Raw data example of DCN spike activity correlated with licking, whisking and respiratory behavior. (A) Raw data examples of single-unit DCN spike activity with licking, whisking and respiratory behavior. Under each trace are time markers marking the tongue-to-spout contact times for the licking trace, the time of whisker beam crossing for whisking trace, the end-of-expiration and inspiration times for the respiratory trace, and spike activity for the DCN spike train recording, respectively. (B) Histograms showing the inter-lick interval, inter-whisking interval, inter-expiration interval, and inter-spike interval distribution. (C) Histograms showing the cross-correlation between DCN spikes with licking, whisking, and expiration events.
