Afferent neurons containing substance P (SP) were studied immunohistochemically in the sensory ganglion of the spinal nerve in 30 rats aged 10-90 days. The results obtained indicated that SP-immunoreactive neurons are present in thesel ganglia from the moment of birth. During the development, the percentage of SP-containing neurons decreased till day 10. SP-immunoreactive neurons were represented by the cells of very small or small size.
