Fig. 4. Comparison of the localization of lamprey parapinopsin-containing cells
with that of lamprey rhodopsin-containing cells in the pineal organ. (A)
Schematic drawing of the top view of the pineal organ. The horizontal lines
show the position of the sections of B and C. (B) In the cross-section around
the peripheral portion (about 200 µm rostrally from the centre), there are
more lamprey parapinopsin-containing cells (green) than lamprey
rhodopsin-containing cells (red). (C) In the cross-section around the central
portion, there are fewer lamprey parapinopsin-containing cells (green) than
lamprey rhodopsin-containing cells (red). There are more lamprey
parapinopsin-containing cells in the peripheral portion than in the central
portion. l, lumen; p, pineal organ; ps, pineal stalk. Scale bars, 100
µm.
