Ricerca BCI

Una interfaccia cervello-computer, spesso nota attraverso il termine inglese Brain-computer interface ( BCI), rappresenta un mezzo di comunicazione diretto tra un cervello (o più in generale parti funzionali del sistema nervoso centrale), e un dispositivo esterno quale ad esempio un computer.

1	BCI2000 BCI2000 is a general-purpose system for brain-computer interface (BCI) research. It can also be used for data acquisition, stimulus presentation, and brain monitoring applications.	4225
2	EEG-based “Serious” Games Design for Medical Applications Abstract—Recently, EEG-based technology has become more popular in “serious” games designs and developments since new wireless headsets that meet consumer demand for wearability, price, portability and ease-of-use are coming to the market. Originally, EEG-based technologies were used in neurofeedback games and brain-computer interfaces. Now, such technologies could be used in entertainment, e-learning and new medical applications. In this paper, we review on neurofeedback game designs and algorithms, and propose design, algorithm, and implementation of new EEG-based 2D and 3D concentration games. Possible future medical applications of the games are discussed.	5730
3	Voluntary, spontaneous and reﬂex blinking Eye blinking consists of sequential closing and opening eyelid movements mediated by orbicularis oculi and levator palpebrae superioris muscle activation. Blinking can be performed voluntarily, spontaneously and reﬂexly (VanderWerf et al., 2003). The neural control of the antagonistic interaction between orbicularis oculi and levator palpebrae superioris muscles for the closing and opening phases and the pause between them, during each type of blinking, is distributed on partially overlapping circuitries in cortical, subcortical and brainstem structures (Schmidtke and Buttner-Ennever, 1992; Bour et al., 2000).	6113
4	Detection of eye blinks from EEG signals It was found that EEG signal obtained from voluntary eye blink condition produces clearer signals with larger amplitude than that obtained from eye movements.	4465
