library_construction_protocol: Hamster cerebellum slices were collected in 350 µL of TRI reagent (Euromedex) with two stainless steel beads and lysed using a TissueLyserII (Qiagen) at Vmax for 10 min. RNA was extracted using Direct-zol RNA Miniprep Kits (Zymo Research). DNA library construction, sequencing and data analysis described in these sections were performed by Microsynth AG (Balgach, Switzerland). Total RNA was quantified using Quant-iT RiboGreen (Thermofisher) and integrity was checked on Fragment analyzer (Agilent) with a kit suitable for RNA. Library Preparation was done using the Illumina® Stranded mRNA Prep, Ligation and 60 ng total RNA input. Final libraries were quantified using pico488 (Lumiprobe) and library size was checked on Fragment analyzer (Agilent). Samples were pooled equimolar prior to sequencing. Subsequently the Illumina NovaSeq platform and an SP, 300 cycles kit were used to sequence the libraries in paired-end fashion.
