On the cover…

1 Oct 2020

Congratulations to Dr Karen O’Connor on the publication of her topical review in The Journal of Physiology, which was accompanied by artwork published on the journal cover this month.

Karen’s studies performed in the course of her doctoral training, under the supervision of Prof. John Cryan and Prof. Ken O’Halloran, focussed on the role of gut-brain-axis signalling in cardiorespiratory function, leading to a hat-trick of papers in the Lancet publication EBioMedicine. The topical review summarises the growing literature in this emerging field of study.

Many thanks to Dr Ken O’Riordan for the creative artwork featured on the cover.
