Do spatial and recognition memories have a lateralized processing by the dorsal hippocampus CA3?
(2022-01-07)
The present study evaluated the function of the right and left CA3 of the dorsal hippocampus (dHPC) in the processing of (i) recognition memory, (ii) recent and remote spatial memory, (iii) working memory and (iv) navigation ...
Dorsal hippocampus plays a causal role in context-induced reinstatement of alcohol-seeking in rats
(2021-02-01)
Drug addiction is a chronic mental disorder characterized by frequent relapses. Contextual cues associated with drug use to play a critical causal role in drug-seeking behavior. The hippocampus has been implicated in ...
Envolvimento da neurotransmissão nitrérgica no hipocampo dorsal no controle da função cardiovascular e das respostas autônomas e comportamentais ao estresse social crônico
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2018-08-17)
The hippocampus is part of the limbic system, and is directly involved in cognitive processes, anxiety-related defensive behaviors, stress responses, and the neurobiology of depression. Some studies have also reported a ...
The influence of sex and chronic restraint stress on transcriptional and post-transcriptional regulations on the rat dorsal and ventral hippocampus
(Universidad de Chile, 2022)
Our increasing understanding of sex has unveiled its relevance for health and disease.
Importantly, the search of the molecular bases that act as the foundations for sex differences
in health and disease may provide novel ...
Chronic stress triggers expression of immediate early genes and differentially affects the expression of AMPA and NMDA subunits in dorsal and ventral hippocampus of rats
(Frontiers media SA, 2017)
Previous studies in rats have demonstrated that chronic restraint stress triggers anhedonia, depressive-like behaviors, anxiety and a reduction in dendritic spine density in hippocampal neurons. In this study, we compared ...
Chronic Stress Triggers Expression of Immediate Early Genes and Differentially Affects the Expression of AMPA and NMDA Subunits in Dorsal and Ventral Hippocampus of Rats
(Frontiers Media, 2017-08)
Previous studies in rats have demonstrated that chronic restraint stress triggers anhedonia, depressive-like behaviors, anxiety and a reduction in dendritic spine density in hippocampal neurons. In this study, we compared ...
Motor effects of electrical and cholinergic stimulation of the cat's dorsal hippocampus
(1984)
The effect of electrical stimulation of the dorsal hippocampus was studied in 17 adult cats with implanted electrodes as well as the effects of carbachol and dioxolane in a group of ten adult cats with a cannula and ...
Role of hippocampal nitrergic neurotransmission in behavioral and cardiovascular dysfunctions evoked by chronic social stress
(2020-01-01)
Increased nitric oxide (NO) levels have been identified in the hippocampus of animals subjected to social isolation. However, a role of this change in behavioral and physiological changes evoked by isolation has never been ...
Role of cholinergic, opioidergic and GABAergic neurotransmission of the dorsal hippocampus in the modulation of nociception in guinea pigs
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aims: Several physiological, pharmacological and behavioral lines of evidence suggest that the hippocampal formation is involved in nociception. The hippocampus is also believed to play an important role in the affective ...
