Figure 3From: Increased glutamate synaptic transmission in the nucleus raphe magnus neurons from morphine-tolerant ratsForskolin enhancement of miniature EPSC (mEPSC) frequency is greater in secondary cells from morphine-tolerant rats. A,B,C, Representative current traces with miniature synaptic events (A) and plots of cumulative distribution of mEPSC frequency (B) and amplitude (C) before and during application of forskolin (10 μM) in the same saline control cell. D,E,F, Current traces (D) and plots of mEPSC distribution data (E,F) from a tolerant cell.Back to article page
