Normal hippocampal synaptic plasticity in IκBαM/M KI mice. A) No change in input-output relationship. N = 15-17 slices. B) No change in paired pulse facilitation at the indicated inter-pulse intervals. N = 26-34 slices. C) Similar changes in fEPSP slope following a weak (1 × TBS) and standard (3 × TBS) LTP induction stimulus. N = 14-20 slices.
