TS23: fasciculus retroflexus	Present	Regionally restricted	3A	Expressed in segregated medial habenular fasciculus retroflexus axons, which placed tightly in the core.

Structure	Level	Pattern	Image	Note
TS23: fasciculus retroflexus	Present		3B	The tract was wide, and even divided in two fascicles in the mutant embryos and the axons were less fasciculated.

TS23: fasciculus retroflexus	Present	Regionally restricted	4A"	Expressed in segregated medial habenular fasciculus retroflexus axons, which placed tightly in the core.

Structure	Level	Pattern	Image	Note
TS23: fasciculus retroflexus	Present	Regionally restricted	4B	Expressed in segregated medial habenular fasciculus retroflexus axons, which placed tightly in the core. In a mild case, the tract was less compacted and generated unilateral aberrant duplications.

Structure	Level	Pattern	Image	Note
TS23: fasciculus retroflexus	Present	Regionally restricted	4C	In a severe case, the tract was much wider. Positive axons stayed in the core.
