Baclofen-sensitive currents in labeled PVN neurons in WKY rats and SHR. A: original tracings showing currents elicited by puff application of 100 μM baclofen to labeled PVN neurons in WKY rat and SHR. Arrows indicate puff application of baclofen. B: raw tracings showing undetectable current by puff application of 100 μM baclofen when 1 mM GDPβS was included in the recording pipette solution in WKY rats and SHR. C: summary data showing the baclofen-sensitive current elicited by puff application of 100 μM baclofen in labeled PVN neurons in WKY rats and SHR. D: summary data showing baclofen-sensitive currents in the absence and presence of 2 μM CGP-55845 (CGP) in labeled PVN neurons in WKY rats and SHR. Data are means ± SE. *P < 0.05 compared with the corresponding value in WKY rats.
