Such methods are particularly problematic in posterior cortical regions (e.g. visual cortex), where sectioning leads to significant damage and distortion of tissue. Even more challenging is the post hoc localization of micro-electrodes, which relies on the same techniques, suffers from similar drawbacks and requires even higher precision. Here, we propose a new, simple method for quantitative lesion characterization and electrode localization that is less labor-intensive and yields more detailed results than conventional methods. We leverage staining techniques standard in electron microscopy with the use of commodity micro-CT imaging. We stain whole rat and zebra finch brains in osmium tetroxide, embed these in resin and scan entire brains in a micro-CT machine. The scans result in 3D reconstructions of the brains with section thickness dependent on sample size (12–15 and 5–6 microns for rat and zebra finch respectively) that can be segmented manually or automatically. Because the method captures the entire intact brain volume, comparisons within and across studies are more tractable, and the extent of lesions and electrodes may be studied with higher accuracy than with current methods.","lang":"eng"}],"date_created":"2018-12-11T11:46:19Z","license":"https://creativecommons.org/licenses/by/4.0/","language":[{"iso":"eng"}],"isi":1,"article_processing_charge":"No","has_accepted_license":"1","article_number":"5184","day":"26","publication_status":"published","quality_controlled":"1","date_updated":"2023-09-08T11:48:39Z","date_published":"2018-03-26T00:00:00Z","intvolume":"         8","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"author":[{"last_name":"Masís","first_name":"Javier","full_name":"Masís, Javier"},{"full_name":"Mankus, David","first_name":"David","last_name":"Mankus"},{"last_name":"Wolff","first_name":"Steffen","full_name":"Wolff, Steffen"},{"full_name":"Guitchounts, Grigori","first_name":"Grigori","last_name":"Guitchounts"},{"full_name":"Jösch, Maximilian A","orcid":"0000-0002-3937-1330","last_name":"Jösch","id":"2BD278E6-F248-11E8-B48F-1D18A9856A87","first_name":"Maximilian A"},{"full_name":"Cox, David","first_name":"David","last_name":"Cox"}],"type":"journal_article","oa_version":"Published Version","status":"public","pubrep_id":"994","publication":"Scientific Reports","ddc":["571","572"],"volume":8,"year":"2018","scopus_import":"1","citation":{"mla":"Masís, Javier, et al. “A Micro-CT-Based Method for Quantitative Brain Lesion Characterization and Electrode Localization.” <i>Scientific Reports</i>, vol. 8, no. 1, 5184, Nature Publishing Group, 2018, doi:<a href=\"https://doi.org/10.1038/s41598-018-23247-z\">10.1038/s41598-018-23247-z</a>.","apa":"Masís, J., Mankus, D., Wolff, S., Guitchounts, G., Jösch, M.
