Pancreatic β-cells are highly connected, and this network is crucial for the pulsatile release of insulin. Here Salem and colleagues demonstrated the existence of leader β-cells that respond first to glucose and are more closely linked to the other β-cells. They also showed that glucose increases β-cell calcium dynamics and connectivity between the leader and non-leader β-cells.
