From theCambridge English Corpus From the peripheral retina, where there is little fasciculation, axons converge on the optic disc. From theCambridge English Corpus Although far less frequent, some axons were seen to be ensheathed by an oligodendrocytic process; such axons were counted as 'myelinated'. From theCambridge English Corpus Myelinated axons are organized into a series of polarized domains that are crucial for normal saltatory conduction. From theCambridge English Corpus Regressive events such as cell death and the elimination of longaxoncollaterals and dendritic processes are essential mechanisms of brain maturation. From theCambridge English Corpus Each pattern is broadcast through the brain by divergent-convergentaxonprojections. From theCambridge English Corpus When conventional symmetrical biphasic pulses were used, there was little selectivity between activation of local cells and activation of axons of passage. From theCambridge English Corpus As a result, the nodal length in larger axons (>1 mm) is significantly reduced in transgenic mice compared with their wild-type littermates. From theCambridge English Corpus Serial electron microscopic reconstruction ofaxonterminals on physiologically identified thalamcortical neurons in the cat ventral lateral nucleus. From theCambridge English Corpus During early regrowth only a few axons entered an otherwise complete connective-tissue bridge. From theCambridge English Corpus However, regulation of their expression levels suggests a role for both proteins duringaxongrowth in the visual pathway. From theCambridge English Corpus These small concentrations and the diffuse labeling appeared in a linear orientation as though they were aligned along anaxon. From theCambridge English Corpus Even if some connections for intermediate (1-10 mm) distances are tangential, the final synaptically active parts of the axons are vertically oriented. From theCambridge English Corpus Ionic conductance changes in lobsteraxonmembranes when lanthanum is substituted for calcium.
