Helical structure of the cytoskeleton in the axoplasm and dendroplasm of olfactory bulb neurons after functional re-innervation in goldfish.
An ultrastructural study was carried out of the cytoskeleton arrangement of neuronal and glial processes in the olfactory bulbs and the olfactory tracts of intact and operated goldfish. Ripple patterns of bundles formed by both microtubules and intermediated filaments (neurofilaments and glial filaments) suggest that the cytoskeleton of olfactory cell processes has a helical arrangement. One year after bilateral olfactory tract transection complete recovery in the ultrastructure of the medial and lateral subtracts was observed. The obtained results are interpreted as reflecting the inherent helicity of the cytoskeleton of the olfactory cell processes.
