1. Influência da musicalização infantil nas habilidades auditivas de pré-escolares
RESUMO Objetivo Verificar a associação entre musicalização infantil e habilidades auditivas de ordenação temporal e localização sonora em pré-escolares de 5 e 6 anos. Métodos Participaram do estudo 60 crianças de ambos os sexos, de 5 anos a 6 anos e 11 meses, sendo 30 do grupo com treinamento musical e 30 do grupo sem treinamento musical. Os par

2. Temporal Resolution Ability in Students with Dyslexia and Reading and Writing Disorders
Introduction The Gaps-in-Noise (GIN) test assesses the hearing ability of temporal resolution. The development of this ability can be considered essential for learning how to read. Objective Identify temporal resolution in individuals diagnosed with reading and writing disorders compared with subjects with dyslexia. Methods A sample of 26 subjects of

3. Correlação entre atrofia hipocampal e déficit de memória em pacientes com epilepsia de lobo temporal mesial / Correlation between hippocampal atrophy and memory deficits in patients with mesial temporal lobe epilepsy
Mesial Temporal Lobe Epilepsy (MTLE) is the most common focal epilepsy in adults and is usually associated with hippocampal atrophy (HA) which is recognized by highresolution magnetic resonance imaging (MRI). It consists of a syndrome that is often refractory to clinical treatment and patients may have memory deficits due to hippocampal system damage, howeve

4. Uma arquitetura híbrida aplicada em problemas de aprendizagem por reforço / A hybrid architecture to address reinforcement learning problems
With the evergrowing use of cognitive systems in various applications, it has been created a high expectation and a large demand for machines more and more autonomous, intelligent and creative in real world problem solving. In several cases, the challenges ask for high adaptive and learning capability. This work deals with the concepts of reinforcement learn

5. MP-Draughts - Um Sistema Multiagente de Aprendizagem Automática para Damas Baseado em Redes Neurais de Kohonen e Perceptron Multicamadas
O objetivo deste trabalho é propor um sistema de aprendizagem de Damas, o MPDraughts (MultiPhase- Draughts): um sistema multiagentes, em que um deles - conhecido como IIGA (Initial/Intermediate Game Agent)- é desenvolvido e treinado para ser especializado em fases iniciais e intermediárias de jogo e os outros 25 agentes, em fases finais. Cada um dos agent

6. Organização temporal em processos de condicionamento classico aversivo e na expressão da proteina Zenk no hipocampo de pombos (C. livia) / Temporal organization of classical aversive conditioning processes and expression of Zenk protein in the hippocampus of pigeons (C. livia)
Part of the knowledge about the mechanisms and neural basis of learning, memory and amnesia is based on the investigation of neural correlates of the behavior of non human animals in aversive situations. Moreover, many studies suggest that these behavioral processes are affected by the circadian timing system. The procedures of classical aversive conditionin

7. Conservação do mico-leão preto (Leontophitecus chrysopygus) : tres tipos de manejo avaliados atraves da ecologia e comportamento
This study had the objective to carry out three different types of movements of black lion tamarin (Leontopithecus chrysopygus) individuals (three kinds of management) and to evaluate them through behavioral and ecological parameters for the species. The hypothesis was that if the managed animals showed the same behavioral and ecological tendencies of non-ma

8. Modelação temporal de processos de aprendizagem : Implicações praticas e teoricas
Studies that analyze a temporal variation in learning and memory processes are relatively scattered and inconsistent, mainly due to the lack of systematic methods and specifications of the necessary controls that would allow the dissection of a temporal component in the learning process per se. Here we analyze the difficulties of this kind of study and sugge

9. Variação circadiana na habituação da resposta exploratoria a estimulos sonoros em pombos (Columba livia), submetidos a condições de claro-escuro e de claro constante
The present work investigated habituation learning to acoustic stimulation in the context of temporal organization of behavior. The process of habituation of the exploratory responses to sound was analvsed in three experiments. The main purpose of these experiments was the analysis of these responses as function of the time of habituation sessions, i.e., mor

10. Learning about pain: The neural substrate of the prediction error for aversive events
Associative learning is thought to depend on detecting mismatches between actual and expected experiences. With functional magnetic resonance imaging (FMRI), we studied brain activity during different types of mismatch in a paradigm where contrasting-colored lights signaled the delivery of painful heat, nonpainful warmth, or no stimulation. When painful heat

11. The role of presynaptic activity in monocular deprivation: Comparison of homosynaptic and heterosynaptic mechanisms
Although investigations in computational neuroscience have been extensive, the opportunity (that has made such a marked difference in physical sciences) to test detailed and subtle quantitative consequences of a theory against experimental results is rare. In this paper, we outline a testable consequence of two contrasting theories of synaptic plasticity app

12. Deficits in speech perception predict language learning impairment
Specific language impairment (SLI) is one of the most common childhood disorders, affecting 7% of children. These children experience difficulties in understanding and producing spoken language despite normal intelligence, normal hearing, and normal opportunities to learn language. The causes of SLI are still hotly debated, ranging from nonlinguistic deficit
