Pattern based morphometry (PBM) is a method of brain morphometry first put forth in PBM. [6] It builds upon DBM and VBM. PBM is based on the application of sparse dictionary learning to morphometry. As opposed to typical voxel based approaches which depend on univariate statistical tests at specific voxel locations, PBM extracts multivariate ...
Voxel-based morphometry is a computational approach to neuroanatomy that measures differences in local concentrations of brain tissue, through a voxel-wise comparison of multiple brain images. [ 1 ] [ 2 ] In traditional morphometry , volume of the whole brain or its subparts is measured by drawing regions of interest (ROIs) on images from brain ...
Morphometrics (from Greek μορϕή morphe, "shape, form", and -μετρία metria, "measurement") or morphometry [5] refers to the quantitative analysis of form, a concept that encompasses size and shape. Morphometric analyses are commonly performed on organisms, and are useful in analyzing their fossil record, the impact of mutations on ...

The human brain is unique from other species based on the size of the visual cortex, temporal lobe, and parietal cortex, and increased gyrification (folds of the brain). There have been many questions as to why these changes occurred and how they contributed to cognition and behavior, which are important questions in human evolution.
Neuromorphology has been used as a new method of exploring the underlying cause of many neurological disorders, and has been included in the clinical study of various neurodegenerative diseases, mental disorders, learning disabilities, and dysfunctions due to brain damage. Researchers have been using neuromorphological techniques to not only ...
Functional magnetic resonance imaging data. Functional neuroimaging is the use of neuroimaging technology to measure an aspect of brain function, often with a view to understanding the relationship between activity in certain brain areas and specific mental functions.
Functional brain imaging techniques, such as functional magnetic resonance imaging , are common in neuroimaging but rarely used in neuroradiology. Neuroimaging falls into two broad categories: Structural imaging, which is used to quantify brain structure using e.g., voxel-based morphometry.
