Activities of monoamine oxidase (MAO) A and B in discrete regions of rat brain after rapid eye movement (REM) sleep deprivation
(Elsevier B.V., 1997-10-01)Rapid eye movement (REM) sleep deprivation increases monoaminergic (noradrenergic and serotonergic) turnover and their metabolites in whole brain of rats. This increase in metabolites may indicate increased activity of the ...

Brain prolactin is involved in stress-induced REM sleep rebound
(Academic Press Inc Elsevier Science, 2017)REM sleep rebound is a common behavioural response to some stressors and represents an adaptive coping strategy. Animals submitted to multiple, intermittent, footshock stress (FS) sessions during 96 h of REM sleep deprivation ...

Decreased activity of striatal monoamine oxidase B after rapid eye movement (REM) sleep deprivation in rats
(Elsevier B.V., 1998-05-01)The striatum seems to be the main brain region involved in stereotyped behavior induced by dopaminergic agonists. Rapid eye movement (REM) sleep deprivation increases dopaminergic agonist-induced stereotypy and produces ...

Immune alterations after selective rapid eye movement or total sleep deprivation in healthy male volunteers
(Sage Publications Ltd, 2012-02-01)We investigated the impact of two nights of total sleep deprivation (SD) or four nights of rapid eye movement (REM) SD on immunological parameters in healthy men. Thirty-two volunteers were randomly assigned to three ...

Rapid eye movement (REM) sleep deprivation reduces rat frontal cortex acetylcholinesterase (EC 3.1.1.7) activity
(Assoc Bras Divulg Cientifica, 1997-05-01)Rapid eye movement (REM) sleep deprivation induces several behavioral changes. Among these, a decrease in yawning behavior produced by low doses of cholinergic agonists is observed which indicates a change in brain cholinergic ...

Rapid eye movement sleep deprivation induces an increase in acetylcholinesterase activity in discrete rat brain regions
(Associação Brasileira de Divulgação Científica, 2001-01-01)Some upper brainstem cholinergic neurons (pedunculopontine and laterodorsal tegmental nuclei) are involved in the generation of rapid eye movement (REM) sleep and project rostrally to the thalamus and caudally to the medulla ...

Rapid eye movement sleep deprivation induces changes in the high-affinity binding of [H-3]-ouabain to the rat cortical membranes
(Elsevier B.V., 2006-03-27)Rapid eye movement sleep (REMS) suppresses seizures. On the other hand, REMS deprivation (REMSD) increases brain susceptibility to seizures. Sodium-postassium/ATPase is involved in the control of brain excitability. Ouabain, ...

Rapid eye movement sleep deprivation-induced down-regulation of beta-adrenergic receptors in the rat brainstem and hippocampus
(Elsevier B.V., 2004-09-01)Rapid eye movement (REM) sleep deprivation induces a cortical down-regulation of beta-adrenergic receptors. Down-regulation of cortical beta-adrenergic receptors is consistently observed after a number of different chronic ...

Vulnerabilidade e Resiliência ao Estresse: Aspectos ontogenéticos das consequências comportamentais, neuroendócrinas e neuroquímicas
(Universidade Federal de São Paulo (UNIFESP), 2013)This Full Professorship thesis portrays a current and frequently present matter in human daily life, Stress. By means of a broad literature overview, I intend to present the biological foundation of the hormonal and ...
