TS27: auditory cortex	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI.
TS27: claustrum	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI.
TS27: insular cortex	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI.
TS27: primary motor cortex	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI.
TS27: visual cortex	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI.
TS27: frontal association cortex	Weak			Cell counting analysis of expressing cells, summarized in Fig 7D. Decreased expression compared with that of P14. Only the ratio of positive cells in the layer VI was shown, since expression was only seen in the layer VI. Most positive cells were Rbfox3/NeuN-positive neurons (see Fig 8C).
