In the version of this article initially published, “−2” and “−4” on the y axis of Fig. 5d should have been “−20” and “−40”. Further, the scale values near the spike waveforms in Fig. 2a, now reading “100 μs” appeared originally as “10 μs.” The errors have been corrected in the HTML and PDF versions of the article.
