1. A systematic review of observational, naturalistic, and neurophysiological outcome measures of nonpharmacological interventions for autism
Objective: Naturalistic and neurophysiological assessments are relevant as outcome measures in autism intervention trials because they provide, respectively, ecologically valid information about functioning and underlying neurocognitive mechanisms. We conducted a systematic review to highlight which specific neurophysiological techniques, experimental tasks,

2. Latent class analysis of attention and white matter correlation in children with attention-deficit/hyperactivity disorder
This study aimed to explore attentional patterns among children with inattentive attention-deficit/hyperactivity disorder (ADHD-I) and children with typical development (TD), using a latent class analysis (LCA). Patterns of brain connectivity were also explored. The sample comprised 29 ADHD-I and 29 TD matched children. An LCA was conducted to reclassify sub

3. The Long-Range Memory and the Fractal Dimension: a Case Study for Alcântara
ABSTRACT: This study aimed to analyze the time series behavior of the Southern Oscillation Index through techniques using Fast Fourier Transform, computing the autocorrelation function, and the calculation of the Hurst coefficient. The methodology of Hurst Exponent calculation uses different lags, which are computed in the time series of Southern Oscillation

4. Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects
ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there

5. Comparative central effects of the aqueous leaf extract of two populations of Passiflora edulis
ABSTRACTPassiflora edulis Sims, Passifloraceae, has been used in Brazilian traditional folk medicine to the treatment of anxiety and insomnia. P. edulis is commonly known for its economic interests in Brazil. This species exhibits significant variability in the fruit rind color, then two subpopulations has been described (P. edulis fo. flavicarpa O. Deg. (PE

6. Automatic pain quantification using autonomic parameters
The objective measurement of subjective, multi-dimensionally experienced pain is a problem for which there has not been an adequate solution. Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals. Biopoten

7. Religião, espiritualidade e doença cardiovascular: pesquisa, implicações clínicas e oportunidades no Brasil
In this paper we comprehensively review published quantitative research on the relationship between religion, spirituality (R/S), and cardiovascular (CV) disease, discuss mechanisms that help explain the associations reported, examine the clinical implications of those findings, and explore future research needed in Brazil on this topic. First, we define the

8. Efeitos das contingências de reforçamento LAG e RDF sobre a variabilidade comportamental de crianças autistas / Effects of reinforcement contingencies LAG and RDF on behavioral variability of autistic children
A fim de verificar os efeitos das contingências de reforçamento LAG e RDF sobre a variabilidade comportamental de crianças autistas, estabeleceu-se na presente pesquisa dois diferentes procedimentos de ensino da variabilidade um para a contingência LAG e outro para a RDF que iniciavam com baixo requerimento de variação para a obtenção do reforço e c

9. Variabilidade comportamental e a seleção de uma sequência de baixa probabilidade inicial: comparando dois procedimentos
O objetivo do estudo foi avaliar a efetividade de dois procedimentos, Tentativa Discreta (TD) e Tentativa Discreta com Intervalo entre as Respostas (TD/IRI), na produção da variabilidade comportamental em diferentes condições (diretamente reforçada e induzida) e averiguar que condição, em cada procedimento, mais facilitaria a seleção de uma sequênc

10. Variabilidade comportamental como função de diferentes contingências de reforçamento e sua ordem de apresentação / Behavior Variability as a function of different reinforcement contingencies and their order of presentation
O presente trabalho teve por objetivo verificar experimentalmente (1) se a variabilidade do comportamento, obtida como função de contingências de reforçamento LAG n e RDF, sofre interferência da manipulação sistemática dos parâmetros n(LAG) e do limiar de reforçamento (RDF) e (2) se a história de reforçamento, estabelecida por ordem crescente, de

11. On the relationships between ultrasonic calling and anxiety-related behavior in rats
In the present review, the phenomenon of ultrasonic vocalization in rats will be outlined, including the three classes of vocalizations, namely 40-kHz calls of pups, and 22- and 50-kHz calls of juvenile and adult rats, their general relevance to behavioral neuroscience, and their special relevance to research on anxiety, fear, and defense mechanisms. Here, t

12. Hematological abnormalities and 22q11.2 deletion syndrome
The 22q11.2 deletion syndrome (22q11DS) is a common genetic disease characterized by broad phenotypic variability. Despite the small number of studies describing hematological alterations in individuals with 22q11DS, it appears that these abnormalities are more frequent than previously imagined. Thus, the objective of our study was to report on a patient wit
