description

After in vivo application of radiolabelled choline, radioactive ACh is formed and can be released from the brain by electrical stimulation. However, its origin is still obscure because, due to the metabolical heterogeneity of synaptic vesicles, no subcellular compartment has been found with a specific activity (SA) corresponding to that of released transmitter. To bypass this heterogeneity problem, two different labelled precursors can be used.
