FKBP1b overexpression reversed the age-related augmentation of the sAHP in hippocampal neurons from the MWM-tested aged animals. A, Representative traces of the sAHP following a burst of four action potentials elicited by an intracellular current pulse (lower trace) in hippocampal neurons of an Aged-Control rat (blue) and an Aged-FKBP1b rat (red). B, sAHP amplitude and duration were substantially greater in neurons from Aged-Control rats than neurons from Young-Control rats (p < 0.0001) or Aged-FKBP1b (p < 0.0001) rats, but did not differ between Aged-FKBP1b and Young-Control rats. Asterisks denote a significant difference from Aged-Control.
