Increased neuronal excitability and seizures in the Na(+)/H(+) exchanger null mutant mouse.

Abstract excerpt

Mice lacking the Na(+)/H(+) exchanger isoform 1 (NHE1) manifest neurological diseases that include ataxia, motor deficits, and a seizure disorder. The molecular basis for the phenotype has not been clear, and it has not been determined how the lack of NHE1 leads, in particular, to the seizure disorder. We have shown in this work that hippocampal CA1 neurons in mutant mice have a much higher excitability than in...
