1. Percepção da fala em crianças usuárias de implante coclear com duas estratégias de processamento do sinal do sistema HiResolution / Speech perception in children with cochlear implants with two sound processing strategy of the HiResolution system
Improvements in speech perception with cochlear implant (CI) over the years is related, among others factors, to the technological advance of the sound processing strategy. The purpose of the present study was to investigate speech perception performance in CI children, with two different Advanced Bionics sound processing strategy. Subjects were 11 prelingua

2. Integrating production and perception of secundary prominences in a dynamical perspective of rhythm / Integrando produção e percepção de proeminencias secundarias numa abordagem dinamica do ritmo da fala
The thesis investigates two main subjects: secondary stress in Brazilian Portuguese (BP) and the link between rhythm production and rhythm perception. Both subject matters are developed in light of Barbosa s (2006, 2007) coupled-oscillator model of rhythm production. Interest in secondary stress in BP is fostered by the fact that its existence, nature and di

3. Contribuição sensorial na facilitação do estímulo precedente. / Facilitation by automatic temporal expectation.
A ocorrência de um estímulo auditivo imediatamente antes de um estímulo alvo visual reduz o tempo de reação em dezenas de milisegundos, um efeito atribuído a atenção temporal automática. O presente estudo investigou se este efeito é resultante de uma facilitação de mecanismos sensoriais. Dois experimentos foram realizados. No primeiro, foi realiz

4. Papel de sinais cromáticos na identificação de parceiros sexuais em sagüi comum (callithrix jacchus)
The literature concerning color vision shows a trichromatic advantage in detecting ripe fruits and young leaves, but there are contradictory results. There is also the suggestion of this type of vision being adapted to perceive socio-sexual signals. Indeed, Old World primates utilize the skin color of conspecifics as a factor of attraction. But in New World

5. Quantitative prediction of perceptual decisions during near-threshold fear detection
A fundamental goal of cognitive neuroscience is to explain how mental decisions originate from basic neural mechanisms. The goal of the present study was to investigate the neural correlates of perceptual decisions in the context of emotional perception. To probe this question, we investigated how fluctuations in functional MRI (fMRI) signals were correlated

6. The conformation of neurotensin bound to its G protein-coupled receptor
G protein-coupled receptors (GPCRs) mediate the perception of smell, light, taste, and pain. They are involved in signal recognition and cell communication and are some of the most important targets for drug development. Because currently no direct structural information on high-affinity ligands bound to GPCRs is available, rational drug design is limited to

7. The role of nocturnal vision in mate choice: females prefer conspicuous males in the European tree frog (Hyla arborea)
Nocturnal frog species rely extensively on vocalization for reproduction. But recent studies provide evidence for an important, though long overlooked, role of visual communication. In many species, calling males exhibit a conspicuous pulsing vocal sac, a signal bearing visually important dynamic components. Here, we investigate female preference for male vo

8. Differential Recognition of Highly Divergent Downy Mildew Avirulence Gene Alleles by RPP1 Resistance Genes from Two Arabidopsis Lines
The perception of downy mildew avirulence (Arabidopsis thaliana Recognized [ATR]) gene products by matching Arabidopsis thaliana resistance (Recognition of Peronospora parasitica [RPP]) gene products triggers localized cell death (a hypersensitive response) in the host plant, and this inhibits pathogen development. The oomycete pathogen, therefore, is under
