Figure 4.
Effects of ERK1/2 inhibitors on the firing rate of LC neurons. (A) Representative episodes of firing rate recording from LC neurons before (baseline) (left panel) and after 30 mins of drug applications (right panel). The top, middle and bottom traces show the application of U0126, FR180204 and the vehicle (DMSO), respectively. (B-D) Summarized results show the change in the SFR upon U0126 (B), FR180204 (C) and DMSO (D) application. The asterisks indicate a significant difference compared to the control at p < 0.05 (*) or at p < 0.01 (**).
