title: The soothing touch: microglial contact influences neuronal excitability.
abstract: Resting microglial cells in the brain scan their environment with their processes, primed to react to injury and disease. In this issue of Developmental Cell, Li and colleagues (2012) report that resting microglia also react to physiological neuronal activity, sending their processes toward highly active neurons to regulate their excitability.
