Reliable local dynamics in the brain across sessions are revealed by whole-brain modeling of resting state activity
(Wiley-liss, div John Wiley & Sons Inc., 2019-03)
Resting state fMRI is a tool for studying the functional organization of the human brain. Ongoing brain activity at “rest” is highly dynamic, but procedures such as correlation or independent component analysis treat ...
The conundrum of functional brain networks: Small-world efficiency or fractal modularity
(Frontiers Editorial, 2012-05)
The human brain has been studied at multiple scales, from neurons, circuits, areas with well-defined anatomical and functional boundaries, to large-scale functional networks which mediate coherent cognition. In a recent ...
Ising-like dynamics in large-scale functional brain networks
(American Physical Society, 2009-12)
Brain "rest" is defined-more or less unsuccessfully-as the state in which there is no explicit brain input or output. This work focuses on the question of whether such state can be comparable to any known dynamical state. ...
24S‐hydroxycholesterol: cellular effects and variations in brain diseases
(Wiley Blackwell Publishing, Inc, 2020-05)
The adult brain exhibit a characteristic cholesterol homeostasis, with low synthesis rate and active catabolism. Brain cholesterol turnover is possible thanks to the action of the enzyme Cytochrome P450 46A1 (CYP46A1) or ...
State-dependent changes of connectivity patterns and functional brain network topology in autism spectrum disorder
(Pergamon-Elsevier Science Ltd, 2012-12)
Anatomical and functional brain studies have converged to the hypothesis that autism spectrum disorders (ASD) are associated with atypical connectivity. Using a modified resting-state paradigm to drive subjects' attention, ...
Cholesterol in brain disease: sometimesdeterminant and frequently implicated
(Nature Publishing Group, 2014-09)
Cholesterol is essential for neuronal physiology, both during development and in the adult life: as a major component of cell membranes and precursor of steroid hormones, it contributes to the regulation of ion permeability, ...
Brain circuits mediating the orexigenic action of peripheral ghrelin: Narrow gates for a vast kingdom
(Frontiers Research Foundation, 2015-03)
The nervous and endocrine systems act together to regulate all physiological processes essential for the body homeostasis control. Given the strict communication restrictions that the brain-blood barrier (BBB) imposes, the ...
Oestrogens and Progestagens: Synthesis and Action in the Brain
(Wiley Blackwell Publishing, Inc, 2016-07)
When steroids, such as pregnenolone, progesterone and oestrogen, are synthesised de novo in neural tissues, they are more specifically referred to as neurosteroids. These neurosteroids bind specific receptors to promote ...
Brain and Behavior of Dromiciops gliroides
(Springer, 2019-01)
AbstractWe have analyzed the internal structure of the brain of the microbiotherian marsupial Dromiciops gliroides and compared it with the brains of American and Australian marsupials. Dromiciops does not have a fasciculus ...
