Transsynaptic Fish-lips signaling prevents misconnections between nonsynaptic partner olfactory neurons.

abstract：:Hippocampal mossy fibers, which are the axons of dentate granule cells, form powerful excitatory synapses onto the proximal dendrites of CA3 pyramidal cells. It has long been known that high-affinity binding sites for kainate, a glutamate receptor agonist, are present on mossy fibers. Here we summarize recent experime...
