Human brain parcellation using time courses of instantaneous connectivity
Recent functional neuroimaging studies have shown that the brain can be divided into several spatially separate, functionally distinct networks. The investigation of these networks has become an active field of research to understand the brain as a set of interacting subunits. Key to this understanding is the manner in which these network break down into smaller fundamental subregions, and how ...
متن کاملIntrinsic functional connectivity pattern based brain parcellation using normalized cut
In imaging data based brain network analysis, a necessary precursor for constructing meaningful brain networks is to identify functionally homogeneous regions of interest (ROIs) for defining network nodes. For parcellating the brain based on resting state fMRI data, normalized cut is one widely used clustering algorithm which groups voxels according to the similarity of functional signals. Due ...
متن کاملHierarchical Information-Based Clustering for Connectivity-Based Cortex Parcellation
One of the most promising avenues for compiling connectivity data originates from the notion that individual brain regions maintain individual connectivity profiles; the functional repertoire of a cortical area ("the functional fingerprint") is closely related to its anatomical connections ("the connectional fingerprint") and, hence, a segregated cortical area may be characterized by a highly c...
متن کاملConnectivity-Driven Parcellation Methods for the Human Cerebral Cortex
The macro connectome elucidates the pathways through which brain regions are structurally connected or functionally coupled to perform cognitive functions. It embodies the notion of representing, analysing, and understanding all connections within the brain as a network, while the subdivision of the brain into interacting cortical units is inherent in its architecture. As a result, the definiti...
متن کاملA Continuous Flow-Maximisation Approach to Connectivity-Driven Cortical Parcellation
Brain connectivity network analysis is a key step towards understanding the processes behind the brain’s development through ageing and disease. Parcellation of the cortical surface into distinct regions is an essential step in order to construct such networks. Anatomical and random parcellations are typically used for this task, but can introduce a bias and may not be aligned with the brain’s ...
