Abstract

<p><b>A</b>–<b>D</b>, Tracing of anterogradely-labeled FL axons in four mice. Despite the difference of density of GFP expression among four cases shown in the photographs in the top row, labeled FL P-cell axons were distributed throughout MVN and PrH in all of the four cases. Distributions of the labeled axons in MVN and PrH for each injection are summarized in 4 images that are shown from the rostral to caudal MVN/PrH. <b>A</b>, case (#) 12L; <b>B</b>, #14L; <b>C</b>, #74R; <b>D</b>, #94R. Labeled FL P-cell axons and their boutons are respectively shown by black lines and red circles. <b>E</b>–<b>G</b>, Summary of distribution of FL P-cell axonal boutons at rostral (<b>E)</b>, middle (<b>F)</b>, and caudal (<b>G</b>) MVN. The averaged density of labeled axonal boutons was calculated from cases 12L, 14L, 74R, and 94R. Although the FL P-cell axonal boutons were observed throughout MVN, they were densely present in the medial part of parvocellular MVN/PrH. MVMC, magnocellular MVN; MVPC, parvocellular MVN; PrH, prepositus hypoglossi nucleus; 4V, fourth ventricle. Scale bars, 200 μm (<b>A</b>–<b>D</b>) and 100 μm (<b>E</b>–<b>G</b>).</p
