1. ENHANCE KNOWLEDGE COMMUNICATION AND LEARNING: A SURPRISE PARADOX
Abstract Human-computer interface is a pivotal factor that can promote or deter the effectiveness of Web-based knowledge communication. There is abundant research that strain to improve interfaces by considering user needs through usability studies; however, few researches consider the incorporation of automatic brain mechanisms in order to improve knowledge

2. A comparative study: use of a Brain-computer Interface (BCI) device by people with cerebral palsy in interaction with computers
RESUMO Este artigo apresenta um estudo comparativo entre pessoas com paralisia cerebral e pessoas comuns, de diferentes idades, utilizando um equipamento de Brain-computer Interface (BCI). A pesquisa é de abordagem qualitativa. Trabalhou-se com Estudo de Casos Obser vacionais. Foram avaliadas pessoas com paralisia cerebral e pessoas comuns em Portugal e no

3. Statistical evaluation of a novel SSVEP-BCI stimulation setup based on depth-of-field
Abstract Introduction The main drawback of a Brain-computer Interface based on Steady-State Visual Evoked Potential (SSVEP-BCI) that detects the emergence of visual evoked potentials (VEP) in reaction to flickering stimuli is its muscular dependence due to users must redirect their gaze to put the target stimulus in their field of view. In this work, a nove

4. Brain-computer interface: proposal of a shaping-based training
INTRODUCTION: Persons affected by certain motor disabilities such as amyotrophic lateral sclerosis can evolve with important motor and speech difficulties in communication. A BCI (Brain Computer Interface) is a system that allows interaction between the human brain and a computer, permitting the user to control a communication channel through his or her brai

5. Detecção de potenciais evocados P300 para ativação de uma interface cérebro-máquina. / Brain-computer interface based on P300 event-related potential detection.
Interfaces cérebro-computador ou Interfaces cérebro-máquina (BCIs/BMIs do inglês Brain-computer interface/Brain-machine interface) são dispositivos que permitem ao usuário interagir com o ambiente ao seu redor sem que seja necessário ativar seus músculos esqueléticos. Estes dispositivos são de extrema valia para indivíduos portadores de deficiênc

6. Control system image for individuals or quadriplegic with brain damage / Sistema de controle por imagem para indivíduos tetraplégicos ou com lesões cerebrais
Um dos grandes desafios para a reabilitação de indivíduos que sofreram traumas resultando na sua incapacidade de interação com o ambiente é o desenvolvimento de um sistema que possibilite a esse indivíduo a mínima capacidade de comunicação. Em casos extremos, indivíduos perdem os movimentos dos membros superiores, pescoço e a capacidade de comuni

7. Control of a two-dimensional movement signal by a noninvasive brain-computer interface in humans
Brain-computer interfaces (BCIs) can provide communication and control to people who are totally paralyzed. BCIs can use noninvasive or invasive methods for recording the brain signals that convey the user's commands. Whereas noninvasive BCIs are already in use for simple applications, it has been widely assumed that only invasive BCIs, which use electrodes

8. Crystal Structure of a Homolog of Mammalian Serine Racemase from Schizosaccharomyces pombe*
d-Serine is an endogenous coagonist for the N-methyl-d-aspartate receptor and is involved in excitatory neurotransmission in the brain. Mammalian pyridoxal 5′-phosphate-dependent serine racemase, which is localized in the mammalian brain, catalyzes the racemization of l-serine to yield d-serine and vice versa. The enzyme also catalyzes the dehydration of d
