Journal ArticleDOI
Dynamic reconfiguration of the default mode network during narrative comprehension
Erez Simony,Christopher J. Honey,Janice Chen,Olga Lositsky,Yaara Yeshurun,Ami Wiesel,Uri Hasson +6 more
TL;DR: Inter-subject functional correlation (ISFC), which isolates stimulus-dependent inter-regional correlations between brains exposed to the same stimulus, is introduced, which opens new avenues for linking brain network dynamics to stimulus features and behaviour.
Journal ArticleDOI
Neural pattern change during encoding of a narrative predicts retrospective duration estimates
Olga Lositsky,Janice Chen,Daniel Toker,Christopher J. Honey,Michael Shvartsman,Jordan Poppenk,Uri Hasson,Kenneth A. Norman +7 more
TL;DR: These findings provide convergent support for the hypothesis that retrospective time judgments are driven by 'drift' in contextual representations supported by the medial temporal lobes and prefrontal cortex.

Narratives: fMRI data for evaluating models of naturalistic language comprehension
Samuel A. Nastase,Yun-Fei Liu,Hanna Hillman,Asieh Zadbood,Liat Hasenfratz,Neggin Keshavarzian,Janice Chen,Christopher J. Honey,Yaara Yeshurun,Mor Regev,Mai Nguyen,Claire H.C. Chang,Christopher Baldassano,Olga Lositsky,Erez Simony,Erez Simony,Michael Chow,Yuan Chang Leong,Paula P. Brooks,Emily Micciche,Gina Choe,Ariel Goldstein,Tamara Vanderwal,Yaroslav O. Halchenko,Kenneth A. Norman,Uri Hasson +25 more
TL;DR: The Narratives collection as discussed by the authors collects a variety of functional MRI datasets collected while human subjects listen to naturalistic spoken stories and provides rich metadata, preprocessed versions of the data ready for immediate use and the spoken story stimuli with time-stamped phoneme-and word-level transcripts.
Journal ArticleDOI
The "Narratives" fMRI dataset for evaluating models of naturalistic language comprehension.
Samuel A. Nastase,Yun-Fei Liu,Hanna Hillman,Asieh Zadbood,Liat Hasenfratz,Neggin Keshavarzian,Janice Chen,Christopher J. Honey,Yaara Yeshurun,Mor Regev,Mai Nguyen,Claire H.C.

Halchenko,Kenneth A. Norman,Uri Hasson +25 more
TL;DR: The Narratives collection as mentioned in this paper collects a variety of functional MRI datasets collected while human subjects listen to naturalistic spoken stories, including 345 subjects, 891 functional scans, and 27 diverse stories of varying duration.
Journal ArticleDOI
Differential assessment of frontally-mediated behaviors between self- and informant-report in patients with obsessive-compulsive disorder following gamma ventral capsulotomy
Michelle T. Kassel,Olga Lositsky,Avinash R. Vaidya,David Badre,Paul Malloy,Benjamin D. Greenberg,Richard Marsland,Georg Norén,Anna Sherman,Steven A. Rasmussen,Nicole C.R. McLaughlin +10 more
TL;DR: This article investigated changes in frontally-mediated behaviors, measured by the Frontal Systems Behavior Scale (FrSBe), following gamma ventral capsulotomy (GVC) in 45 individuals with severe and otherwise intractable OCD, as rated by patients themselves and family members.
