Restoration of CA1 long-term potentiation (LTP) in tenascin-C (TNC−/−) mice by the L-type voltage-gated Ca2+ channel (L-VGCC) activator Bay K-8644. (A) Four trains of theta-burst stimulation (TBS) of Schaffer collateral/commissural fibers induced impaired LTP in the CA1 region of TNC−/− mice. (B) LTP in TNC−/− mice can be restored to wild-type levels by the L-VGCC activator Bay K-8644 (10 μM). Mean and SEM values are shown, the mean slope of field excitatory postsynaptic potentials (fEPSPs) recorded 10 min before the induction of LTP was set to 100%.
