PMID-2340869[0] Dynamic organization of primary motor cortex output to target muscles in adult rats. II. Rapid reorganization following motor nerve lesions.
- Map out the motor cortex into vibrissa and forelimb areas using ICMS.
- Implant a simulating electrode in the vibrissa motor cortex.
- Implant EMG electrodes in the forearm.
- Sever the buccal and mandibular branches of the facial nerve.
- stimulate, and wait for forearm EMG to be elicited by ICMS. Usually occurs! Why? Large horizontal axons in motor cortex? Uncovering of silent synapses, and homeostatic modulation of firing rates?
