Potassium current in Drosophila neurons is increased by either dunce mutation or cyclic AMP.

Journal of neuroscience research - 1 Jun 1998

Alshuaib W B, Mathew M V

Abstract excerpt

In the Drosophila mutant dunce, short-term memory is deficient and intracellular cyclic adenosine monophosphate (cAMP) concentration is elevated. We examined the effect of increased cAMP concentration on the potassium current. The conventional whole-cell technique was applied to cultured "giant" Drosophila neurons derived from cell-division arrested embryonic neuroblasts. Potassium membrane currents were measured...
