The genetic architecture of language functional connectivity [PDF]

NeuroImage, 2021
AbstractLanguage is a unique trait of the human species, of which the genetic architecture remains largely unknown. Through language disorders studies, many candidate genes were identified. However, such complex and multifactorial trait is unlikely to be driven by only few genes and case-control studies, suffering from a lack of power, struggle to ...

Questions and controversies in the study of time-varying functional connectivity in resting fMRI

Network Neuroscience, 2020
The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and the

Regularized Functional Connectivity in Schizophrenia

Frontiers in Human Neuroscience, 2022
Regularization may be used as an alternative to dimensionality reduction when the number of variables in a model is much larger than the number of available observations. In a recent study from our group regularized regression was employed to quantify brain functional connectivity in a sample of healthy controls using a brain parcellation and resting ...

Topographic organization of the human subcortex unveiled with functional connectivity gradients

Nature Neuroscience, 2020
Brain atlases are fundamental to understanding the topographic organization of the human brain, yet many contemporary human atlases cover only the cerebral cortex, leaving the subcortex a terra incognita.

The Role of Corpus Callosum Development in Functional Connectivity and Cognitive Processing [PDF]

, 2012
The corpus callosum is hypothesized to play a fundamental role in integrating information and mediating complex behaviors. Here, we demonstrate that lack of normal callosal development can lead to deficits in functional connectivity that are related to ...

Functional Connectivity in Aging [PDF]

, 2019
A large body of research shows that aging is accompanied by localized changes in brain structure and function. However, over the past decade the neuroimaging community has begun to recognize the importance of investigating the brain as a network.

High-amplitude cofluctuations in cortical activity drive functional connectivity

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Despite widespread applications, the origins of functional connectivity remain elusive. Here we analyze human functional neuroimaging data. We decompose resting-state functional connectivity across time to assess the contributions of moment ...

On the role of the corpus callosum in interhemispheric functional connectivity in humans [PDF]

, 2017
Resting state functional connectivity is defined in terms of temporal correlations between physiologic signals, most commonly studied using functional magnetic resonance imaging. Major features of functional connectivity correspond to structural (axonal)

Nonequilibrium Green’s Functions for Functional Connectivity in the Brain [PDF]

Physical Review Letters, 2021
A theoretical framework describing the set of interactions between neurons in the brain, or functional connectivity, should include dynamical functions representing the propagation of signal from one neuron to another. Green's functions and response functions are natural candidates for this but, while they are conceptually very useful, they are usually
