The Brain Imaging Data Structure (BIDS) is a standard for organizing, annotating, and describing data collected during neuroimaging experiments. It is based on a formalized file and directory structure and metadata files (based on JSON and TSV ) with controlled vocabulary . [ 1 ]
An example that identified 10 large-scale brain networks from resting state fMRI activity through independent component analysis [15]. Because brain networks can be identified at various different resolutions and with various different neurobiological properties, there is currently no universal atlas of brain networks that fits all circumstances. [16]
The goal of the Human Connectome Project is to build a "network map" that will shed light on the anatomical and functional connectivity within the healthy human brain, as well as to produce a body of data that will facilitate research into brain disorders such as dyslexia, autism, Alzheimer's disease, and schizophrenia.

The human brain network was characterized using a broad array of network analysis methods including core decomposition, modularity analysis, hub classification and centrality. Hagmann et al . presented evidence for the existence of a structural core of highly and mutually interconnected brain regions, located primarily in posterior medial and ...
For example, the AntibodyRegistry combines data from 200+ vendors, the NIF Integrated BrainGeneExpression combines gene expression data from Gensat, Alan Brain, and Mouse Genome Informatics, the Connectivity view combines six databases that have statements about nervous system connectivity, the Integrated Animal view combines data about ...
The default mode network is an interconnected and anatomically defined [4] set of brain regions. The network can be separated into hubs and subsections: Functional hubs: [25] Information regarding the self Posterior cingulate cortex (PCC) & precuneus: Combines bottom-up (not controlled) attention with information from memory and perception. The ...
The Default Mode Network (DMN) is a large-scale brain network that is active while the brain is at wakeful rest. [20] It was initially noticed to be deactivated during external goal oriented tasks, specifically tasks involving visual attention or cognitive working memory. [20] Because of this, it was referred to as a task-negative network. [20]
