We present reliable many-body calculations for the t\mathrm\text\ensuremath-t^\ensuremath'\mathrm\text\ensuremath-t^\ensuremath'\ensuremath'\mathrm\text\ensuremath-U Hubbard model that explain in detail the results of recent angle-resolved photoemission experiments on electron-doped high-temperature superconductors. The origin of the pseudogap is traced to two-dimensional antiferromagnetic spin fluctuations whose calculated temperature-dependent correlation length also agrees with recent neutron scattering measurements. We make specific predictions for photoemission, for neutron scattering, and for the phase diagram.
