Modulación de la actividad del sistema glucocorticoide por parte del receptor CB1 cannabinoide
(2019-03-27)
Los procesos moleculares que subyacen la formación de memorias a largo plazo involucran la activación de cascadas de señalización que transmiten las señales inducidas por la acción de neurotransmisores en la membrana celular ...
Estresse, após a aprendizagem, reduz a persistência de uma memória aversiva em ratos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2019)
D2 dopamine receptor regulation of learning, sleep and plasticity
(Elsevier, 2015-01-16)
Dopamine and sleep have been independently linked with hippocampus-dependent learning.
Since D2 dopaminergic transmission is required for the occurrence of rapid-eye-movement (REM)
sleep, it is possible that dopamine ...
Efeitos do ambiente enriquecido sobre a memória aversiva e a imunorreatividade para ZIF-268 e tirosina hidroxilase no sistema mesocorticolímbico de ratosEffects of the enriched environment on aversive memory and immunorreactivity for ZIF-268 and tyrosine hydroxylase in the mesocorticolmmic system of rats

Estudio de las modificaciones epigeneticas inducidas en la rata por una nutrición desequilibrada durante el desarrollo perinatal
(2013-03-06)
RESUMEN: La desnutrición perinatal se ha asociado con el alto riesgo a desarrollar síndrome metabólico así como déficit en la capacidad de aprendizaje y memoria. En las ratas, una alimentación baja en proteínas durante la ...
Estudo do envolvimento do córtex perirrinal na reconsolidação da memória de reconhecimento de objetos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2019-03-14)
Consolidated memories can become labile when reactivated and, to persist, must
undergo a protein synthesis-dependent restabilization process called
reconsolidation. The perirhinal cortex (PER) regulates the flow of ...
Motor cortex stimulation inhibits thalamic sensory neurons and enhances activity of PAG neurons: Possible pathways for antinociception
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Motor cortex stimulation is generally suggested as a therapy for patients with chronic and refractory neuropathic pain. However, the mechanisms underlying its analgesic effects are still unknown. In a previous study, we ...
A BDNF sensitive mechanism is involved in the fear memory resulting from the interaction between stress and the retrieval of an established trace
(Cold Spring Harbor Lab Press, 2013-05)
The present study investigates the fear memory resulting from the interaction of a stressful experience and the retrieval of an established fear memory trace. Such a combination enhanced both fear expression and fear ...
Processamento da memória de medo: dimorfismo sexual e consolidação tardia na amígdala e no córtex pré-frontal medial
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE FISIOLOGIA E BIOFÍSICAPrograma de Pós-Graduação em Ciências Biológicas - Fisiologia e FarmacologiaUFMG, 2021-05-14)
Not all memories last for the lifetime. Generally speaking, memories with high emotional value during acquisition tend to remain accessible for longer periods. However, the mechanisms that interfere with memory endurance ...
