- claim_text
Conditional deletion of Lhx2 in postmitotic mouse cortical neurons preserves initial L4 specification but blocks barrel formation and L4 dendritic polarization; thalamocortical axons reach the barrel cortex but fail to arborize, and Lhx2 directly induces Btbd3 to confer activity-dependent dendritic competence for L4 circuit assembly.
