TO THE READERSHIP: An error appeared in the article by Gogos et al. (Gogos AJ, Young JS, Morshed RA, et al.

Published online June 5, 2020. doi:10.3171/2020.3.JNS193434).
In Fig. 1, panel A1, the twist electrode is mistakenly depicted entering the skull. This has been corrected in the figure shown below.
