From: An output-null signature of inertial load in motor cortex
a EMG experiment to measure the adaptation of muscle activity to a change in inertial load. b Optogenetic inactivation experiment to test the necessity of motor cortex for load-related changes in muscle activity. c Neural recording experiment to measure the effects of load changes on cortical dynamics. d Optogenetic perturbation experiment to measure the effect of cerebellar output on cortical activity. e Motor unit recording experiment to measure the effect of load changes on spinal motoneuron activity.
