The networks of globally coupled maps with a pacemaker have been introduced. We consider a generalization of the Kaneko model with a pacemaker represented by a single period-doubling element coupled unidirectionally with a set of other mutually coupled cells. We also investigate the dynamics of a system of two unidirectionally coupled elements, which manifests a special type of critical behaviour, known asbicriticality, at the point of simultaneous transition to chaos in both subsystems. With

We investigate the dynamics of a network with a pacemaker with two types of global coupling and the properties of universality and scaling in this system.
