13. Staging and neuroprogression in bipolar disorder: a systematic review of the literature
INTRODUCTION: The use of clinical staging models is emerging as a novel and useful paradigm for diagnosing severe mental disorders. The term "neuroprogression" has been used to define the pathological reorganization of the central nervous system along the course of severe mental disorders. In bipolar disorder (BD), neural substrate reactivity is changed by r

14. The Val66Met polymorphism at the BDNF gene does not influence Wisconsin Card Sorting Test results in children and adolescents with bipolar disorder
OBJECTIVES: To assess the role of the Val66Met polymorphism at the brain-derived neurotrophic factor (BDNF) gene on the performance of children and adolescents with bipolar disorder [juvenile bipolar disorder (JBD)] on the Wisconsin Card Sorting Test (WCST). METHODS: Children and adolescents were assessed by the K-SADS-PL and a clinical evaluation for BD and

15. Contributions of animal models to the study of mood disorders
Mood disorders are a leading cause of morbidity and mortality, yet their underlying pathophysiology remains unclear. Animal models serve as a powerful tool for investigating the neurobiological mechanisms underlying psychiatric disorders; however, no animal model developed to date can fully mimic the “corresponding” human psychiatric disorder. In this sc

16. Comportamento suicida no transtorno afetivo bipolar e características sociodemográficas, clínicas e neuroanatômicas associadas
CONTEXTO: Pacientes com transtorno bipolar possuem risco maior de suicídio, quando comparados com a população geral e com outros transtornos psiquiátricos. Este artigo tem como objetivo revisar os aspectos sociodemográficos, clínicos e neuroanatômicos associados ao comportamento suicida em pacientes com transtorno bipolar com história de tentativa de

17. Uma abordagem neurofisiológica da acetilcolina em plantas de milho hidratadas e sob condições de estresse hídrico / A neurophysiological approach to acetylcholine in maize plants hydrated and under water stress conditions
The occurrence of action potential and neurotransmitters, the major components of animal nervous system, in plants, bacteria and fungi, shows the universality of signaling principles and information transmission in the way of chemical and electrical signals in all organisms. These study topics, along with plant intelligence and vesicular-based auxin transpor

18. Dynamics of mother-pup interactions: tradeoff between environment and physiology
The emergence and maintenance of maternal behavior are under the influence of environmental cues such as light and dark periods. This article discusses the characteristic neurobiology of the behavioral patterns of lactating rats. Specifically, the hormonal basis and neurocircuits that determine whether mother rats show typical sequential patterns of behavior

20. Animal models of prenatal immune challenge and their contribution to the study of schizophrenia: a systematic review
Prenatal immune challenge (PIC) in pregnant rodents produces offspring with abnormalities in behavior, histology, and gene expression that are reminiscent of schizophrenia and autism. Based on this, the goal of this article was to review the main contributions of PIC models, especially the one using the viral-mimetic particle polyriboinosinic-polyribocytidyl

21. Utilização de redes neurais de Spikes para tarefas de navegação de agentes robóticos autônomos
Detectar e prevenir possíveis colisões é um dos aspectos mais importantes na robótica móvel. Esta tarefa, embora aparente facilidade quando executada por seres vivos, mantêm sua dificuldade quando modelada e executada por agentes robóticos autônomos. Além disso, roboticistas e pesquisadores têm sempre encontrado na natureza uma fonte inesgotável d

22. Efeito ansiolítico do ondansetron, antagonista dos receptores 5-HT3, injetado na amídala de camundongos submetidos à exposição e reexposição no labirinto em cruz elevado
Against of stimuli that are dangerous, animals manifest defense reactions that cause fear and anxiety. These stimuli activate the serotonergic system, which sends projections to structures involved in defense mechanisms such as the septum, hypothalamus, hippocampus, amygdala and periaqueductal gray modulates the behavioral changes that can be characterized a

23. Psychoanalytic treatment: a neurobiological view
We present a review of several hypotheses concerning the possible neurobiological correlates of the main processes involved in analytic therapy. Attachment theory may represent an interesting link between psychoanalysis and neurobiology. According to Bowlby's conception, interactions with parental figures during infancy lead to the formation of an "internal

24. Effects of chronic corticosterone and imipramine administration on panic and anxiety-related responses
It is known that chronic high levels of corticosterone (CORT) enhance aversive responses such as avoidance and contextual freezing. In contrast, chronic CORT does not alter defensive behavior induced by the exposure to a predator odor. Since different defense-related responses have been associated with specific anxiety disorders found in clinical settings, t
