 2001: DNM active during test and inhibited 'turned off' during tests, area of inverse FC
13 of 20
Case beginning with L?
Leech 2012: PCC (postentor cingulate cortex) Different areas have different types of connectivity, highly connected to much of the brain
14 of 20
Case beginning with P?
Power 2012 - head movements of pp produce substantial changes in FMRI readings, although their one compensatory algorithm it senses correlation networks - suggested implementing standard realignment + _____ ____ analysis
15 of 20
Case beginning with C?
Cole 2013 - Multitask network centre - FPN coordinates networks and brain regions during task performance, an executive control
16 of 20
FC?
FC varies by individuals, some ICN'S continue more to same and then others = identifying fingerprint
17 of 20
Case beginning with F?
Finch 2015 - Fluid intelligence (no prior knowledge) can be predicted from brain connectivity
18 of 20
EEG results?
From checking EEG results to FMRI results can validate activity at rest (continued next question)
19 of 20
Case beginning with S?
Scholvnich 2010 - LFP + BOLD = very strong similarity - born recorded from PC - potential cortex
