Caracterização eletrofisiológica das oscilações delta e teta do hipocampo dorsal de ratos durante locomoção em esteira
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2020-06-09)
The hippocampal theta rhythm (6-10 Hz) has been extensively studied since the 1950’s. These
researches have shown that the theta rhythm is involved with cognitive functions, sensorymotor integration, paradoxical sleep and ...

Bursting Neurons in the Hippocampal Formation Encode Features of LFP Rhythms
(Frontiers Research Foundation, 2016-12)
Burst spike patterns are common in regions of the hippocampal formation such as the subiculum and medial entorhinal cortex (MEC). Neurons in these areas are immersed in extracellular electrical potential fluctuations often ...
Theta-associated high-frequency oscillations (110–160 Hz) in the hippocampus and neocortex
(2013)
We review recent evidence for a novel type of fast cortical oscillatory activity that occurs circumscribed
between 110 and 160 Hz, which we refer to as high-frequency oscillations (HFOs). HFOs characteristically
occur ...
Efeitos da privação de sono paradoxal sobre a implantação e a progressão de metástases experimentais em modelo de melanoma murino
(Universidade Federal de São Paulo (UNIFESP), 2015-04-30)
Deprivation of REM sleep (PSP) is a stress induction model because it results in a increased concentrations of glucocorticoids (GCs) in humans (cortisol) and rodents (corticosterone) and others neurotransmitters ...
Pedunculopontine arousal system physiology—Effects of psychostimulant abuse
(Elsevier, 2015-11)
This review describes the interactions between the pedunculopontine nucleus (PPN), the ventral tegmental area (VTA), and the thalamocortical system. Experiments using modulators of cholinergic receptors in the PPN clarified ...
Desvendando oscilações hipocampais através de comodulações
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2016-04-07)
Spectral analysis of extracellular electrophysiological recordings revealed that the
brain electrical activity is often organized in rhythmic patterns, known as neuronal
oscillations. Recently, it was discovered that ...
