Leptogenesis is a mechanism that relates the generation of baryon asymmetry with the spectrum of light neutrino masses. An upper bound on the light neutrino mass scale has been derived from the observed baryon asymmetry in the framework of the original Fukugita and Yanagida proposal, based on the decays of the lightest heavy Majorana neutrino. We review the dynamics of leptogenesis in the simplified form that has been most studied and extend the system to include the generation and evolution of partial lepton asymmetries. The relation bewtween baryon asymmetry and light neutrino masses is explored in this context.
