Dynamical complexity and temporal plasticity in pancreatic gβb-cells

We discuss some of the biological and mathematical issues involved in understanding and modelling the bursting electrical activity in pancreatic gβb-cells. These issues include single-cell versus islet behaviour, parameter heterogeneity, channel noise, the effects of hormones, neurotransmitters, and ions, and multiple slow biophysical processes. Some of the key experimental and modelling studies are described, and some of the major open questions are discussed.
