Resumen:
We review recent tentatives to find non-Gaussian structure in thecosmic microwave background. We show general expressions for thefull angular bispectrum ${\cal C}_{\ell_1 \ell_2 \ell_3}$ in terms ofinflationary slow roll parameters. We stress that a real detection ofnon-Gaussianity in the COBE-DMR dataset would imply that an important component of the anisotropies arises from processes other than primordial quantum fluctuations.
