25. Conspecific and heterospecific alarm substances induce behavioral responses in juvenile catfish Rhamdia quelen
RESUMO O reconhecimento das informações químicas indicando a presença de predadores é muito importante para a sobrevivência da presa. Neste estudo foi testada a resposta comportamental anti-predação de juvenis de jundiás (Rhamdia quelen) a substâncias liberadas por dois predadores potenciais, Hoplias malabaricus e a cobra Helicops infrataeniatus, e

26. Auditory Processing Assessment in Children with Attention Deficit Hyperactivity Disorder: An Open Study Examining Methylphenidate Effects
Abstract Introduction Children with Attention Deficit Hyperactivity Disorder can present Auditory Processing (AP) Disorder. Objective The study examined the AP in ADHD children compared with non-ADHD children, and before and after 3 and 6 months of methylphenidate (MPH) treatment in ADHD children. Methods Drug-naive children diagnosed with ADHD combine

27. 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

28. Critical neuropsychobiological analysis of panic attack- and anticipatory anxiety-like behaviors in rodents confronted with snakes in polygonal arenas and complex labyrinths: a comparison to the elevated plus- and T-maze behavioral tests
Objective: To compare prey and snake paradigms performed in complex environments to the elevated plus-maze (EPM) and T-maze (ETM) tests for the study of panic attack- and anticipatory anxiety-like behaviors in rodents. Methods: PubMed was reviewed in search of articles focusing on the plus maze test, EPM, and ETM, as well as on defensive behaviors displaye

29. Economic Incentives or Communication: How Different Are their Effects on Trust
Abstract This study investigates the effects of economic incentives and communication on the cognitive and behavioral responses after an alleged trust violation. We argue that these responses depend on the type of solution used to foster cooperation between agents. On the cognitive level, we compare the effects that structural (economic incentives) and motiv

30. Relationships between physiological and behavioral responses of goat bucks in mating season
ABSTRACT The objective of this study was to determine the sexual parameters in young bucks with different sexual activity and the effect of experience (age) on sexual parameters in bucks. Fifteen young, sexually inexperienced (SI) and five adult, sexually experienced (SE) Saanen × Hair goat crossbred bucks were used in this study. Bucks were individually ex

31. Dependencia térmica de la salamandra endémica de Colombia Bolitoglossa ramosi (Caudata, Plethodontidae)
ABSTRACT Environmental temperature is a determining factor in the physiological and behavioral processes of amphibians because they are ectotherms and consequently depend on external heat sources to achieve optimal body temperatures. The aim of this study was to determine the thermal dependence of the Colombian endemic salamander Bolitoglossa ramosi Brame &

32. Behavior of immunocastrated pigs
ABSTRACT The objective of this study was to evaluate the behavior of immunocastrated male pigs compared with females and castrated males during the period before and after full immunization. A total of 30 animals were divided into three treatments, with ten animals in each (females, barrows, and immunocastrated males). The experiment was divided into three p

33. Behavioral fever response in Rhodnius prolixus (Reduviidae: Triatominae) to intracoelomic inoculation of Trypanosoma cruzi
Abstract: INTRODUCTION: Behavioral fever is a response to infections with microorganisms observed in some poikilothermic animals. Rhodnius prolixus is involved in the transmission of two parasites: Trypanosoma cruzi (pathogenic for humans and transmitted in feces) and Trypanosoma rangeli (non-pathogenic for humans, pathogenic for Rhodnius and transmitted b

34. Phenotypic plasticity associated to environmental hypoxia in the neotropical serrasalmid Piaractus mesopotamicus (Holmberg, 1887) (Characiformes: Serrasalmidae)
ABSTRACT Many South American characid fishes develop reversible dermal protuberances in the jaws to optimize aquatic surface respiration (ASR) during hypoxia. To date, basic aspects of this adaptation remain unknown, mainly due to the scarcity of experimental studies. In laboratory experiments, we determined time necessary for the complete formation and reve

35. Selective 5-HT7 receptor agonists LP 44 and LP 211 elicit an analgesic effect on formalin-induced orofacial pain in mice
ABSTRACT The most recently identified serotonin (5-HT) receptor is the 5-HT7 receptor. The antinociceptive effects of a 5-HT7 receptor agonist have been shown in neuropathic and inflammatory animal models of pain. A recent study demonstrated the functional expression of 5-HT7 receptors in the substantia gelatinosa (SG) of the trigeminal subnucleus caudalis,

36. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have
