The early evolution of a protoneutron star depends both on the equation of state and neutrino interactions at high density. We identify the important sources of neutrino opacity and through model calculations show that in-medium effects play an important role in determining the neutrino mean free paths. The effects due to Pauli-blocking and many-body correlations due to strong interactions reduce the neutrino cross sections by large factors compared to the case in which these effects are ignored. We discuss these results in the context of neutrino transport in a protoneutron star.
