Anatomical locations of microinjection and neuronal recording sites. A: an original slide of the pons (+9.8 mm from obex) showing an actual microinjection site (arrow) in the elPBN of a cat. B and C: composite maps displaying histologically verified sites of microinjections and neuronal recordings in the elPBN (B) and rVLM (C) in cats. Left: magnified areas indicated by boxes at right. Brain sections indicate combinations of planes of brain stem rostral to the obex (Berman's atlas for the cat). ★, Recording in the elPBN; □, ▲, and ●, microinjection of aCSF, kynurenic acid, or dl-homocysteic acid, respectively, into the elPBN and recording in the rVLM in the cat; ○, microinjection of kynurenic acid outside the elPBN and recording in the rVLM in the cat. BC, brachium conjunctivum; PBN, parabrachial nucleus; dPBN, dorsal lateral subnucleus of PBN; elPBN, external lateral PBN; mPBN, medial subnucleus of PBN; ION, inferior olivary nucleus; RFN, retrofacial nucleus.
