Central, but not basolateral, amygdala involvement in the anxiolytic-like effects of midazolam in rats in the elevated plus maze
(SAGE PUBLICATIONS LTDLONDON, 2012)
The role of the amygdala in the mediation of fear and anxiety has been extensively investigated. However, how the amygdala functions during the organization of the anxiety-like behaviors generated in the elevated plus maze ...
Abnormal Left and Right Amygdala-Orbitofrontal Cortical Functional Connectivity to Emotional Faces: State Versus Trait Vulnerability Markers of Depression in Bipolar Disorder
(ELSEVIER SCIENCE INC, 2010)
Background: Amygdala-orbitofrontal cortical (OFC) functional connectivity (FC) to emotional stimuli and relationships with white matter remain little examined in bipolar disorder individuals (BD). Methods: Thirty-one BD ...
Role of the amygdala in the reinforcement omission effect
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2012)
The reinforcement omission effect (ROE) has been attributed to both motivational and attentional consequences of surprising reinforcement omission. Recent evidence suggests that the basolateral complex of the amygdala is ...
Induction of Zenk protein expression within the nucleus taeniae of the amygdala of pigeons following tone and shock stimulation
(Associação Brasileira de Divulgação Científica, 2011)
In this study, we evaluated the expression of the Zenk protein within the nucleus taeniae of the pigeon’s amygdala (TnA) after training in a classical aversive conditioning, in order to improve our understanding of ...
Similar anxiolytic-like effects following intra-amygdala infusions of benzodiazepine receptor agonist and antagonist: Evidence for the release of an endogenous benzodiazepine inverse agonist in mice exposed to elevated plus-maze test
(Elsevier B.V., 2009-04-24)
Previous studies have demonstrated that microinjections of midazolam, a benzodiazepine receptor agonist, into the amygdala produce anxiolytic-like effects in elevated plus-maze (EPM)-naive rodents. However, systemic or ...
The importance of accurate anatomic assessment for the volumetric analysis of the amygdala
(Associação Brasileira de Divulgação Científica, 2005)
EFFECT OF ELECTROLYTIC AND CHEMICAL LESION BY IBOTENIC ACID OF THE AMYGDALA ON SALT INTAKE
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-12-01)
Sodium chloride intake was studied in male Holtzman rats weighing 250-300 g submitted to electrolytic and chemical lesion of the cell bodies, not fibers of the amygdaloid complex. Sodium chloride (1.5%) intake increased ...
Amygdala hyperactivation in untreated depressed individuals
(ELSEVIER IRELAND LTD, 2009)
The amygdala participates in the detection and control of affective states, and has been proposed to be a site of dysfunction in affective disorders. To assess amygdala processing in individuals with unipolar depression, ...
