| Abstract: | After injecting Fluoro-gold (FG) and tetramethylrhodamine-dextran amine (TMR-DA), respectively, into the medial part of the ventrobasal thalamus and the upper segments of the cervical cord of the rat, a small number of neuronal cell bodies were double-labeled retrogradely with both FG and TMR-DA in the parabrachial nuclear complex (PBN) ipsilateral to the injection into the thalamus. The cell bodies double-labeled with FG/TMR-DA were seen mainly in the Kölliker-Fuse subnucleus and additionally in the external medial subnucleus. |
