RESUMO

1. Nerve and muscle properties were studied in single motor units of triceps surae muscles in the cat using chronic recording techniques and intramuscular microstimulation. Recordings were made before and at intervals up to 18 months after a nerve was sectioned and sutured either to its distal stump (nerve—nerve suture) or to a muscle directly (nerve—muscle suture). Thus, each nerve and muscle served as its own control for recovery after reinnervation.
