For short-channel temporal regression, we compare non-neural signal removal using first and combined first and second PCs from a broad distribution of short channels to limited distribution on the forehead.\nResults: Temporal regression of non-neural information from broadly distributed short channels did not differ from forehead-only distribution. Spatial PC filtering provides results similar to short-channel separation using the temporal domain. Utilizing both first and second PCs from short channels removes additional non-neural information.\nConclusions: We conclude that short-channel information in the temporal domain and spatial domain regression filtering methods remove similar non-neural components represented in scalp hemodynamics from fNIRS signals and that either technique is sufficient to remove non-neural components.<\/jats:p>","DOI":"10.1117\/1.nph.8.1.015004","type":"journal-article","created":{"date-parts":[[2021,2,13]],"date-time":"2021-02-13T05:27:23Z","timestamp":1613194043000},"page":"1-22","source":"Crossref","is-referenced-by-count":41,"title":["Comparison of short-channel separation and spatial domain filtering for removal of non-neural components in functional near-infrared spectroscopy signals"],"prefix":"10.1117","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9773-2790","authenticated-orcid":false,"given":"J.
