SERGIO PASTOR CARPI Istituto de Fisica Corpuscular Valencia: After a brief review of the cosmic neutrino background, one of the predictions of the standard cosmological model, and its effects on the evolution of the Universe, I will describe the bounds that can be extracted on neutrino properties from cosmological data, in particular with recent CMB data from Planck, such as the total neutrino mass or the effective number of neutrinos.
