A brain machine interface (BMI) provides the possibility of controlling artificial arms for patients with severe motor dysfunction by only using their thoughts. However, most of researchers have been using only unilateral hand movements for decoding motor imagery which are not enough for daily-life applications. To provide multidimensional control, we describe the first reported decoding of bilateral hand movements by using single-trial magnetoencephalography (MEG) signals as a new approach to enhance a user’s ability to interact with a complex environment. In addition, bilateral movement requires multitask processing whose neural correlates remains unclear. In order to study the multitasking neural process, we analyzed and decoded in real-time the brain activity of four types of simultaneous bilateral hand movements using non-invasive measurement.

About CiNet’s Friday Lunch Seminars:
The Friday Lunch Seminar is CiNet’s main regular meeting series, held every week at 12:15 in the beautiful main lecture theatre on the ground floor at CiNet. The talks are typically 40mins long and orientated towards an inter-disciplinary audience. They are informal, social, and most people bring their own lunch to eat during the talk. They are open to anyone who is feeling curious and wants to come, regardless of where you work.
