CATECHOLAMINES MODULATE METAMORPHOSIS 325 apical eye sensory organ \ \ velum £ cerebral ganglion propodium «| pedal ganglion 'operculum. digestive gland Figure 5. Tyrosine-hydroxylase-like immunoreactivity shown in projection patterns of normal larvae, reconstructed from multiple optic sections from a confocal microscope. (A) Lateral view of larva with velar lobes folded medially by mounting. A concentration of immunoreactive, subepithelial cells was labeled in the propodium. These cells appeared to send axons into the developing pedal ganglia. Large numbers of other cells were located along the length of the foot. Other cells were scattered near the mouth and velum, and in regions of the head near and dorsal to the apical sensory organ and eyes. (B) Magnified and more frontal view of somata (larger arrowheadsl in propodium. Many of these cells possessed processes (slender arrows) that penetrated the overlying epithelium. (C) A smaller number of somata (arrowheads) with processes (slender arrows) are located near the distal tip of the foot. Calibration bar in A equals approximately 57 ;u,m. Calibration bars in B and C equal approximate 12 /^m. larvae, the largest concentrations of fluorescent cells were again found in the propodial regions of the foot. Each of the bilateral patches contained 10 to 20 brightly fluorescent cells (Fig. 4C). In addition, several fluorescent cells were located in lateral bands along the length of the foot. At least some of these cells appeared to possess apical processes extending through the overlying epithelium (Fig. 4D). Larvae treated with either L-DOPA or L-DOPA plus a-MMT also contained many brightly fluorescent cells in the head region. Several cells were routinely observed around the mouth, near the base of the velum (Fig. 4C), and anterior to the eyes. Thus the distribution of the cells in head regions was similar to that observed in normal larvae and in tho
