Understanding brain regions via functional repertoires: multidimensional Regions Passingham et al. (2002)
7
Understanding brain regions via functional repertoires: imaging data BrainMap NeuroSynth Task domains (ontology)
8
Understanding brain regions via functional repertoires: imaging data
9
Regions will be more or less “diverse” Use Shannon Entropy Anderson, Kinnison, and Pessoa (2013), Neuroimage

Network fingerprint

Fronto-parietal “attention” network (co-activation of BrainMap data) Toro et al. (2008)
15
Cingulo-parietal “resting-state” network (co-activation of BrainMap data) Toro et al. (2008)
17
Deen et al. (2010)

21
Common fingerprint All insula sub-sectors are highly diverse (cf. tripartite cognitive-affective-interoceptive scheme)
22
“Specific” fingerprint components Left dorsal anterior insula mean Phonology Working memory Reasoning … Sadness Happiness Fear …
23
“Specific” fingerprint components Dorsal Posterior Ventral “Cognitive” “Affective”
24
Fronto-parietal: “attention” Cingulo-opercular: “resting-state” Dorsal attention: “endogenous attention” Ventral attention: “exogenous attention” Fronto-parietal: “rapid adaptive control” Cingulo-opercular: “stable set control” List goes on and on… Toro et al. (2008)
25
Task positiveTask negative
26
Evaluate whether two sets (i.e., networks) of fingerprints are drawn from the same parent distribution “Statistical energy” (Aslan and Zech, 2005)
27
Statistical energy X Y
28
Permutation testing of ϕ XY Task-positive vs. Task-negative (co-activation data) Task-positive (co-activation; Toro et al. 2008) vs. Dorsal attention (resting-state; Yeo et al. 2011)
29
Assortativity: “like connects with like”
30
Statistical energy “Functional distance” Pairs of regions within a network Pairs of regions between networks X Y Z
31
Networks
32
“Dorsal attention”
33
“Ventral attention”
34
“Default network” Dis-assortative
35
“Default network”: should fragment into several subnetworks Dis-assortative
36
Characterize contributions of individual brain regions and networks without using singular task-bound functional attributions Described quantitative property of networks – functional assortativity – that can be useful in understanding the functional and compositional similarities and differences between networks
