In the present study we ask whether OL production is also required for non-motor learning and cognition, using T-maze and radial-arm-maze tasks that tax spatial working memory. We find that maze training stimulates OLP proliferation and OL production in the medial prefrontal cortex (mPFC), anterior corpus callosum (genu), dorsal thalamus and hippocampal formation of adult male mice; myelin sheath formation is also stimulated in the genu. Genetic blockade of OL differentiation and neo-myelination in Myrf conditional-knockout mice strongly impairs training-induced improvements in maze performance. We find a strong positive correlation between the performance of individual wild type mice and the scale of OLP proliferation and OL generation during training, but not with the number or intensity of c-Fos+ neurons in their mPFC, underscoring the important role played by OL lineage cells in cognitive processing. date: 2023-10-14 date_type: published official_url: https://doi.org/10.1038/s41467-023-42293-4 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2097113 doi: 10.1038/s41467-023-42293-4 medium: Electronic pii: 10.1038/s41467-023-42293-4 lyricists_name: Li, Huiliang lyricists_name: Richardson, William lyricists_name: Grist, Matthew lyricists_name: Nayar, Stuart lyricists_id: HLIXX97 lyricists_id: WDRIC46 lyricists_id: MGRIS74 lyricists_id: SNAYA54 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Nature Communications volume: 14 article_number: 6499 event_location: England issn: 2041-1723 citation: Shimizu, Takahiro; Nayar, Stuart G; Swire, Matthew; Jiang, Yi; Grist, Matthew; Kaller, Malte; Sampaio Baptista, Cassandra; ...
