Specifically, the direction of smooth\npursuit phases in optokinetic nystagmus (OKN) typically corresponds to the\ndirection of motion that dominates perceptual appearance at any given time.\nHere we report an improved analysis that continuously estimates perceived\nmotion in terms of `cumulative smooth pursuit'. In essence, smooth pursuit\nsegments are identified, interpolated where necessary, and joined\nprobabilistically into a continuous record of `cumulative smooth pursuit'\n(i.e., a probability of eye position disregarding blinks, saccades, signal\nlosses, and artefacts). The analysis is fully automated and robust in healthy,\ndevelopmental, and patient populations. To validate reliability, we compare\nvolitional reports of perceptual reversals in rivalry displays, and of physical\nreversals in non-rivalrous control displays. `Cumulative smooth pursuit'\ndetects physical reversals and estimates eye velocity more accurately than\nexisting methods do (Frassle et al., 2014). It also appears to distinguish\ndominant and transitional perceptual states, detecting changes with a precision\nof $\\pm100\\,\\mathit{ms}$. We conclude that `cumulative smooth pursuit'\nsignificantly improves the monitoring of binocular rivalry by means of\nrecording OKN.","url_abs":"http://arxiv.org/abs/1812.02478v1","url_pdf":"http://arxiv.org/pdf/1812.02478v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"perceptual-reversals-in-binocular-rivalry","repo_url":"https://github.com/cognitive-biology/Cumulative-smooth-pursuit-analysis-of-BR-OKN","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
