1. Applicability of an immersive virtual reality system to assess egocentric orientation of older adults
Resumo Antecedentes A orientação espacial é um domínio cognitivo frequentemente comprometido em pacientes com doença de Alzheimer (DA) e pode ser uma das suas primeiras manifestações clínicas. Alguns estudos demonstraram que a integração alocêntrica com informações espaciais egocêntricas parece prejudicada nessa patologia. Não há um consenso

2. Floor Maze Test como preditor de declínio cognitivo em idosos residentes de instituições de longa permanência
RESUMO Objetivo Pesquisas em instituições de longa permanência para idosos (ILPI) mostram uma associação entre o aumento de risco de declínio cognitivo e o comprometimento das habilidades de navegação espacial dos idosos. A navegação espacial pode ser definida como uma habilidade complexa, que depende de funções cognitivas e motoras, emergindo

3. Anxiolytic-like and proneurogenic effects of Trichilia catigua ethyl-acetate fraction in mice with cerebral ischemia
Abstract Trichilia catigua A. Juss., Meliaceae, known as "catuaba" in Brazil, has been popularly used as a tonic for fatigue, impotence and memory deficits. Previously, we have demonstrated that T. catigua ethyl-acetate fraction exerted antidepressive-like effects in mice. Affective-like symptoms are also well recognized outcome of cerebral ischemia in clini

4. Effect of ethanol Adiantum capillus-veneris extract in experimental models of anxiety and depression
Depression is one of the most common psychiatric disorders with a prevalence of 15%-25%. Monoamine aminotransferases, in particular, norepinephrine, serotonin, and dopamine, change in the brain of depressed people. Adiantum capillus-veneris is one of the species of the maidenhair fern genus that have traditionally been used to treat cough, cold symptoms, and

5. Oxiracetam ameliorates cognitive deficits in vascular dementia rats by regulating the expression of neuronal apoptosis/autophagy-related genes associated with the activation of the Akt/mTOR signaling pathway
Oxiracetam (ORC) is a commonly used nootropic drug for improving cognition and memory impairments. The therapeutic effect and underlying mechanism of ORC in vascular dementia (VaD) treatment remain unknown. In this study, 3-month-old male Sprague-Dawley rats with permanent bilateral common carotid artery occlusion-induced VaD were treated orally with low (10

6. The elevated gradient of aversion: a new apparatus to study the rat behavior dimensions of anxiety, fear, and impulsivity
Few behavioral tests allow measuring several characteristics and most require training, complex analyses, and/or are time-consuming. We present an apparatus based on rat exploratory behavior. Composed of three different environments, it allows the assessment of more than one behavioral characteristic in a short 3-min session. Factorial analyses have defined

7. Small-scale environmental enrichment and exercise enhance learning and spatial memory of Carassius auratus, and increase cell proliferation in the telencephalon: an exploratory study
Carassius auratus is a teleost fish that has been largely used in behavioral studies. However, little is known about potential environmental influences on its performance of learning and memory tasks. Here, we investigated this question in C. auratus, and searched for potential correlation between exercise and visuospatial enrichment with the total number of

10. Relationship Between the Anxious Symptoms and the Neurotransmitter in Parkinson's Mice with Different Dosages of MPTP
ABSTRACT This study aims to explore the relationship between the anxious symptoms and the impairment of 5-hydroxytryptamine system in PD mice induced by different dosages of MPTP. The mice from the three model groups, the low-dose, dose and high-dose group, took longer time in the dark box than those in the control group (P<0.05). However, no statistically s

11. Adrenergic receptor β3 is involved in the memory consolidation process in mice
Attention and emotion have a positive impact on memory formation, which is related to the activation of the noradrenergic system in the brain. The hippocampus and amygdala are fundamental structures in memory acquisition, which is modulated by noradrenaline through the noradrenergic receptors. Pharmacological studies suggest that memory acquisition depends o

12. An ontogenic study of the behavioral effects of chronic intermittent exposure to ayahuasca in mice
Ayahuasca is a beverage obtained from decoctions of the Banisteriopsis caapi plus Psychotria viridis. In religious contexts, ayahuasca is used by different age groups. However, little is known of the effects of ayahuasca during ontogenic development, particularly with regard to the functional characteristics of the central nervous system. Animal models are u
