Dependency on K⁺ o of FC-induced modification of DH_s neurotransmission. (A) Plots showing that effect of FC on the P-PSP_DR alters systematically as [K⁺]_o is varied over the range 0~3 mM. Format same as Fig. 1B. (B) Linear regression analysis of the relationship between magnitude of FC-induced alteration of P-PSP_DR and [K⁺]_o revealing that over the range 0~3 mM a 1 mM change of [K⁺]_o is accompanied by nearly a 37% alteration of DH_s neuron responsivity. Note that at [K⁺]_o values less than 1.8 mM FC induces LTD; however, at values exceeding 1.8 mM FC induces LTP.
