Figure 1: Photomicrograph of a 6-OHDA lesioned rat striatum immunostained for tyrosine hydroxylase (TH). Densities of TH-immunoreactivity striatal fibers are clearly reduced after the 6-OHDA injection (right side) as compared to the densities of striatal TH-immunoreactivity fibers in control rat (left side).
