Two specific algorithms were implemented: a standard Kalman filter and an unscented Kalman filter. A recursive Bayesian estimation framework was proposed for decoding EMG signals together with kinematics from M1 spike trains. Based on the guidance of these results, we identified the locations optimal for chronic electrode implantation and subsequently carried on chronic neural data recordings.

With ample data collected from neurons from a large brain area, we performed a spike triggered average (SpTA) analysis and got a series of density contours which revealed the spatial distributions of different muscle-innervating neurons corresponding to each given muscle. Subdermal intramuscular EMG electrodes were implanted to 8 right leg/thigh muscles.

The current study, as a follow-up extension, investigates whether lower limb kinematics and muscle activity characterized by electromyography (EMG) signals during monkey performing stand/squat movements can be accurately decoded from neural spike trains in primary motor cortex (M1). We previously reported a system for training monkeys to perform visually guided stand and squat tasks. However, similar topics regarding lower limb remain relatively scarce. 6Advanced Innovation Center for Intelligent Robots and Systems, Beijing Institute of Technology, Beijing, ChinaД®xtensive literatures have shown approaches for decoding upper limb kinematics or muscle activity using multichannel cortical spike recordings toward brain machine interface (BMI) applications.5Collaborative Innovation Center for Brain Science, Huazhong University of Science and Technology, Wuhan, China.4Department of Rehabilitation Medicine, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.3Center for Neural Interface Design, School of Biological and Health Systems Engineering, Arizona State University, Tempe, AZ, USA.2Center for Neuropsychiatric Disorders, Institute of Life Science, Nanchang University, Nanchang, China.1Neural Interface and Rehabilitation Technology Research Center, School of Automation, Huazhong University of Science and Technology, Wuhan, China.
