The kinematics of hand movement have been reported to be encoded in neural activities recorded at the primary motor cortex accompanying or immediately preceding the movement. In our earlier study, we demonstrated that the speed of imagined hand movements can be represented in the noninvasive EEG recordings and continuously decoded. In the present work, we aimed to systematically examine the spectral-temporal dynamics of imagination-related speed embedded in multiple frequency bands of EEG activity, including the alpha, beta and gamma bands and search for the optimal speed decoding for movement imagination.
据报道，手部运动的运动学信息编码在运动伴随或即将开始时在初级运动皮层记录的神经活动中。在我们早期的研究中，我们证明了想象手部运动的速度可以在无创脑电图记录中得到体现并持续解码。在当前的工作中，我们旨在系统地研究嵌入脑电图活动多个频段（包括α、β和γ频段）中的与想象相关速度的频谱-时间动态，并寻找运动想象的最佳速度解码方法。
