1. Inferência do tempo de atividade neural a partir do efeito BOLD em ressonância magnética funcional / Inference of neural activity time from BOLD effect in functional magnetic resonance imaging
A inferência do curso temporal da atividade neural a partir do efeito BOLD é um importante problema, ainda em aberto. A forma da curva BOLD não reflete diretamente as características temporais da atividade eletrofisiológica dos neurônios. Nessa tese, é introduzido o conceito de tempo de processamento neural (TPN) como um dos parâmetros do modelo biof

2. ConstruÃÃo de um nariz artificial usando redes neurais
The animals interact with environment in several ways. The smell around them has an extremely importance in the information transport, essential for survival. Such as for the animals, the smell plays an important rule for human beings. Due to this importance, the study in the human olfactory system is very helpful and started very long time ago. Although it

3. Toward an evolutionary perspective on conceptual representation: Species-specific calls activate visual and affective processing systems in the macaque
Non-human primates produce a diverse repertoire of species-specific calls and have rich conceptual systems. Some of their calls are designed to convey information about concepts such as predators, food, and social relationships, as well as the affective state of the caller. Little is known about the neural architecture of these calls, and much of what we do

4. Modeling facilitation and inhibition of competing motor programs in basal ganglia subthalamic nucleus–pallidal circuits
The motor symptoms of Parkinson's disease (PD) implicate the basal ganglia (BG) in some aspect of motor control, although the role the BG play in regulation of motor behavior is not completely understood. The modeling study presented here takes advantage of available cellular, systems, and clinical data on BG and PD to begin to build a biophysically based ne
