Early Repetitive Transcranial Magnetic Stimulation Exerts Neuroprotective Effects and Improves Motor Functions in Hemiparkinsonian Rats

Figure 5

Representative TH-positive neurons in the substantia nigra pars compacta (a, b) and TH-positive fibers in the striatum (c, d) from sham control and rTMS-treated animals sacrificed at 1 week and 4 weeks post-6-OHDA lesion. Note the obvious reduction in TH-positive neurons or fibers in the lesioned hemisphere (left side) of the rTMS group at 1 week and 4 weeks post-6-OHDA lesion when the percentages of TH-positive neuron loss in the substantia nigra (e) and TH-positive fiber loss in the striatum (d) were compared to those in the sham treatment group. (unpaired -test).
