Immunocytochemistry and high-performance liquid chromatography with electrochemical detection (HPLC-ED) were used, more than 76 days after infraorbital nerve (ION) transection, to examine the distribution and density of serotonin-immunoreactive (5-HTIR) axons, as well as serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) content, within the infraorbital (IO) regions of subnuclei caudalis (SpVc) and interpolaris (SpVi). In SpVi, increases in 5-HT concentration and in density of 5-HTIR axonal varicosities were observed on the lesioned side. No changes were seen in SpVc.
