Abstrct One of the open challenges to be solved in high Tc superconductors physics is the problem of the pseudogap phase [1], which is found in the temperature T* above Tc. The pseudogap phase is characterized by the drop of resistivity with the temperature slightly below the linearity. In this work we believe that this unusual fall is due the formation of small supercondsting fluctuations, referred as "bubbles", that convulate at the pseudogap temperature and form a narrow path for a
