Location of the presumed pre-Bötzinger complex (preBötzC) in goats. A: medullary parasagittal section of an unoperated control goat that was Nissl stained to illustrate the ventrolateral respiratory column, including nucleus ambiguus (NA) and the facial nucleus (FN) (×1). Inset B extends from ∼2.0 to 4.6 mm rostral to obex, and we presume the portion 2.5–3.5 mm rostral to obex and ventral to NA is the preBötzC. C: parasagittal section (×4) from the same goat 4.7 mm lateral to the midline and 2.0–4.6 mm rostral to obex (comparable to inset B); it is immunostained for neurokinin-1 (NK1) receptor (NK1R) expressing neurons. The dashed box extends from 2.5 to 3.5 mm rostral to obex, and we presume it is the preBötzC area. Inset D (×40) is a neuron from within the dashed box in C. D, dorsal; V, ventral; R, rostral; C, caudal.
