Corrections: In the article “Involvement of the Basal Ganglia and Cerebellar Motor Pathways in the Preparation of Self-Initiated and Externally Triggered Movements in Humans” by Jamie Purzner, Guillermo O. Paradiso, Danny Cunic, Jean A. Saint-Cyr, Tasnuva Hoque, Andres M. Lozano, Anthony E. Lang, Elena Moro, Mojgan Hodaie, Filomena Mazzella, and Robert Chen, which appeared on pages 6029–6036 of the May 30, 2007 issue, although the authors described the results as confirming their results from previous studies in a different cohort of patients, one of the patients described in the article (patient 11) was also included in the earlier cohort [patient 5 in Paradiso G, Cunic D, Saint-Cyr JA, Hoque T, Lozano AM, Lang AE, Chen R (2004) Involvement of human thalamus in the preparation of self-paced movement. Brain 127:2717-2731].
