Inhibition of 45Ca movements by lowered temperature or lanthanum in rat brain slices.


Different components of 45Ca movements in rat cortex, striatum and hypothalamus slices were delineated by conditions and ions which selectively alter Ca2+ uptake, binding or extrusion. Equilibration of 45Ca was qualitatively similar in all three tissues and was attained within 30--60 min. The 45Ca tissue-medium ratios obtained in 1.5 mM Ca2+ solutions were… (More)
