Share:

Description

Activity profiles of spinal motoneurons recorded during fictive motion (scratching) evoked in an immobilized decorticate cat.

Usage

1
data("emg96627009")

Format

A data frame with 31979 observations on the following 4 variables.

ENG-PB

a numeric vector of EMG data of the posterior bicep

ENG-GM

a numeric vector of EMG data of the medial gastrocnemius

ENG-FDL
