Modulação colinérgica de comportamentos sociais em camundongos
(Universidade Federal de Minas GeraisUFMG, 2015-07-27)
Social behavior is essential for hierarchy, mating, territorial aggression, affiliation and parental care. Thus, the species survival depends of this behavior. However,so far, the molecular basis of social behavior has not ...
Chronic nicotine activates stress/reward-related brain regions and facilitates the transition to compulsive alcohol drinking
(Soc Neuroscience, 2015-04-15)
Alcohol and nicotine are the two most co-abused drugs in the world. Previous studies have shown that nicotine can increase alcohol drinking in nondependent rats, yet it is unknown whether nicotine facilitates the transition ...
N-Methyl-D-aspartate Glutamate Receptor Modulates Cardiovascular and Neuroendocrine Responses Evoked by Hemorrhagic Shock in Rats
(2021-01-01)
Here, we report the participation of N-methyl-D-aspartate (NMDA) glutamate receptor in the mediation of cardiovascular and circulating vasopressin responses evoked by a hemorrhagic stimulus. In addition, once NMDA receptor ...
Changes in fos expression in various brain regions during deoxycorticosterone acetate treatment: relation to salt appetite, vasopressin mRNA and the mineralocorticoid receptor
(Karger, 2001-12)
Salt appetite, a conditioning factor for hypertension and cardiovascular diseases, is produced when high doses of mineralocorticoids are given to experimental animals. A commonly used procedure to identify neuronal activation ...
GnRH neurones population in the diencephalon of the coypu (Myocastor coypus)Estudio inmunohistoquímico de la población de neuronas gnrh en el diencéfalo del coipo (Myocastor coypus)
(Sociedad Chilena de Anatomía, 2000-01)
The goal of this study was to investigate the distribution and morphology of neurones that synthesise and store gonadotrophin releasing factor (GnRH) in the diencephalon of the coypu (Myocastor coypus), a South American ...
Involvement of the prelimbic prefrontal cortex on cannabidiol-induced attenuation of contextual conditioned fear in rats
(ELSEVIER SCIENCE BV, 2010)
Rationale: Systemic administration of cannabidiol (CBD), a non-psychotomimetic component of Cannabis sativa, is able to attenuate cardiovascular and behavioral (freezing) changes induced by re-exposure to a context that ...
The medial amygdaloid nucleus is involved in the cardiovascular pathway activated by noradrenaline into the lateral septal area of rats
(WILEY-BLACKWELLHOBOKEN, 2012)
We have previously reported that noradrenaline (NA) microinjected into the lateral septal area (LSA) caused pressor and bradicardic responses that were mediated by vasopressin release into the circulation through the ...
Brain Pathways Involved in the Modulatory Effects of Noradrenaline in Lateral Septal Area on Cardiovascular Responses
(SPRINGER/PLENUM PUBLISHERSNEW YORK, 2012)
We have previously reported that stimulation of alpha-1 adrenoceptors by noradrenaline (NA) injected into the lateral septal area (LSA) of anaesthetized rats causes pressor and bradycardic responses that are mediated by ...
Neuronal NOS Inhibitor and Conventional Antidepressant Drugs Attenuate Stress-induced Fos Expression in Overlapping Brain Regions
(SPRINGER/PLENUM PUBLISHERSNEW YORK, 2012)
Recent evidence indicates that the administration of inhibitors of neuronal nitric oxide synthase (nNOS) induces antidepressant-like effects in animal models such as the forced swimming test (FST). However, the neural ...
