We report simultaneous hydrostatic pressure studies on the critical temperature Tc and on the pseudogap temperature T∗ performed through resistivity measurements on an optimally doped high-Tc oxide Hg0.82Re0.18Ba2Ca2Cu3O8+δ. The resistivity is measured as function of the temperature for several different applied pressure below 1GPa. We find that both Tc and T∗ increases linearly with the pressure. This result demonstrate that the well known intrinsic pressure effect on Tc is also present at T∗ and both temperatures are originated by the same superconducting mechanism.
