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 ...
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 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 ...
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. ...
Sexual responses to intrauterine stress: body and brain growth
(I R O G Canada, Inc, 2002-04)
The aims of this work were to analyse body and brain growth as produced by deficiencies in the uteroplacenta bllood supply,and to evaluate sexual responses to intrauterine stress. Intrauterine growth retardation(IUGR) was ...
Brain volume, energy balance, and cardiovascular health in two nonindustrial South American populations
(National Academy of Sciences, 2023)
Little is known about brain aging or dementia in nonindustrialized environments that are similar to how humans lived throughout evolutionary history. This paper examines brain volume (BV) in middle and old age among two ...
From molecule to behavior: Brain aromatase (cyp19a1b) characterization, expression analysis and its relation with social status and male agonistic behavior in a Neotropical cichlid fish
(Academic Press Inc Elsevier Science, 2017-03)
The enzyme aromatase, responsible for the conversion of C19 androgens to C18 estrogens, exists as two paralogue copies in teleost fish: Cyp19a1a mostly expressed in the gonads, referred as gonadal aromatase, and Cyp19a1b, ...
Treating Metastatic Brain Cancers With Stem Cells
(Frontiers Media S.A., 2021-11-24)
Stem cell therapy may present an effective treatment for metastatic brain cancer and glioblastoma. Here we posit the critical role of a leaky blood-brain barrier (BBB) as a key element for the development of brain metastases, ...
Oxidative balance in brain after exposure to arsenic in ex vivo and in vivo models
(International Journal of advanced research, 2017-10)
The hypothesis of this work was that radical generation after exposure<br />to As may contribute to its toxic effects in the brain tissues. Oxidative<br />status of brain was studied, both using ex vivo and in vivo protocols ...
