Brain shiftNonlinear biomechanical modelsIn this chapter we present an algorithm for computing the displacement of the exposed surface of the brain during surgery. The motion of the cortical surface is recovered by registering the preoperative surface extracted from high-resolution MRI images to the ...

Automated routines for unfolding and flattening the cortical surface are described in a companion paper. These procedures allow for the routine use of cortical surface-based analysis and visualization methods in functional brain imaging. 展开 关键词: segmentation cortical surface reconstruction....
We found significantly larger scaling exponents than geometrically predicted for cortical surface area, absolute mean curvature in sulcal regions and in sulcal walls, and smaller ones for cortical volume and thickness. As brain size increases, the cortex thickens only slightly, but the degree of ...
The reconstruction of cortical surfaces from brain magnetic resonance imaging (MRI) scans is essential for quantitative analyses of cortical thickness and sulcal morphology. Although traditional and deep learning-based algorithmic pipelines exist for this purpose, they have two major drawbacks: lengthy runt...

PySurfer is a Python package for interacting with a cortical surface representations of neuroimaging data. It extends Mayavi's powerful visualization engine with a high-level interface for working with MRI and MEG data. PySurfer offers both a command-line interface designed to broadly the Freesurfer ...
A horizontal and vertical dipole layer model was developed for three dimensional dipole layer imaging of brain electrical activity. Horizontal dipole layer being parallel to the brain surface has been used in previous head models. In the present study, the dipole layer distribution in the sagittal ...
