A Work of Art: The Mystery of the First Heartbeat

Why It Matters

Mapping the dynamic emergence of the first heartbeat could clarify causes of congenital heart malformations and altered conduction after injury, guiding future diagnostics and therapeutic strategies. Cross-disciplinary approaches also expand tools for probing complex developmental and disease-related transitions.

Summary

Researchers at Oxford, led by developmental biologist Claudio Cortés, are combining live imaging with computational art by Andy Lomas to study how the embryo’s first heartbeat emerges from initially unsynchronised cells. Using visual models—metronomes, Mexican-wave analogies and cell-potential simulations—they show that local interactions and simple rules can produce coordinated, self-sustaining rhythmic waves without a central controller. The work highlights dynamic transitions in rhythm formation and suggests that morphology and function co-emerge during early heart development. The collaboration reframes static textbook views into a movie-like understanding of how order arises from cellular randomness.

Original Description

_“How do we get order emerging from randomness?”_

Poetically speaking, our heart is our centre – an organ that has come to represent our feelings, emotions and love for one another. Medically speaking, it is still something wondrous – a biological powerhouse that has the capacity to beat billions of times over the course of a human life. But what prompts that very first heartbeat in a developing embryo? With no evident ‘control system’, the coordination of the first heartbeat has been something of a mystery. Here, Dr Claudio Cortés (Oxford’s Department of Physiology, Anatomy and Genetics) discusses how collaborating with those from other fields – such as computational artist Andy Lomas – is helping improve our understanding of how dynamic patterns and rhythm can spontaneously emerge within previously unsynchronised cells.
