Central projections of vestibular afferents innervating the macula of the saccule in gerbil.
The central distribution of vestibular afferents that innervate the saccule has been investigated in the gerbil using transganglionic transport techniques. Following horseradish peroxidase injection into the saccular neuroepithelium, labeled ganglion cells were clustered at the junction of the superior and inferior ganglion. Labeled fibers entered the vestibular nuclear complex and divided into rostral and caudal branches. Terminal fields were observed in the interstitial nucleus of the vestibular nerve among the entering fibers and in the lateral vestibular nucleus. Rostrally, fibers terminated in cell group y and the nodulus; caudally, fibers ended in the descending and medial vestibular nuclei.
