Brain Connectome

A brain connectome is a map of the connections between different regions of the brain. It can be represented as a network, with the brain regions represented as nodes and the connections between them represented as edges. The connectome can be used to study how different regions of the brain communicate with each other, and how this communication is affected by various factors such as disease, aging, and environmental influences.

Introduction

Welcome to the Brain Signature Database

The Brain Signature Database is a comprehensive collection of brain connectivity patterns, or "signatures," that have been analyzed using graph theory. Graph theory is a branch of mathematics that studies the relationships between objects and their connections to one another. In the context of brain connectivity, these objects are typically brain regions, and the connections between them represent the strength and direction of the communication between these regions.

By applying graph theory to brain connectivity data, we can extract meaningful insights about the organization and function of the brain. For example, we can measure the "centrality" of a brain region, which reflects its importance or influence within the brain network. We can also measure the "path length" between brain regions, which reflects the shortest distance between them. These and other measures of brain connectivity, or "brain signatures," can provide valuable information about brain function and dysfunction.

The Brain Signature Database allows researchers and clinicians to access and compare brain connectivity patterns from a variety of sources. Each entry in the database includes a unique ID, as well as measures of degree centrality, betweenness centrality, path length, and clustering, along with any additional fields that may be relevant. The database also includes raw data and detailed signature data for each entry, allowing users to explore the data in greater depth.
