After publication of our article [1], we became aware that
there were two minor data loading and analysis scripting
errors in the human EEG data processing pipeline. These
errors affected the channel loading/grouping and sleep/
wake coding of EEG data. We have re-analysed all the
data affected by these errors. The errors do not affect any
interpretations or conclusions, thus no changes to the text
are required apart from correcting p values and raw values
affected by the errors. There are no changes to statistical
significance or lack-thereof. The errors affect data presented
in Fig. 3, Fig. 4, Fig. 5, and Additional file 3: Figure
S3 and thus we have re-plotted these figures (see below)
