Specifically, Figure 2 is from Figure 2b: Avila-Costa MR, Colín-Barenque L, Aley-Medina P, et al. (2005) Bilateral increase of perforated synapses after unilateral dopamine depletion, Intern. J. Neuroscience, 115: 79–86, DOI: 10.1080/00207450490512669. Figure 4a is from Figure 11–1 of Avila-Costa MR, Gutiérrez-Valdez AL, Ordonez-Librado JL, et al.
