P110a
Wild type (WT) C57BL/6 male mice aged E14.5, E16.5, P0, P4, P7, P15, P30, P110 and 21 months were used for sample collection.  Total RNA was extracted from whole cortices of individual animals, with duplicates at each age.  RNA-Seq libraries were prepared using the TruSeq RNA Sample Preparation Kit (Illumina) and PE 2×101-nt reads were generated using the Illumina HiSeq 2000.
