From the project
Brain(Cerebro) es una placa de desarrollo, que cuenta con un EEG (electroencefalograma) que mediante electrodos medimos la actividad cerebral de 12 Hz - 30 Hz, que corresponde a la concentración, con el objetivo de utilizarlo como una herramienta de aprendizaje en distintas disciplinas que se puede llevar a cualquier parte para aprender mientras te diviertes. De igual manera se está desarrollando una plataforma para facilitar el uso y el aprendizaje con Brain.
