Retraction: The presence of perforated synapses in the striatum after dopamine depletion, is this a sign of maladaptive brain plasticity? (Microscopy (2014) 63: 6 (427–435) DOI: 10.1093/jmicro/dfu032)

Abstract

This is a retraction of: Verónica Anaya-Martínez, Ana Luisa Gutierrez-Valdez, Jose Luis Ordoñez-Librado, Enrique Montiel-Flores, Javier Sánchez-Betancourt, César Sánchez Vázquez del Mercado, Leonardo Reynoso-Erazo, Rocío Tron- Alvarez, Maria Rosa Avila-Costa, The presence of perforated synapses in the striatum after dopamine depletion, is this a sign of maladaptive brain plasticity?, Microscopy, Volume 63, Issue 6, December 2014, Pages 427–435, https://doi.org/10. 1093/jmicro/dfu032 The Editors were alerted in October 2023 about potential issues with the images presented in Figures 2, 4a and 4b, following a post on PubPeer (https://pubpeer.com/publications/ A2028D85822430C43FD65B3D1C3C28). The Editors contacted the corresponding author, who said the figures in question were altered from previous publications by the same corresponding author and reused without attribution, but that the relevant results were not altered. 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. The presence of perforated synapses in the striatum after dopamine depletion. Is this a sign of negative brain pasticity? (2008) In: Kaiser TF and Peters FJ (eds) Synaptic Plasticity: New Research: pp. 113–143, (Nova Science Publishers, Inc.). Figure 4b is from Figure 11–2 of the same work. The Editors have decided to retract the article as the image manipulation described above undermines the reliability of the study.
