The release of labelled acetylcholine and choline from cerebral cortical slices stimulated electrically.
1 In order to establish the origin of the increased efflux of radioactivity caused by electrical stimulation of cerebral cortical slices which had been incubated with [(3)H]-choline, labelled choline and acetylcholine (ACh) collected by superfusion were separated by gold precipitation.2 In the presence of physostigmine electrical stimulation (1 Hz, 10 min) increased the release of only [(3)H]-A...

The possible involvement of phosphoinositides' turnover in the process of neurotransmitter release in the central nervous system (CNS) was studied using rat brain slices and synaptosomes. A depolarizing concentration of potassium chloride (25 mM) induces an 8.6 +/- 0.4% increase of [3H]noradrenaline [( 3H]NA) fractional release in cerebral cortical slices above spontaneous release, and 15 mM KC...
متن کاملThe Effect of Voluntary and Electrically Stimulated Quadriceps Muscle Fatigue on Postural Control
Purpose: The present study aimed to investigate the effect of voluntary and electrically stimulated quadriceps muscle fatigue on postural control. Methods: Sixteen healthy young males participated in this quasi-experimental study. All subjects performed two fatiguing exercises with equal intensity of isometric maximal voluntary contraction: Voluntary (VOL) and Electrical Stimulation (ES). The ...
