Distribution of FLI neurons at two anteroposterior levels of the medulla depicted in the transverse plane for a representative animal from each stimulus condition. Sections are ordered from rostral (A, level 4) to caudal (B, level 1). Numbers on theleft indicate distance from the obex. Open circles denote moderately stained nuclei that appeared brown in color, whereas filled circles denote intensely stained nuclei that appeared black or brown–black in color. Dashed lines depict borders between reticular formation subdivisions. Abbreviations for all figures: AP, area postrema;Cu, cuneate nucleus; DCN, dorsal cochlear nucleus; Ecu, external cuneate nucleus;Gi, gigantocellular reticular nucleus;Gr, gracilis nucleus; IO, inferior olive;IRt, intermediate reticular nucleus; LRN, lateral reticular nucleus; MdD, dorsal medullary reticular nucleus; MdV, ventral medullary reticular nucleus; MVe, medial vestibular nucleus;mVII, facial nucleus; mXII, hypoglossal nucleus; NA, ambiguus nucleus; NST, nucleus of the solitary tract; PCRt, parvocellular reticular nucleus; py, pyramidal tract;sV, spinal trigeminal nucleus; SVe, spinal vestibular nucleus; and VLM, ventrolateral medulla.
