The high level expression in the midbrain is anterior to the midbrain-hindbrain boundary defined by Wnt1 expression, but expression overlaps with Wnt1 in the ventral midbrain.
Expression is in a sharp-narrow band in the region of the midbrain-hindbrain junction (isthmus). This does not include cells of the ventral midline. Expression is immediately caudal to Wnt1 expression.

Expression was detected in a dorsal position in a region lateral to the roof plate. Compared to adjacent sections, there is a partial overlap of the expression pattern with Wnt1 and Lhx2 in the caudal region.
