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. Caracteres importantes na identificação de espécies de Ludwigia (Onagraceae) ocorrentes no Recôncavo da Bahia, Brasil
Resumo Na flora aquática do Brasil, o gênero Ludwigia apresenta ca. 48 espécies. A maioria das espécies de Ludwigia é anfíbia, apresentando uma grande plasticidade fenotípica, o que torna sua identificação complexa. O objetivo deste trabalho foi realizar um levantamento taxonômico e analisar caracteres diagnósticos na delimitação das espécies d

3. Tryptophan overloading activates brain regions involved with cognition, mood and anxiety
ABSTRACT Tryptophan is the only precursor of serotonin and mediates serotonergic activity in the brain. Previous studies have shown that the administration of tryptophan or tryptophan depletion significantly alters cognition, mood and anxiety. Nevertheless, the neurobiological alterations that follow these changes have not yet been fully investigated. The ai

5. Fos expression in the prefrontal cortex and mesencephalic dorsal raphe nucleus in lactating rats after social instigation
Females are often less aggressive than males, but they exhibit high levels of agonistic behavior against an intruder in the area of the nest during lactation. This behavior is referred to as maternal aggression. In rats, maternal aggressive behavior occurs more often from postpartum day 3 (PPD 3) to PPD 12. Social instigation is an experimental protocol used

6. Importância do tecido adiposo marrom na ativação da termogênese induzida pela injeção central do C75, um inibidor da ácido graxo sintase / Importance of brown adipose tissue in the activation of thermogenesis induced by central injection of C75, a fatty acid synthase inhibitor
C75, a synthetic inhibitor of fatty acid synthase, causes anorexia and weight loss in rodents, but the underlying mechanisms are not totally known. Thus, the hypothesis tested in this work was that brown adipose tissue (BAT), an organ with important role for control of thermogenesis, could be involved in the anti-obesity effects of fatty acid synthase inhibi

7. O bloqueio dos receptores 5-HT2 da substância cinzenta periaquedutal suprime o efeito ansiolítico resultante do antagonismo dos receptores 5-HT1A do núcleo mediano da rafe em camundongos / Blockade of 5-HT2 receptors in the periaqueductal grey matter (PAG) abolishes the anxiolytic-like effect of 5-HT1A receptor antagonism in the median raphé nucleus in mice. 2011.
Várias evidências apontam o envolvimento de neurônios serotoninérgicos do núcleo mediano da rafe (NMnR) na ansiedade. Sabe-se que o bloqueio dos autorreceptores somatodendríticos dos núcleos da rafe aumenta a taxa de disparo dos neurônios serotoninérgicos, promovendo a liberação de serotonina em sítios pós-sinápticos como amígdala, hipocampo e

8. 5-HT1A autoreceptor modulation of locomotor activity induced by nitric oxide in the rat dorsal raphe nucleus
The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhi

9. Rate and sites of water uptake by bean seed as affected by high temperature stress.
The entry site and rate of water uptake were verified in two meso-american bean cultivars Perolo (carioca type) and BRS-Valente (black) produced with and without high temperature stress. To study the principal water entry site during soaking the seed size and sealed with acrylic glue: 1. micropyle; 2. raphe; 3. hilum; 4. micropyle + rate + hilum and 5. check

10. Delimitação dos grupamentos serotoninérgicos/núcleos da rafe do mocó (kerodon rupestris): citoarquitetura e imunoistoquímica para serotonina
A serotonina ou 5-hidroxitriptamina (5-HT) é uma substância encontrada em muitos tecidos do organismo, inclusive no sistema nervoso como neurotransmissor, onde pode exercer ações pós-sinápticas variadas. Dentro do neuro-eixo, a localização dos neurônios 5-HT é quase absoluta nos núcleos da rafe do tronco encefálico, de tal maneira que 5-HT neuron

11. Serotonin and circadian rhythms
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures. Pathways receive and transmit environmental cues to the central oscillat

12. 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
