This third component may be correlated to atmospheric neutrino oscillations, as shown in a specific predictive seesaw model of the $3 \times 3$ neutrino mass matrix. Possible variations to include the recent LSND results are briefly discussed.6 pages, 1 figure not included, talk given at Valencia 95High Energy Physics - Phenomenologytext
