Rostrocaudal distribution of retrogradely FG-labeled cells in the hypothalamus following FG injections in Sp5C.

<p>A–E: Bar histograms of the number of FG neurons (mean ± SEM; n = 21) at the ipsilateral (filled bars) and contralateral (empty bars) side on coronal sections plotted as a function of the posterior distance (mm posterior to bregma) within the five hypothalamic nuclei: RCA: retrochiasmatic area (A), PVN: paraventricular nucleus (B), LH: lateral hypothalamus area (C), PFX: perifornical area (D) and A11 (E). Abscissa in black are for the maximum rostrocaudal extent (mm posterior to bregma) of each hypothalamic nucleus: RCA (-1.6 to -1.8 mm), PVN (-0.9 to -2.1 mm), LH (-1.6 to 4.8 mm), PFX (-2.8 to -3.6 mm) and A11 (-3.3 to -4.8 mm). A-E right: Pie charts of the bilateral distribution of FG neurons in each hypothalamic nuclei.
