Does bouton morphology optimize axon length

摘要: The total length of cortical axons could be reduced if the parent maintained straight trajectories and simply connected to dendritic shafts via spine-like terminaux boutons spines bead-like en passant boutons. Cortical from cat area 17 were reconstructed serial electron micrographs their bouton morphology was correlated with synaptic targets. En or did not differ in proportion synapses they formed shafts, thus, two morphological variants do contribute directly optimizing axon length.
