A Study Exploring Neuronal Activities in Spatial Reaching and Grasping Towards Brain-Machine Interface

摘要：

　　Restoring reaching and grasping functions of upper limbs is a focus in Brain-Machine Interface(BMI)researches.Understanding how local M1 neurons innervate flexible coordinated upper limb reaching and grasping is important for the design of BMI systems that attempt to reproduce the same actions from decoding neuronal activities.In this paper,we presented a study combining to explore the neuronal activities in spatial reaching and grasping.A non-human primate as our subject was trained to perform a series of well-designed spatial reaching and grasping behaviour tasks on a special apparatus.Neuronal activities in primary motor cortex(M1)were acquired with 3 Floating Microelectrode Arrays(FMA).The behaviour experimental paradigm we employed in this study enabled us to investigate how important parameters in reaching and grasping tasks,including the position,orientation,shape of target objects,were represented in neuronal activities.Through the results,a preliminary categorizing of isolated neuron units was given.Neuron selection can be performed based on the neuronal categorizing information for proposed classifiers.These results enabled us to develop neural decoding methods aiming to discriminate various reaching and grasping patterns or identify the transition of different movement stages in BMI.
