Nerve terminals («synaptosomes») isolated from rat brain hippocampus were loaded with the fluorescent Ca 2+ indicator fura-2 and were subjected to depolarization with an elevated K + concentration in a stopped-flow spectrophotometer to measure the

1. Changes of cytoplasmic free calcium levels ([Ca2+]i) in isolated rat brain nerve terminals (synaptosomes), previously loaded with the fluorescent intracellular calcium indicator Fura-2, were measured 1-2 ms after depolarization with elevated K+ by

Calcium uptake by vesicles in a highly enriched sarcolemma preparation from canine ventricle was found to be markedly stimulated by intravesicular calcium. Stimulation of calcium uptake appeared to be a saturable function of intravesicular calcium. C

Phencylidine (PCP) is a major drug of abuse in the United States. It produces a toxic confusional psychosis in man. We show here that nanomolar to micromolar concentrations of PCP and behaviorally active congeners selectively block voltage-regulated

86Rb efflux was examined in isolated presynaptic nerve terminals (synaptosomes) from rat brain in a study designed to assess K permeability (PK) changes sensitive to alterations in internal Ca activity. Rb efflux from 86Rb-loaded synaptosomes into no

In their classical study of excitability in squid axons, Hodgkin and Huxley (cf. Hodgkin, 1967) showed that the nerve action potential could be explained by selective, transient sodium (Na) and potassium (K) conductance changes that were explicitly d

86Rb efflux from pinched-off rat brain presynaptic nerve terminals (synaptosomes) was used to measure the K permeability of the terminals. Synaptosomes were pre-loaded with 86Rb and the suspensions were then filtered on glass fibre filters. The termi

Experiments were carried out to test the hypothesis that membrane depolarization stimulates Ca2+ uptake by vesicles in a sarcolemma preparation. Vesicles from a highly enriched sarcolemma preparation, previously loaded with 150 mM K+, developed a mem
