Kurzfassung:
The overall distribution of substance P‐like immunoreactivity (SPI) in the wall of the cerebral arteries and their origins were investigated in the guinea pig by using whole‐mounts. Two types of SPI fibers were seen: one forming dense fiber bands and lo‐cated among the periadventitial nerves, and the other forming a meshwork. The SPI fibers located in the periadventitial nerves often leave these nerves to form a meshwork of SPI fibers of varying density according to the diame‐ter or location of the blood vessels. The present study suggests that: (1) SPI fibers located on the circle of Willis and its branches originate from SPI cells in the trigeminal ganglion; (2) SPI fiber's of the rostral one‐third of the basilar artery originate partly from trigeminal SPI cells; and (3) SPI fibers in the caudal two‐thirds of the basilar artery originate exclusively from other SPI cells, apart from the tri‐geminal ganglion.
