The Society of Toxicologic Pathology (STP) has published \u201cbest practices\u201d recommendations for nervous system sampling in nonrodents during general toxicity studies ( Toxicol Pathol 41[7]: 1028-1048, 2013), but their adaptation to the Beagle dog has not been defined specifically. Here we provide 2 trimming schemes suitable for evaluating the unique neuroanatomic features of the dog brain in nonclinical toxicity studies. The first scheme is intended for general toxicity studies (Tier 1) to screen test articles with unknown or no anticipated neurotoxic potential; this plan using at least 7 coronal hemisections matches the STP \u201cbest practices\u201d recommendations. The second trimming scheme for neurotoxicity studies (Tier 2) uses up to 14 coronal levels to investigate test articles where the brain is a suspected or known target organ. Collection of spinal cord, ganglia (somatic and autonomic), and nerves for dogs during nonclinical studies should follow published STP \u201cbest practices\u201d recommendations for sampling the central ( Toxicol Pathol 41[7]: 1028-1048, 2013) and peripheral ( Toxicol Pathol 46[4]: 372-402, 2018) nervous systems. This technical guide also demonstrates the locations and approaches to collecting uncommonly sampled peripheral nervous system sites.<\/jats:p>","DOI":"10.1177\/01926233221099300","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T06:46:49Z","timestamp":1655880409000},"page":"432-465","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["A Technical Guide to Sampling the Beagle Dog Nervous System for General Toxicity and Neurotoxicity Studies"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4722-9577","authenticated-orcid":false,"given":"Xavier","family":"Palazzi","sequence":"first","affiliation":[{"name":"Pfizer Inc., Groton, Connecticut, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid D.","family":"Pardo","sequence":"additional","affiliation":[{"name":"Biogen, Cambridge, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayley","family":"Ritenour","sequence":"additional","affiliation":[{"name":"Pfizer Inc., Groton, Connecticut, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8149-6401","authenticated-orcid":false,"given":"Deepa B.","family":"Rao","sequence":"additional","affiliation":[{"name":"Greenfield Pathology Services, Inc., Greenfield, Indiana, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6065-1492","authenticated-orcid":false,"given":"Brad","family":"Bolon","sequence":"additional","affiliation":[{"name":"GEMpath, Inc., Longmont, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert H.","family":"Garman","sequence":"additional","affiliation":[{"name":"Consultants in Veterinary Pathology, Inc., Murrysville, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,6,22]]},"reference":[{"key":"bibr1-01926233221099300","unstructured":"U.S. Environmental Protection Agency (EPA).
