Temporal Categorization of Upper Limb Muscle’s EMG Activity During Reaching and Grasping

Abstract

We describe the data processing employed to match EMG signals with the categorized behavioral movements obtained from video recordings in awake rats while reaching and grasping pellets. We want to determine whether or not, the forelimb muscles follow a temporal synchronized pattern of activity during reaching and grasping. Data processing included raw data filtering and obtaining the first derivate. We found consistency in this procedure between attempts, indicating the utility for studying the brain to spinal cord function underlying volitional and skilled movements in the rat.
