Using spinning disk microscopy on barely day-old zebra fish
embryos, University of Oregon scientists have gained a new window on how
synapse-building components move to worksites in the central nervous system.
What researchers captured in these see-through embryos — in
what may be one of the first views of early glutamate-driven synapse formation
in a living vertebrate — were orderly movements of protein-carrying packets
along axons to a specific site where a synapse would be formed.
