N normal phenotype
behavior/neurological
N
• normal behavior and mobility in open field test
• normal behavior in marble burying test
• normal self-grooming behavior
• normal motor coordination and balance
• no increased latency to fall at days 2 and 3 in accelerated rotarod test (wild-type mice increase latency)
• no difference in interaction with novel mouse cage vs familiar mouse cage (wild-type mice spend more time with novel mouse)
• normal behavior in novel mouse cage vs empty cage test: more time spent with mouse

nervous system
• normal cortical thickness
• increased hemisphere length and cortical area at age P20
• at age P20 and in E18.5 embryos
• increased brain-to-body weight ratio
• normal cortical thickness
• increased Tbr1+ neurons in E16.5 embryos and Tbr1+ neurons and Ctip2+ neurons in E18.5 embryos
• increased Cux1+ neurons t age P20
• normal Cux1+ neurons in E18.5 embryos
• normal distribution of Tbr1+, Cux1+ and Ctip2+ neurons in embryos
• normal numbers of Tbr1+, Cux1+ and Ctip2+ neurons in E14.5 embryos
• increased Tbr1+ neurons in E16.5 embryos and Tbr1+ neurons and Ctip2+ neurons in E18.5 embryos
• increased Cux1+ neurons t age P20
• normal Cux1+ neurons in E18.5 embryos
• increased proliferation and decreased cell cycle exit of neuronal precursor cells (NPCs) in E14.5 embryos
