Hierarchical Genetic Organization of Human Cortical Surface Area

TLDR
Using a data-driven, fuzzy clustering technique with magnetic resonance imaging data from 406 twins, this work parceled cortical surface area into genetic subdivisions, creating a human brain atlas based solely on genetically informative data.
Abstract
Surface area of the cerebral cortex is a highly heritable trait, yet little is known about genetic influences on regional cortical differentiation in humans. Using a data-driven, fuzzy clustering technique with magnetic resonance imaging data from 406 twins, we parceled cortical surface area into genetic subdivisions, creating a human brain atlas based solely on genetically informative data. Boundaries of the genetic divisions corresponded largely to meaningful structural and functional regions; however, the divisions represented previously undescribed phenotypes different from conventional (non-genetically based) parcellation systems. The genetic organization of cortical area was hierarchical, modular, and predominantly bilaterally symmetric across hemispheres. We also found that the results were consistent with human-specific regions being subdivisions of previously described, genetically based lobar regionalization patterns.

The ENIGMA Consortium: large-scale collaborative analyses of neuroimaging and genetic data

TL;DR: The ENIGMA Consortium has detected factors that affect the brain that no individual site could detect on its own, and that require larger numbers of subjects than any individual neuroimaging study has currently collected.

Probabilistic Maps of Visual Topography in Human Cortex

TL;DR: Overall, the probabilistic atlases quantify the variability of topographic representations in human cortex and provide a useful reference for comparing data across studies that can be transformed into these standard spaces.

The modular and integrative functional architecture of the human brain.

TL;DR: A network account of the brain’s modular yet integrated implementation of cognitive functions is provided and a strong spatial correspondence between the cognitive functions and the network”s modules is found, suggesting that each module performs a discrete cognitive function.

Finding Groups in Data

TL;DR: In this article, an electrical signal transmission system for railway locomotives and rolling stock is proposed, where a basic pulse train is transmitted whereof the pulses are of a selected first amplitude and represent a train axle count, and a spike pulse of greater selected amplitude is transmitted, occurring immediately after the axle count pulse to which it relates, whenever an overheated axle box is detected.
