Excitatory Effects of Electrical and Chemical Stimulation of the Botzinger Complex on Expiratory Activity in the Cat
Lipski and Merrill (1980) have described a population of expiration-related (ER) neurons — the so-called Bötzinger complex (Böt. c.) — in the region of the retrofacial nucleus, at the rostral pole of the ventral respiratory group (VRG). The presence of bilateral axonal projections of these neurons to the almost purely ER region of the nucleus retroambigualis (nRA) in the caudal VRG suggests that Böt. c. neurons have a role in shaping the firing patterns of nRA neurons (Fedorko and Merrill, 1984).
