We report detailed dielectric investigations of Pr 1-x Ca x MnO 3 (PCMO, x = 0.5) ceramics, a member of the perovskite manganite family that exhibits a colossal magnetoresistance. Analysis of the electrical conductivity and dielectric constant data revealed that in the low temperature phase, below 4
