Fig. 8. Neural connection between lamprey parapinopsin-containing cells and
ganglion cells by confocal imaging. The basal processes of lamprey
parapinopsin-containing cells (green) are extended to and directly connect
with ganglion cells (magenta) in the peripheral (A,B) and dorsal (C,D)
regions. The single optical section (inset in A), which was taken by confocal
laser-scanning microscopy, reveals that the varicosity-like structure and
spherules of the lamprey parapinopsin immunoreactive process contact the
ganglion cells. The arrows and arrowheads show the contact points. l, lumen.
