Uptake and Storage of 3H-Norepinephrine in the Cerebral Hemispheres and Cerebellum of Chicks during Embryonic Development and Early Posthatching
Intercommunication between neurons involves neurotransmitter substances which: (a) are synthesized and stored in the presynaptic neuron, (b) are released by the arrival of the impulse; and (c) act on the postsynaptic neurons. The molecular events occurring presynaptically, at the synaptic cleft, or on the postsynaptic membrane are among the most intensively studied subjects in neurobiology. Whereas considerable knowledge exists about the adult CNS, information concerning the differentiation of neurotransmisstion mechanisms during development has only recently begun to accumulate.
