title: Spontaneous respiratory activity of phrenic and intercostal Renshaw cells.
abstract: Activity of Renshaw cells evoked by electrical stimulation of either phrenic or internal intercostal axons was extracellularly recorded in anaesthetized spontaneously breathing cats. The response of all the studied units to antidromic invasion of the corresponding motoneurones was related to the respiratory cycle and some units displayed spontaneous respiratory activity. Recurrent IPSPs were recorded on phrenic and intercostal motoneurones.
