(A) Individual EPSPs and paired pulse facilitation of DML afferents is not altered by application of KN62; in this case there was a slight (not significant) increase in PPF after application of the drug. (B and C) PTP in DML. (Upper) Superimposed pre- and posttetanus (5 s) EPSPs under control (B) or KN62 (C) conditions. (Bottom) Subtraction of pre- from posttetanus EPSP reveals that PTP in DML is unaffected by KN62. (D) The time course of PTP in DML is not altered by extracellular application of KN62. Time scale as in Fig. 2 D and G.
