In addition, these findings support the hypothesis that ventral telencephalic neurons and their axons guide TCAs through ventralthalamus and into ventral telencephalon.

Neural Shh is essential for the development of the prethalamus ( ventralthalamus), but its effects on the thalamus (dorsal thalamus) are still unclear.

A proportion of TCAs do extend further distally into ventralthalamus, but many of these stall at an aberrant, abrupt border of high RPTP(delta) expression.
