Sumario:The OPERA experiment aims at the direct confirmation of the leading oscillation mechanism in the atmospheric sector looking for the appearance of ν<sub>τ</sub> in an almost pure ν<sub>μ</sub> beam (the CERN CNGS beam). In five years of physics run the experiment collected 17.97 × 10<sup>19</sup> p.o.t. The detection of τS produced in ν<sub>τ</sub> CC interactions and of their decays is accomplished exploiting the high spatial resolution of nuclear emulsions. Furthermore OPERA has good capabilities in detecting electron neutrino interactions, setting limits on the ν<sub>μ</sub> → ν<sub>ℯ</sub> oscillation channel. In this talk the status of the analysis will be presented together with updated results on both oscillation channels.
