Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Large-scale brain network?Somato network, Default network, Visual network
2. What is the primary detection method?Statistical analysis of fMRI BOLD signals, EEG, PET, MEG
3. What is the network architecture?Graph-like structure with nodes (brain regions) and edges (functional connections)

Functional Connectivity: Statistical measure of the temporal correlation between the activity of spatially distinct brain regions.
Intrinsic Brain Networks: Widespread collections of brain regions exhibiting consistent functional connectivity, often studied during resting states.
BOLD Signal: Blood-Oxygen-Level-Dependent signal, a measure of brain activity used in fMRI that reflects changes in blood flow and oxygenation.
Default Mode Network (DMN): A network primarily active during introspective thought, mind-wandering, and self-referential processing, showing decreased activity during externally focused tasks.
