TS26: brain fiber tract	Present	Regionally restricted	10A , 10A'	Expression was detected in the corticofugal axons and thalamocortical axons.
TS26: thalamocortical tract	Present	Regionally restricted	10A , 10A'	Expression was detected in the corticofugal axons and thalamocortical axons.

Structure	Level	Pattern	Image	Note
TS26: brain fiber tract	Present	Regionally restricted	10B , 10B'	Expression was detected in the corticofugal axons and thalamocortical axons. Corticofugal axons poorly innervated the internal capsule, and thalamocortical axons were nearly lost before reaching the internal capsule. A majority of the fibers abnormally descended into the hypothalamus.
