Genetic and pharmacological modulation of giant depolarizing potentials in the neonatal hippocampus associates with increased seizure susceptibility.

Abstract excerpt

The expression of Na(+)-K(+)-2Cl(-) cotransporter (NKCC1) is responsible for high intracellular Cl(-) resulting in the excitatory action of GABA(A) receptor activation in the developing brain. Giant depolarizing potentials (GDPs) are spontaneous network oscillations that involve GABA(A) receptors and are thought to be important in establishing neuronal circuit wiring. Earlier work established that seizure...
