Activation of Glycine and Extrasynaptic GABA_A Receptors by Taurine on the Substantia Gelatinosa Neurons of the Trigeminal Subnucleus Caudalis

Figure 6

Taurine-induced inward current is sensitive to picrotoxin on SG neurons. (a), (c), (e) The representative traces showing currents evoked by 100 μM and 1,000 μM taurine were blocked by picrotoxin 50 μM and 300 μM. (b), (d), (f) Comparison of mean inward current changed by taurine alone with taurine in the presence of picrotoxin (*𝑃<0.05, **𝑃<0.01). Holding potential was −60 mV.
