Pacemaker neurons are present in the preBötC circuitry of mouse embryos and their role in driving respiratory network activity changes during the critical period immediately before birth.

Cell-penetrating peptide drugs prevent adrenergic regulation of pacemaker channels without altering the overall response of the cell to cAMP.

A genome wide transcriptome dataset of the embryonic zebrafish heart with high spatial resolution was established and used to identify a novel mechanism regulating pacemaker function.

A transport protein enables leaf beetle larvae to take up and store plant toxins and use them as part of their own defense strategy.

Using a short peptide to regulate the activity of HCN ion channels illustrates how physiological modulators could inspire new drugs. .

RNA sequencing reveals the finer details of circadian variation in the mammalian master pacemaker over 24 hours, which suggests that transcriptional timing influences clock resetting mechanisms.

Why is the alligator heart so similar to the hearts of birds and mammals?
