A Brain tissue of mice treated with (l-dopa + PQ) showing restoration of cellularity with numerous neuronal pyramidal cells showing brownish pigment within cytoplasm (black arrows). B Brain tissue of mice treated with (l-dopa + PQ) showing restored cellular Purkinje cell layer (white arrow) with numerous pigmented neuronal cells (black arrows) (H&E X 400). C Brain tissue of mice treated with (R + PQ) showing cellular, restored Purkinje cell layer with several prominent pigmented neuronal cells (black arrows). D Brain tissue of mice treated with (R + PQ) showing dense cellularity, scattered cells appeared with irregular contours and deeply basophilic, hyperchromatic nuclei (white arrows). Still, some pyknotic nuclei were seen (thin black arrows) (H&E X400)
