Chronic recording of EMG activity from large numbers of forelimb muscles in awake macaque monkeys

J Neurosci Methods. 2000 Mar 15;96(2):153-60. doi: 10.1016/s0165-0270(00)00155-2.


Studies of the neural control of movement often require or benefit from long-term recording of EMG activity from large numbers of muscles involved in a particular motor task. While chronic recording of EMG activity has been described in a number of previous monkey studies, the number of muscles recorded has been somewhat limited and the implantation approach has been highly invasive procedures. This paper presents two EMG implant fabrication and surgical implantation methods that are suitable for use in monkeys, relatively non-traumatic and capable of simultaneous recording from 24 or more muscles.
