Motion control mechanisms of the brain is a major subject of neuroscience, and the accumulated knowledge is expected to feed back to society. Adaptive control movement of upper arm has been tried to be understood referring to control theory in control systems engineering. Since optimal feedback control (OFC) model was introduced into neuroscience in early 2000s, OFC may be one of the most challenged models to test its plausibility. After briefly reviewing the history of motion control models in neuroscience, in this talk, the motion control mechanism of upper arm is reconsidered in the framework of OFC referring to works carried out in my laboratory, which include simulation and behavioral studies, and unit recording studies in the monkey. OFC was able to fairly well account for information representation in the motor cortex and some aspects of the behaviors except motor learning when a cost function was appropriately defined. Finally, I would like to mention to a future applicational work.

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.
