The role of neutrino heating and convection in the explosions of Type-II supernovae is reviewed. The neutrino-driven mechanism of supernova explosions is based upon the fact that high-energetic neutrinos streaming up from the hotter interior must transfer energy to the cooler layers adjacent to the nascent neutron star. While this energy deposition is unavoidable, there is still controversy about the point whether it is able to drive and power a Type-II supernova event or not. To investigate this question one-dimensional hydrodynamical simulations have been performed for the long-time evolution of the collapsed stellar core after the bounce at nuclear matter density and after the associated formation of the supernova shock. In these studies the parameters describing the neutrino emission have been varied and the influence of the temporal contraction of the central part of the nascent neutron star has been tested.
