Recent studies show that several fluorescent substances are transported retrogradely through axons to their parent cell bodies and label in different colors different features of the cell at the same 360 nm excitation wavelength. Thus, Bisbenzimide (Bb) and “Nuclear Yellow” (NY; Hoechst S 769121) produce green and golden-yellow retrograde labeling of the(More)
Bisbenzimide and Hoechst S 769121 (Nuclear Yellow, NY), when transported retrogradely through axons to their parent cell bodies, may migrate out of the axons and the cell bodies, as indicated by fluorescence of adjoining glial nuclei. This migration was found to take place both in vivo and in vitro during storage of the sections in water. When using the(More)
Two new fluorescent retrograde neuronal tracers are reported: Nuclear Yellow (Hoechst S 769121), which mainly labels the neuronal nucleus; and Fast Blue (diamidino compound 253/50), which mainly labels the neuronal cytoplasm. Both tracers appear to be transported effectively over long distances in rat and cat.
In rat the presence of axon collaterals from corticospinal neurons to the contralateral hemisphere has been investigated by means of anatomical and electrophysiological techniques. Anatomical Experiments. Several combinations of fluorescent retrograde tracers were used. In eight rats injections of Evans Blue, “True Blue”, “Fast Blue” or DAPI-Primuline were(More)
Six fluorescent substances, binding specifically to adenine-thymine rich DNA, were injected in rat caudate-putamen. This resulted in retrograde axonal transport and fluorescent retrograde labeling of neurons in center-medium parafascicular nucleus, substantia nigra and dorsal raphe. Two of these substances, i.e. "True Blue' and 'Granular Blue', give a very(More)
An attempt has been made to determine anatomically whether in rat and cat cortical projections to ventrolateral nucleus of thalamus and to mesencephalon are in part composed of corticospinal collaterals. For this purpose two different fluorescent tracers were injected: one in the spinal cord and the other contralaterally in the lateral thalamus and in the(More)
Two fluorescent substances bisbenzimide (Bb), which fluoresces yellow-green and propidium iodide (PI), which fluoresces orange were found to be transported retrogradely through axons to their parent cell bodies in rat and cat. Bb gives a very strong and long lasting fluorescent retrograde neuronal labeling and is very effectively transported over long(More)
