Arginine vasotocin, the social neuropeptide of amphibians and reptiles
(2017)
Arginine vasotocin (AVT) is the non-mammalian homolog of arginine vasopressin (AVP) and, like vasopressin, serves as an important modulator of social behavior in addition to its peripheral functions related to osmoregulation, ...
The activation of metabotropic glutamate 5 receptors in the rat ventral tegmental area increases dopamine extracellular levels
(2017)
The mesocorticolimbic circuit projects to the prefrontal cortex, hippocampus, amygdala, and nucleus accumbens, among others, and it originates in the dopaminergic neurons of the ventral tegmental area (VTA). The VTA receives ...
Molecular signatures and mechanisms of long-lasting memory consolidation and storage
(Academic Press Inc Elsevier Science, 2013-11)
A body of evidence emerged in the last decade regarding late posttraining memory processing. Most of this new information comes from aversively motivated learning tasks that mainly depend on hippocampus, amygdala and insular ...
Phantom percepts: Tinnitus and pain as persisting aversive memory networks
(National Academy of Sciences, 2011-05)
Phantomperception refers to the conscious awareness of a percept in the absence of an external stimulus. On the basis of basic neuroscience on perception and clinical research in phantom pain and phantom sound, we propose ...
Análise da adversidade no processo de extinção em diferentes momentos de uma cadeia comportamental.
(Universidade Federal de Minas GeraisUFMG, 2015-03-13)
This project aims to design a study about the aversive effect of extinction at different times of a behavioral chain, analyzing the activation of c-Fos gene in the region of the prefrontal cortex, Hypothalamus and Amygdala ...
Stress-induced cross-sensitization to amphetamine is related to changes in the dopaminergic system
(Springer Wien, 2012-04-01)
Repeated stress engenders behavioral sensitization. The mesolimbic dopamine system is critically involved in drug-induced behavioral sensitization. In the present study we examined the differences between adolescent and ...
Water deprivation-induced sodium appetite
(Pergamon-Elsevier B.V. Ltd, 2010-07-14)
A water deprived animal that ingests only water efficiently corrects its intracellular dehydration, but remains hypovolemic, in negative sodium balance, and with high plasma renin activity and angiotensin II. Therefore, ...
[Differential effect of left and right temporal lobectomy on emotional recognition and experience in patients with epilepsy]
(2006)
INTRODUCTION: Temporal lobe and amygdala are structures that participate in emotional processing. The purpose of this study was to determine the differential effect of left (LTL) and right (RTL) temporal lobectomy on ...
A lesion model of envy and Schadenfreude: legal deservingness and moral,dimensions as revealed by neurodegeneration.
The study of moral emotions (i.e. Schadenfreude and envy) is critical to understand the ecological complexity of everyday interactions between cognitive, affective, and social cognition processes. Most previous studies in ...
