Brain computer interface in short training tasks

Since the first recorded research of electrical activity in the brain of animals (Richard Caton, 1875) and later of the human brain (Hans Berger, 1924) this issue has been a productive area of research in different fields: neuroscience, engineering, education and many others. With the advancements of sensor materials and construction, upgraded computer processing power and with the development of advanced signal processing algorithms new possibilities of use have opened up. Recent studies in the field of brain-machine interface (BMI) or brain-computer interface (BCI) provided usable non-invasive BCI systems characterized by portable which can be used exteriorly to rigorous laboratory requirements. The usage of the electroencephalogram (EEG) in two versions: one with a semi-dry polymer sensor (5 + 2 reference sensor) and the other sensors wetted by saline (14 + 2 reference sensors) have been tested. A brief background of basic neuroscience is given as well as signal processing, used software and hardware. The observed deficiencies and potential use in learning and training are presented by testing successfulness of short training tasks completion with trained and untrained subjects.
