Volume changes in neurons: hyperexcitability and neuronal death.

Abstract

Hyponatremia propitiates and increases susceptibility to seizure episodes. In vitro, hyposmolarity induces hyperexcitability and epileptiform activity and increases the amplitude of excitatory postsynaptic potentials. Synaptic (increased glutamate vesicular release) and non-synaptic (swelling-induced extracellular space shrinkage and ephaptic interactions… (More)
