Figure 1. The group II agonist L-CCG-1 differently affects synaptic transmission in areas CA1 and SUB.

(A, B) Field potential recordings were performed and the group II agonist L-CCG 1 was bath-applied in various concentrations. Field potentials were depressed in a concentration-dependent manner (SUB: n = 4; CA1: n = 5). (C) DCG-IV (1 µM) suppressed fEPSP in the SUB to a similar extent as observed with 10 µM L-CCG-1 (SUB: n = 5; all in presence of the NMDA receptor antagonist APV, 50 µM).
