The effect of benzolamide on NH4+-induced pHi transients in cultured mouse hippocampal neurons. The effect of benzolamide on NH4+-induced pHi transients in cultured mouse hippocampal neurons. A, Example of typical sequence of pHi transients elicited by a 5 min exposure to 20 mm NH4+ (for details, see text). B, Amplification of the NH4+-induced alkalinization (NIA) by benzolamide (10 μm in all experiments). The NIA is shown in bold for all figures. Nataliya Svichar et al. J.
