Figure 5

With advancing age, the number of THir SNC neurons that stain lightly and exhibit lower cross-sectional area increase in the intact hemisphere. While THir intensity and soma area are preserved through middle-age, old subjects exhibited increased variability in these measures. SNC neurons surviving the MPTP insult in the ipsilateral hemisphere exhibited variable further declines in THir intensity and soma area. * in Figure 4 depict locations of higher magnification views presented here. Calibration bar = 50μm.
