Figure 4From: Enhancement of presynaptic glutamate release and persistent inflammatory pain by increasing neuronal cAMP in the anterior cingulate cortexPresynaptic action of octopamine in transgenic mice. (A) Representative traces (upper) and pooled results (lower) showing that octopamine significantly decreased pair-pulse facilitation in transgenic mice. (B) Octopamine (50 μM) had no effect on puff-applied glutamate-induced current in transgenic mice.Back to article page
