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. Acute physical and psychological stress effects on visceral hypersensitivity in male rat: role of central nucleus of the amygdala
ABSTRACT Objective: The aim of this study was to investigate the effects of acute physical and psychological stress and temporary central nucleus of the amygdala (CeA) block on stress-induced visceral hypersensitivity. Methods: Forty two male Wistar rats were used in this study. Animals were divided into 7 groups (n = 6); 1 - Control, 2 - physical stress,

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. Núcleo central da amígdala e Núcleo parabraquial lateral no controle da ingestão de sódio
Previous studies have shown the importance of serotonergic GABAergic and aadrenergic mechanisms of the lateral parabraquial nucleus (LBPN) in the control of sodium intake. The importance of the central nucleus of the amygdala (CeA) for sodium intake induced by different protocols was also demonstrated. Considering the studies showing reciprocal connections b

6. Temporal evaluation of c-fos expression in amygdaloid and hypothalamic areas following experimental tooth movement in rats / Avaliação temporal da expressão da proteína FOS em áreas amigdalóides e hipotalâmicas após movimentação dentária experimental em ratos
In the accomplishment of the orthodontic treatment, it is described that the pain happens immediately after the application of orthodontic forces and disappears after few days. Regarding the neural pathways involved in the sensorial mediation of the orthodontic movement (OM) few are the studies that approach this theme, and in the last decades solid founds d

7. Neuroanatomical and cellular substrates of the behavior hypergrooming induced by microinjection of oxytocin in central nucleus of amygdala, an experimental model of obsessive-compulsive disorder / Substratos neuroanatômicos e celulares do comportamento de autolimpeza exacerbada (hypergrooming) induzido pela injeção de ocitocina no núcleo central da amígdala, um modelo experimental de transtorno obsessivo-compulsivo
Oxytocin (OT) is a neurosecretory nonapeptide synthesized in hypothalamic cells that project to the neurohypophysis as well as to widely distributed sites in the central nervous system. Central OT microinjections induce a variety of cognitive, sexual, reproductive, grooming and affiliative behaviors in animals. Obsessive-compulsive disorder (OCD) includes a

8. Cholinergic-opioidergic interaction in the central amygdala induces antinociception in the guinea pig
Several studies have demonstrated the involvement of the central nucleus of the amygdala (CEA) in the modulation of defensive behavior and in antinociceptive regulation. In a previous study, we demonstrated the existence of a cholinergic-opioidergic interaction in the CEA, modulating the defensive response of tonic immobility in guinea pigs. In the present s

9. Neural correlates of food allergy: role of IgE-dependent mechanisms and sensory C-fibers / Percepção neural da alergia alimentar: envolvimento de mecanismos dependentes de IgE e das fibras nervosas do tipo C
Although many authors have considered the possibility of a direct interaction between food allergy and behavioral changes, the evidence supporting this hypothesis is elusive. Here we show that after oral OVA challenge allergic mice present higher levels of anxiety, increased serum corticosterone, and increased Fos expression in the paraventricular nucleus of

10. Neural organization of the mesencephalic system responsible for the freezing behavior. / Organização do sistema neural mesencefálico responsável pela resposta de congelamento.
Freezing to a context previously associated to footshock is attenuated by ventrolateral periaqueductal gray (vlPAG) lesion. Moreover, electrical stimulation or microinfusion of compounds that interfere with GABA neurotransmission in the dorsolateral periaqueductal gray (dlPAG) provoke freezing and escape. The present study examined the possibility of this fr

11. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

12. Origem da inervação dopaminérgica da divisão central da amígdala expandida e da concha do núcleo Acumbens no rato. / Origin of dopaminergic fibers to the central extended amygdala and nucleus accumbens shell in the rat.
A amígdala expandida central (EAc) inclui os núcleos central da amígdala (CeA), intersticial lateral da estria terminal (BSTl), intersticial do ramo posterior da comissura anterior (IPAC) e amígdala expandida sublenticular (SLEA). A EAc e a concha do acumbens possuem densa inervação dopaminérgica, implicada em processos motivacionais, e cuja origem fo
