Summary WG2 Part 1a: using neutrinos to study partons in the nucleon and the nucleus at the neutrino factory

A neutrino deep-inelastic scattering experiment at a neutrino factory is described. The improvements possible in extracting parton distribution functions both within the nucleon and the nuclear environment are shown. The intriguing possibility of using (anti)neutrino scattering off a polarized target to determine the individual partonic spin contributions to the nucleon is discussed.
