Dose-response effects of systemic anandamide administration in mice sequentially submitted to the open field and elevated plus-maze tests
(Associação Brasileira de Divulgação Científica, 2009)
The endocannabinoid system is involved in the control of many physiological functions, including the control of emotional states. In rodents, previous exposure to an open field increases the anxiety-like behavior in the ...
Stimulation of 5-HT1A or 5-HT2A receptors in the ventrolateral periaqueductal gray causes anxiolytic-, but not panicolytic-like effect in rats
(ELSEVIER SCIENCE BV, 2009)
Evidences from studies using electrical or chemical stimulation of the midbrain periaqueductal gray (PAG) suggest that whereas the dorsal PAG is critical for the regulation of panic-related defensive behaviors, the ...
Resistance to fear memory destabilization triggers exaggerated emotional-like responses following memory reactivation
(Pergamon-Elsevier Science Ltd, 2019-07)
Fear memory reactivation does not always lead to memory destabilization-reconsolidation. For instance, fear memories formed following withdrawal from chronic ethanol consumption or a stressful event are less likely to ...
Sucrose exposure in juvenile rats produces long-term changes in fear memory and anxiety-like behavior
(Pergamon-Elsevier Science Ltd, 2019-06)
Sugar consumption has increased dramatically in our society, a phenomenon that is primarily associated with obesity and diabetes appearance. However, whether this overconsumption of sugar has an impact on the developing ...
Salicylate generates anxiety-like behavior and type 2 theta oscillation in the ventral hippocampus of mice
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2016-09-20)
Salicylate, the main compound of many medications as Aspirin, is known to cause
tinnitus if consumed in high doses or in a chronic way (for the treatment of osteoporosis, for
example). Tinnitus is the hearing or perception ...
Effects of angiotensin (5-8) microinfusions into the ventrolateral periaqueductal gray on defensive behaviors in rats
(Elsevier B.V., 2013-11-01)
Peptides of the renin-angiotensin system modulate blood pressure and hydro-electrolyte composition. Angiotensin (Ang) receptors are localized in brain areas related to the regulation of autonomic and endocrine control and ...
