Copper Inhibits NMDA Receptor-Independent LTP and Modulates the Paired-Pulse Ratio after LTP in Mouse Hippocampal Slices
Figure 6
Zinc blocked LTP but did not change the PPR after LTP in the CA1 region. (a) LTP was present in control slices (filled circles) but was blocked by 5 μM ZnCl2 (open circles). (b) The magnitude of the LTPs averaged one hour after the tetanus was reduced from % to % in zinc-treated slices (, ). (c) The PPR after the expression of LTP was not affected by zinc (open circles). All slices were tetanized at m in this experiment.
