| Abstract: | Summary Excitatory terminals, depleted of their synaptic vesicles by stimulation at high frequency, were incubated in the radiolabelled putative neurotransmitter, L-glutamate. Quantitative electron microscope autoradiography revealed that the axoplasm of these recovering terminals had accumulated the3H L-glutamate.Acknowledgment. The authors wish to thank Dr N. M. Blackett for running the computer analyses of the autoradiographical results. R. P. Botham gratefully acknowledges the SRC for financial assistance. |
