  The pseudogap (PG) excitations in the framework of multiband
superconductivity are analysed.
  Calculations for the doping phase diagram of electron-doped cuprate
superconductors have been made.
  A nonrigid multiband model has been used. The interband pairing acts between
the upper Hubbard band (UHB) and midgap states created (and shifted upwards) by
doping. The appearance of two PG and two phase diagram critical points (CP) is
suggested. The larger antinodal PG reflects the destruction of the long-range
antiferromagnetic (AF) order. The second, smaller PG is a near-nodal event with
exposed doping dependence behind the first CP. It reaches the T$_c$ - dome.
Model calculations have been made. The peculiarities of the phase diagram are
determined by the doping-stimulated band overlap dynamics. The observation of
,,foreign`` carriers as compared to the ones introduced by doping is expected
to start with the vanishing PG.
