Finger movement inference using M1 neural activities

The paper presents the neural decoding result of finger or wrist movements using the primary motor cortex （M1） neural activities prior to its movement. It is well known that the observations of motor commands in brain are in advance before motor movements in the central nerve system. Readiness potential （RP） for electroencephalogram （EEG） has become an important domain of research. Likewise, pre-movement neural responses in M1 primary motor cortex have been ob- served. The neural activity data before 1 s. were used for neural decoding when the actual movements happened around 1 s. The obtained decoding accuracy in novel method reaches as high as 95 % with 30 randomly selected neurons.
