Figure 4

The MBO axonal tree. Low-magnification photomicrographs of the sagittal sections of the hypothalamus showing DiI labeling of the fibers of mammillary body tracts following DiI insertion into the mammillary body on different prenatal stages: (A) E14, (B) E19, (D) E21. Mammillotegmental tract–arrow; mammillary peduncle–arrowhead; mammillothalamic tract–asterisk. (C) E16, high-magnification confocal image of the sagittal section of the mammillary body showing retrogradely labeled axons and neurons following DiI insertion in the tegmental region. Scale bars: (A,B,D) = 100 μm, (C) = 80 μm.
