This study examined the impact of controlled PMI on myelin integrity in rhesus macaque brain tissue using advanced optical imaging approaches. Brains from five aged rhesus macaques (20.5\u201328.5\u2009years) were maintained at 4\u00b0C and analyzed at 0, 24, and 72\u2009h postmortem. Myelin integrity in white and gray matter was assessed using quantitative birefringence microscopy to measure relative retardance and polarization\u2010sensitive optical coherence tomography to quantify scattering coefficients, retardance, and volumetric features. Increasing PMI was associated with progressive myelin degradation, reflected by significant reductions in relative optical retardance in white matter (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01) and gray matter (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001), alongside increased scattering coefficients in both regions (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001).

These findings demonstrate that PMI causes significant detectable myelin changes, which can be quantified using optical imaging techniques, providing critical implications for interpreting postmortem neuropathological studies (especially with human brain tissues) and establishing a need for standardized PMI considerations in research protocols to ensure accurate pathological assessment in neurological disease investigations.\n                  <\/jats:p>","DOI":"10.1111\/bpa.70158","type":"journal-article","created":{"date-parts":[[2026,10,17]],"date-time":"2026-10-17T05:47:11Z","timestamp":1792216031000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of postmortem interval on myelin integrity in rhesus macaque brain tissue"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2798-6573","authenticated-orcid":false,"given":"Anna","family":"Novoseltseva","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6359-7874","authenticated-orcid":false,"given":"Rhiannon","family":"Robinson","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Neurobiology Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Niziolek","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Psychological and Brain Sciences Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2405-3136","authenticated-orcid":false,"given":"Ankita","family":"Tiwari","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5120-8133","authenticated-orcid":false,"given":"Ayman","family":"Abdelhakeem","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3501-6067","authenticated-orcid":false,"given":"Raymond","family":"Nicks","sequence":"additional","affiliation":[{"name":"Chobanian &amp; Avedisian School of Medicine Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yvonne","family":"Lucas","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Neurobiology Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3658-1375","authenticated-orcid":false,"given":"Qiong","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Public Health Biostatistics Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1911-5428","authenticated-orcid":false,"given":"Farzad","family":"Mortazavi","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Neurobiology Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Boas","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering Boston University  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Athinoula A.
