Brain network


A "brain network" typically refers to the complex interconnected system of neurons and regions in the human brain that work together to process information, control bodily functions, and generate thoughts, emotions, and behaviors. The brain's network structure is a crucial aspect of its functionality and is studied extensively in the fields of neuroscience, psychology, and cognitive science


Structural Brain Networks: These networks focus on the physical connections between different brain regions. They are often represented using graphs, where nodes represent brain regions and edges represent the anatomical connections between them. Techniques like diffusion tensor imaging (DTI) are used to map the pathways of white matter tracts in the brain, providing insights into its structural connectivity..

Functional Brain Networks: These networks are based on the patterns of neural activity and communication between brain regions. Functional connectivity is measured by analyzing the synchronization of neural activity in different brain areas. Functional brain networks help researchers understand how different regions cooperate during various cognitive tasks and at rest.

Connectome:
The connectome is a comprehensive map of all the connections in the brain, encompassing both functional and structural connections. It's a complex representation of the brain's wiring diagram and is a significant area of study in neuroscience.

Specific Task Networks: Different cognitive tasks involve specific networks of brain regions working together. For example, there are networks associated with language processing, visual perception, motor control, and more.

Understanding brain networks is crucial for unraveling how the brain functions as a whole and how different regions collaborate to produce thoughts, behaviors, and experiences. Advances in neuroimaging techniques and computational modeling have significantly contributed to our understanding of these networks and how they relate to various aspects of human cognition and behavior.

  Centrality Network Centrality in a network refers to the measure of the importance or significance of a node (or sometimes an edge) within that network. It helps identify which nodes play crucial roles in various network processes such as information flow, influence propagation, or resource allocation. Centrality measures are commonly used in network analysis, including social networks, transportation networks, biological networks, and more. There are several types of centrality measures, including: Degree Centrality: This is the simplest centrality measure and is based on the number of connections a node has. In a social network, it would represent how many friends a person has. Nodes with higher degrees are considered more central.   Closeness Centrality: This measure quantifies how quickly a node can reach all other nodes in the network. It is based on the length of the shortest paths from a node to all other nodes. Nodes with shorter average path lengths are considered m...

1st Edition of International Research Awards on Network Science and Graph Anlaytics, 27-28 April, London(United Kingdom)

Image
The International Conference on Network Science and Graph Analytics (NSGA) is an annual event that brings together researchers, practitioners, and industry experts from around the world to share their latest research and developments in the fields of network science and graph analytics.  These awards are typically presented by professional societies, academic organizations, and industry associations that are focused on Network Science and Graph Analytics. Some of these awards are specifically aimed at recognizing early career researchers, while others honor lifetime achievements in the field. Nominees for these awards are evaluated based on their research contributions, scientific impact, and the quality and relevance of their work. The awards often include a cash prize, a certificate, and an invitation to give a keynote speech or present their research at a conference or workshop. They provide researchers with international recognition and prestige, which can enhance their career ...
