Erratum to: Exp Brain Res (2012) 220:135–145 DOI 10.1007/s00221-012-3124-6

The original version of this print publication unfortunately contains an error in the alpha value under “Data analysis” section (i.e., p. 139, right-hand side, 1st paragraph, 3rd line). It is now corrected as given in the sentence below:

“Then, instead of using the likelihood test, we tested the adequacy of our data compared to the theoretical distribution with a χ 2-goodness-of-fit test (α = 0.05).”
