Whole-brain activity can be simulated as a collection of BOLD signals by solving mathematical models representing neuronal circuitry organization of different brain regions. The cerebellum strongly contributes to the whole-brain dynamics. We present the formalism for a mean-field model reproducing cerebellar physiological properties, which model-core is the transfer function transforming neurons spiking-patterns into time-continuous global activity. Combined with other models integrated in simulators, like DCM (Dynamic Causal Modeling) and TVB (The Virtual Brain), our cerebellar network will allow to investigate neuronal functions at the origin of macroscopic hemodynamic properties captured by BOLD.
