Here, we investigate how perisaccadic temporal information is encoded and read out in extrastriate cortex, by combining electrophysiological recordings in V4 and MT neuronal population in macaque monkeys under high spatiotemporal resolution visual stimulation, and a statistical modeling framework capturing perisaccadic response modulations at single-trial precision. Our analyses show that perisaccadic neuronal responses systematically shift the temporal representation of presaccadic stimuli within receptive fields\u2013biasing them toward earlier times, and also reduce temporal sensitivity for presaccadic stimuli\u2013impairing discrimination of stimulus onset times. Model-based readout using time-varying spatiotemporal sensitivity maps in neuronal ensembles enables quantitative characterization of these effects and identifies their specific neuronal response components at millisecond resolution. In silico manipulations further demonstrate a causal role of representational bias in reducing temporal sensitivity. These findings suggest that extrastriate cortex implements an active encoding strategy to stabilize presaccadic temporal information by favoring the most recent reliable input, revealing a fundamental tradeoff between temporal precision and robustness that supports a continuous visual percept across saccades. This finding also establishes a general role for extrastriate populations in constructing the perception of visual time.<\/jats:p>","DOI":"10.64898\/2026.06.16.732385","type":"posted-content","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T00:20:24Z","timestamp":1782174024000},"source":"Crossref","is-referenced-by-count":0,"title":["A population readout of extrastriate activity reveals biased and smoothed temporal representations across saccades"],"prefix":"10.64898","author":[{"given":"Adeleh","family":"Poursadegh","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Isfahan University of Technology, Isfahan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Zekri","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Isfahan University of Technology, Isfahan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geyu","family":"Weng","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Utah, Salt Lake City, UT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amir","family":"Akbarian","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Utah, Salt Lake City, UT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelsey","family":"Clark","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Utah, Salt Lake City, UT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hossein","family":"Rabbani","sequence":"additional","affiliation":[{"name":"Department of Bioelectrics and Biomedical Engineering, School of Advanced Technologies in Medicine, Isfahan University of Medical Sciences, Isfahan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Behrad","family":"Noudoost","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Utah, Salt Lake City, UT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neda","family":"Nategh","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Utah, Salt Lake City, UT, USA"},{"name":"Department of Ophthalmology and Visual Sciences, University of Utah, Salt Lake City, UT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2026062408001441000_2026.06.16.732385v1.1","first-page":"301","article-title":"Time perception: A review on psychological, computational, and robotic models","volume":"14","year":"2021","journal-title":"IEEE Trans.
