Figure 7. A, Camera lucida drawing
of frontal sections of the forebrain of
an embryo in which Dl.l.1 had been
deleted bilaterally. The brain is small
and the infundibulum is missing (compare
to Fig. 3). The DA neurons (solid
circles) are fewer in number and are distributed
along the ventralmost surface
of the brain. Hy, hypothalamus. B, A
photomicrograph of the ectopically located
DA neurons. Arrowheads point to
the ventral border of the forebrain. The
arrow points to an autofluorescent cell.
Scale bars: A, 100 um; B, 25 um. |
