Total RNA was extracted from mouse brains following behavioral experiments using TRIZOL reagent (Thermo Fisher Scientific, USA) according to the manufacturer's instructions. Libraries were prepared using the TruSeq Stranded mRNA Library Preparation Kit (Illumina) according to the manufacturer's protocol. Sequencing was performed on an Illumina NovaSeq 6000 platform with paired-end 150 bp reads to achieve a coverage of approximately 6 Gb per sample.
