WebIt is well known that individual brain anatomy and physiology can vary widely across people—thus, individual-based brain parcellation schemes were developed that considered a person's unique anatomy and physiology (Craddock et al., 2012; Gordon et al., 2024; Wig et al., 2014). These types of approaches can be difficult to use in brain ... WebThe AAL atlas is probably the most widely used cortical parcellation map in connectomic literature.

The Dice coefficient was first evaluated on each brain parcel … WebJan 1, 2004 · The procedure models the parcellation labels as a first order anisotropic non-stationary Markov random field (MRF), allowing it to capture the spatial relationships between parcellation units that are present in the training set.
WebApr 14, 2024 · Objective Automated brain volumetric analysis based on high-resolution T1-weighted MRI datasets is a frequently used tool in neuroimaging for early detection, diagnosis, and monitoring of various neurological diseases. However, image distortions can corrupt and bias the analysis. The aim of this study was to explore the variability of brain … WebIt is important to note here that alternative brain parcellation schemes could be used, as in [15,29,30]. In the proposed system, the AAL atlas was chosen because of its relatively fine granularity. Here, to make sure of the matching between the labels and the surface, the preprocessing steps of the proposed framework were first applied to ...
