Presynaptic Glycine Receptors Increase GABAergic Neurotransmission in Rat Periaqueductal Gray Neurons
Figure 3
Effect of strychnine on glycine-induced increase in sEPSC frequency. (a) Typical traces of glutamatergic sEPSCs observed during the application of 100 μM glycine in the absence (upper) and presence (lower) of 1 μM strychnine. (b) Glycine-induced changes in frequency (A) and amplitude (B) of sEPSC in the absence and presence of strychnine. Each column was the mean and SEM from 6 neurons. **; n.s.: not significant.
