Figure 4.
Effects of D2 and α2-adrenergic receptor antagonists on VTA-evoked CA signals observed in the mPFC . (A) Color plots illustrate the electrically-evoked voltammetric signals obtained from individual rats and recorded after initial injections of saline and 20 min after subsequent injections of raclopride (RAC, top) and idazoxan (IDA, bottom). (B) [CA]-versus-time traces averaged from 6 rats demonstrate effect of RAC and IDA in 20 and 40 min after the injections (mean±SEM). The peaks of CA signals were aligned across rats.
