External calcium, intrasynaptosomal free calcium and neurotransmitter release.


In a physiological medium the resting membrane potential of synaptosomes from guinea-pig cerebral cortex, estimated from rhodamine 6G fluorescence measurements, was nearly -50mV. This agreed with calculations using the Goldman-Hodgkin-Katz equation. With external [Ca2+] less than or equal to 3 mM veratridine depolarisation (to -30 mV) was accompanied by… (More)
