Exocytotic Release of [3H]-Acetylcholine by Ouabain Involves Intracellular Ca2+ Stores in Rat Brain Cortical Slices.

Investigates the effect of ouabain on the release of [[sup 3]H]acetylcholine ([[sup 3]H]ACh) in rat brain cortical slices. Evidence that the ouabain-induced release of ([[sup 3]H]ACh) was calcium-independent and not blocked by EGTA; Suggestion that ouabain causes Ca[sup 2+] release from intracellular stores that can increase ([[sup 3]H]ACh) exocytosis from rat brain cortical slices.
