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 ...
Network science. In mathematics, computer science and network science, network theory is a part of graph theory. It defines networks as graphs where the vertices or edges possess attributes. Network theory analyses these networks over the symmetric relations or asymmetric relations between their (discrete) components.
A small-world network is a graph characterized by a high clustering coefficient and low distances. On an example of social network, high clustering implies the high probability that two friends of one person are friends themselves. The low distances, on the other hand, mean that there is a short chain of social connections between any two ...
A hub is a component of a network with a high-degree node. Hubs have a significantly larger number of links in comparison with other nodes in the network. The number of links (degrees) for a hub in a scale-free network is much higher than for the biggest node in a random network, keeping the size N of the network and average degree <k> constant.
Network neuroscience is an approach to understanding the structure and function of the human brain through an approach of network science, through the paradigm of graph theory. [1] A network is a connection of many brain regions that interact with each other to give rise to a particular function. [2] Network Neuroscience is a broad field that ...
Visualization of fibers was done using TrackVis software. [1] A connectome (/ kəˈnɛktoʊm /) is a comprehensive map of neural connections in the brain, and may be thought of as its "wiring diagram". [2] An organism 's nervous system is made up of neurons which communicate through synapses. A connectome is constructed by tracing the neuron in ...
An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub[a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of ...
Network science is an academic field which studies complex networks such as telecommunication networks, computer networks, biological networks, cognitive and semantic networks, and social networks, considering distinct elements or actors represented by nodes (or vertices) and the connections between the elements or actors as links (or edges).
