TLDR
Arecoline increased both the activity of K+-phosphatase in incubated synaptosomal fractions and the (Na+ + K+)-ATPase activity of synaptOSomal membranes by 40% and 78%, respectively, which is believed to be associated with increased ACh synthesis produced by arecoline.
Abstract
Synaptosomal fractions and synaptosomal membranes from rat brain tissue were prepared and characterized enzymatically. Arecoline increased both the activity of K+-phosphatase in incubated synaptosomal fractions and the (Na+ + K+)-ATPase activity of synaptosomal membranes by 40% and 78%, respectively. This activation of ion transport processes is believed to be associated with increased ACh synthesis produced by arecoline.

Na+–K+-ACTIVATED ADENOSINETRIPHOSPHATASE AS A TRIGGER IN TRANSMITTER RELEASE

TL;DR: This chapter discusses the hypothesis that under physiological conditions, the influx of calcium ions and the subsequent inhibition of membrane ATPase were postulated to be the trigger for the release of neurotransmitter.

Behavioral, physiological, and neuroendocrine responses to arecoline in normal twins and “well state” bipolar patients

TL;DR: Mood, behavioral, and neurochemical responses to arecoline, which appears to have nonspecific neurochemical effects at the dose employed, are not markers of vulnerability to affective illness.

Arecoline-induced elevations of regional cerebral metabolism in the conscious rat.

TL;DR: Elevations in LCGU (measured after [14C]DG injection during peak behavior) in extrapyramidal regions, which mediate tremor, were related to the intensity of tremor and demonstrates the high sensitivity of this region to cholinomimetic stimulation.

Increased ouabain binding after repeated noradrenergic stimulation

TL;DR: Prazosin, which, like piperoxane, activates presynaptic noradrenergic neurons but, unlike piper oxane, blocks postsynaptic receptors, did not increase K+-p-nitrophenylphosphatase, and decreased ouabain binding after 3 weeks.
