In the version of this article initially published, two citations were inadvertently omitted. To correct this, the following two sentences were added to the second paragraph of the introduction, following the sixth sentence. “One line of work has supported the theory by demonstrating that arm movement errors evoke complex spikes51,52 and that subsequent learned changes in motor behavior are associated with suitable changes in simple spike responses51. This work demonstrates a strong correlation, but stops short of showing cause-and-effect links between individual complex spikes, changes in simple spikes and behavioral learning.” Two references were also added to the reference list as follows:

In addition, the second sentence of the abstract should read “Many elements of this hypothesis have been supported by prior experiments, and correlations have been found between complex spikes, simple-spike plasticity and behavior during the learning process.” The errors have been corrected in the HTML and PDF versions of the article.
