Pipette solutions contained the following (in mM): K+ gluconate (125), NaCl (10), CaCl2 (0.5), EGTA (5), adenosine-triphosphate (magnesium salt; 4.0), guanosine-triphosphate (trisodium salt; 0.5), HEPES (5), pH 7.32, 275C282 mOsm. muscarinic or nicotinic receptors suppressed the center responses of brisk-sustained Off-cells and the center light responses of subsets of brisk-transient/G11 On- and Off-cells. Only nicotinic … Continue reading Pipette solutions contained the following (in mM): K+ gluconate (125), NaCl (10), CaCl2 (0
