Figure 4.
Role of TCF7L2 in the developing thalamus and habenula. Early knockout of Tcf7l2 impairs segregation of cells in the thalamo‐habenular primordium (upper and middle panel), and disrupts axon growth and regional cell identities (middle panel). Conditional postnatal knockout of Tcf7l2 impairs intrinsic excitability of thalamo‐cortical relay neurons (bottom panel).
