1. Temporomandibular inflammation mobilizes parvalbumin and FosB/deltaFosB neurons of amygdala and dorsal raphe
Pathophysiological mechanisms involved in orofacial pain and their relationship with emotional disorders have emerged as an important research area for multidisciplinary studies. In particular, temporomandibular disorders (TMD) have been evaluated clinically from both physiological and psychological perspectives. We hypothesized that an altered neuronal acti

2. ATUAÇÃO DO NÚCLEO INCERTUS NA AQUISIÇÃO E EXTINÇÃO DE MEMÓRIAS DE MEDO CONDICIONADO. / CORE PERFORMANCE IN THE ACQUISITION AND EXTINCTION INCERTUS OF MEMORIES OF FEAR CONDITIONING.
A pesquisa dos mecanismos neurais relacionados à formação das emoções tem crescido nos últimos anos. O medo é um comportamento originado em resposta aos perigos enfrentados pelos animais, tendo sua origem nas reações defensivas exibidas quando da exposição a estímulos ameaçadores. A memória do medo ajuda os animais e os seres humanos a reconhec

3. Involvement of NK-1 receptors of the basolateral and central nuclei of the amygdala in the defensive behavior of rats / Participação dos receptores NK-1 dos núcleos basolateral e central da amígdala no comportamento defensivo de ratos
A substantial body of evidence obtained in the last decade demonstrated that the Substance P (SP) is an important mediator of the affective and emotional behaviors. SP is a pro-aversive compound when microinjected within the dorsal periaqueductal gray (dPAG). These effects are mediated by the type 1 neurokininergic receptors (NK-1), since the defensive behav

4. Role of the amygdala in the reinforcement omission effect
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 involved in motivational components related to reinforcement value, whereas the central nucleus of the amygdala is involved in the processi

5. A participação de diferentes sistemas neuromodulatórios no hipocampo, núcleo basolateral da amígdala e córtex pré-frontal ventromedial na extinção de memórias aversivas
Extinction consists of the learned inhibition of retrieval of previously acquired memory. Many forms of learning are modulated by ¿-noradrenergic, D1-dopaminergic and H2-histaminergic receptors on ventromedial prefrontal cortex (vmPFC), basolateral amygdala (BLA) and dorsal hippocampus. Therefore, the aim of this work was investigated the modulation of aver

6. Enhancement of basolateral amygdaloid neuronal dendritic arborization following Bacopa monniera extract treatment in adult rats
OBJECTIVE: In the ancient Indian system of medicine, Ayurveda, Bacopa monniera is classified as Medhya rasayana, which includes medicinal plants that rejuvenate intellect and memory. Here, we investigated the effect of a standardized extract of Bacopa monniera on the dendritic morphology of neurons in the basolateral amygdala, a region that is concerned with

7. Towards a translational model of panic attack
About 20 years ago, Deakin and Graeff proposed that whereas generalized anxiety disorder is produced by the overactivity of 5-HT excitatory projections from dorsal raphe nucleus to the areas of prefrontal cortex and amygdala which process distal threat, panic attacks are a dysfunction of 5-HT inhibitory projections from dorsal raphe nucleus to the dorsal per

8. Increased training prevents the impairing effect of intra-amygdala infusion of the non-NMDA receptor antagonist CNQX on inhibitory avoidance expression
Intra-amygdala infusion of the non-N-methyl-D-aspartate (NMDA) receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) prior to testing impairs inhibitory avoidance retention test performance. Increased training attenuates the impairing effects of amygdala lesions and intra-amygdala infusions of CNQX. The objective of the present study was to determi

9. Involvement of dopaminergic receptors of ventral tegmental area and basolateral amygdala in the acquisition and expression of conditioned fear / Envolvimento de receptores dopaminérgicos da área tegmental ventral e do complexo basolateral da amígdala na aquisição e na expressão do medo condicionado

10. Metabolic Approach to Evaluate Neuroprotection Promoted by A1 Adenosine Agonist in Pilocarpine-induced Epilepsy. / Abordagem Metabólica na Avaliação da Neuroproteção Promovida pelo Agonista Adenosinérgico A1 no Modelo de Epilepsia Induzida por Pilocarpina.
It is well known that the mismatch between local cerebral glucose utilization (LCGU) and local cerebral blood flow (LCBF) are frequently associated with seizure-induced neuronal damage in adult animal. This study was performed to verify if the neuroprotective effect of adenosinergic A1 receptor agonist R-Pia injected prior to pilocarpine could modulate LCGU

11. The inactivation of the basolateral nucleus of the rat amygdala has an anxiolytic effect in the elevated T-maze and light/dark transition tests
Pharmacological evidence indicates that the basolateral nucleus of the amygdala (BLA) is involved in the mediation of inhibitory avoidance but not of escape behavior in the elevated T-maze test. These defensive responses have been associated with generalized anxiety disorder (GAD) and panic disorder, respectively. In the present study, we determined whether

12. Infusions of AP5 into the basolateral amygdala impair the formation, but not the expression, of step-down inhibitory avoidance
We evaluated the effects of infusions of the NMDA receptor antagonist D,L-2-amino-5-phosphonopentanoic acid (AP5) into the basolateral nucleus of the amygdala (BLA) on the formation and expression of memory for inhibitory avoidance. Adult male Wistar rats (215-300 g) were implanted under thionembutal anesthesia (30 mg/kg, ip) with 9.0-mm guide cannulae aimed
