title: Distribution of substance P-like immunoreactive structures in the brainstem of the adult human brain: an immunocytochemical study.
abstract: The distribution of substance P-like immunoreactive (SPI) structures in the brainstem of the adult human was investigated by the avidin-biotinylated peroxidase complex method for immunocytochemistry. SPI structures were widely distributed in the brainstem, and particularly dense in the substantia nigra, peripheral portions of the colliculus inferior, central gray matter, parabrachial area, nucleus dorsalis tegmenti of Gudden, nucleus reticularis tegmenti pontis, nucleus tractus solitarii, nucleus dorsalis motorius nervi vagi, and nucleus tractus spinalis nervi trigemini.
