Four genes\u2014\n                    <jats:italic>Fezf2, Ctip2, Tbr1<\/jats:italic>\n                    , and\n                    <jats:italic>Satb2<\/jats:italic>\n                    \u2014regulate these projection identities. These genes also interact with each other, and it is unclear how these interactions shape the final projection identity. Here we show, by generating double mutants of\n                    <jats:italic>Fezf2, Ctip2<\/jats:italic>\n                    , and\n                    <jats:italic>Satb2<\/jats:italic>\n                    , that cortical neurons deploy a complex genetic switch that uses mutual repression to produce subcortical or callosal projections. We discovered that\n                    <jats:italic>Tbr1, EphA4<\/jats:italic>\n                    , and\n                    <jats:italic>Unc5H3<\/jats:italic>\n                    are critical downstream targets of Satb2 in callosal fate specification. This represents a unique role for\n                    <jats:italic>Tbr1<\/jats:italic>\n                    , implicated previously in specifying corticothalamic projections. We further show that Tbr1 expression is dually regulated by\n                    <jats:italic>Satb2<\/jats:italic>\n                    and\n                    <jats:italic>Ctip2<\/jats:italic>\n                    in layers 2\u20135.
