COLLATERAL PROJECTIONS TO BOTH CAUDAL SUBNUCLEUS OF SPINAL TRIGEMINAL NUCLEUS AND NUCLEUS OF THE SOLITARY TRACT FROM THE NEURONS IN TRIGEMINAL GANGLION OF THE RAT
The technique of double labeled fluorescent tracing was used to determine whether the projections to the nucleus of the solitary tract(NTS) and caudal subnucleus of spinal trigeminal nucleus(VC)from the neurons in the trigeminal ganglion(VG)via axon collaterals.After Fast blue(FB)and Nuclear yellow(NY)were injected into VC and NTS,respectively,varied labeled neurons in VG were found under the fluorescence microscope(360nm excitation wavelength).FB displayed a blue fluorescent cytoplasm and NY appeared gold ...
