In this work we study the formation of N∗'s as a consequence of the dynamics involved in the NDDˉ∗−NDˉD∗ system when the DDˉ∗−DˉD∗ subsystem generates X(3872) in isospin 0 and Zc(3900) in isospin 1. States with isospin I=1/2 and mass in the energy region 4400−4600 MeV are found to arise with spin-parity JP=1/2+ and 3/2+, leading to predictions in this way of the existence of N∗ resonances with hidden charm and a three-body nature. We also discuss the possibility of the existence of Δc states, i.e., Δ's with hidden charm.
