EEG connectivity measures could provide a new type of feature space for inferring a subject's intention in Brain-Computer Interfaces (BCIs). However, very little is known on EEG connectivity patterns for BCIs. In this study, EEG connectivity during motor imagery (MI) of the left and right is investigated in a broad frequency range across the whole scalp by combining Beamforming with Transfer Entropy and taking into account possible volume conduction effects. Observed connectivity patterns indicate that modulation intentionally induced by MI is strongest in the gamma-band, i.e., above 35 Hz. Furthermore, modulation between MI and rest is found to be more pronounced than between MI of different hands.

Anyone can teach themselves to have a memory the size of a champion, a study shows. Scans found ordinary members of the public had brains as sharp as the world's greatest memorisers after a simple brain training course using'memory palaces'. It means the ability to perform astonishing feats - such as remembering lists of several dozen words - can be learned, say scientists. After 40 days of daily 30-minute training sessions individuals who had typical memory skills at the start and no previous practise more than doubled their capacity. In this study, the learning strategy scientists chose was loci training, also known as creating a'memory palace'.
