Figure Lengend Snippet: A ) Diagram of pharmacological treatment timeline (below) and associated periods of mEPSC analysis (top). After establishing whole-cell voltage-clamp recording of an individual lamina I neuron, a control aCSF period was recorded, followed by subsequently adding 1 µM Ro25-6981, then 10 µM DQP-1105, and finally 10 µM TCN-201. B) Histograms of the proportion of mEPSCs in each decay constant bin during administration of control aCSF (left), 1 µM Ro25-6981 to block GluN2B NMDARs (middle left), 1 µM Ro25-6981 + 10 µM DQP-1105 to block GluN2B and GluN2D NMDARs (middle right), and 1 µM Ro25-6981 + 10 µM DQP-1105 + 10 µM TCN-201 to block GluN2B, GluN2D, and GluN2A NMDARs.
Article Snippet: Pharmacology experiments were performed by acutely perfusing selective NMDAR antagonists onto a slice, following the control ACSF period. (αR,βS)-α-(4-Hydroxyphenyl)-β-methyl-4-(phenylmethyl)-1-piperidinepropanol maleate (Ro25-6981) , 4-(5-(4-bromophenyl)-3-(6-methyl-2-oxo-4-phenyl-1,2-dihydroquinolin-3-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-oxobutanoic acid (DQP-1105) , and (3-chloro-4-fluoro-N-[(4-([2-(phenylcarbonyl)hydrazino]carbonyl) phenyl)methyl]benzene-sulfonamide) (TCN-201) ( )were obtained from Tocris Bioscience.
