Although total sleep deprivation appears rare, habitual short sleep is common: 30% of working US adults report habitually sleeping \u2264 6 hours\/night. It remains largely unknown whether habitual short sleepers exhibit similar reward processing brain activation patterns to those observed following total sleep deprivation in prior studies. Therefore, our aim was to test objectively reward processing brain activation patterns associated with self-reported habitual short sleep duration in a large sample.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Nine hundred and fifty-two adult participants from the Human Connectome Project database were grouped on reported habitual short (\u22646 hours) vs. medium-length (7\u20139 hours) sleep duration using the Pittsburgh Sleep Quality Index (PSQI). Reward processing brain activation was examined using a gambling task during functional magnetic resonance imaging (fMRI). Subject-level covariates for age, sex, continuous sleep duration, daytime dysfunction, and PSQI total score are provided as supplemental analyses.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Brain activation patterns revealed expected reward processing-related activation for age and sex. However, activation for sleep duration, dysfunction, and PSQI score did not correspond to those evident in previous total sleep deprivation studies.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Self-reported short sleep duration, perceived sleep-related dysfunction, and sleep quality via PSQI do not appear to be meaningfully associated with activation in well-described regions of the human neurobiological reward circuit. As these findings are counter to prior results using experimental sleep deprivation, future work focused on more direct comparisons between self-reported sleep variables and experimental sleep deprivation appears warranted.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/sleep\/zsz129","type":"journal-article","created":{"date-parts":[[2019,6,1]],"date-time":"2019-06-01T05:10:43Z","timestamp":1559365843000},"source":"Crossref","is-referenced-by-count":9,"title":["Neural reward processing in self-reported short sleepers: examination of gambling task brain activation in the Human Connectome Project database"],"prefix":"10.1093","volume":"42","author":[{"given":"Brian J","family":"Curtis","sequence":"first","affiliation":[{"name":"Department of Psychology, University of Utah, Salt Lake City, UT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula G","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Utah, Salt Lake City, UT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey S","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Radiology and Imaging Sciences, University of Utah, Salt Lake City, UT"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,5,31]]},"reference":[{"issue":"4","key":"2020083113221240600_CIT0001","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1016\/j.sleh.2015.10.004","article-title":"National Sleep Foundation\u2019s updated sleep duration recommendations: final report","volume":"1","author":"Hirshkowitz","year":"2015","journal-title":"Sleep Heal."},{"issue":"2","key":"2020083113221240600_CIT0002","doi-asserted-by":"crossref","first-page":"149","DOI":"10.1093\/sleep\/33.2.149","article-title":"The prevalence of short sleep duration by industry and occupation in the National Health Interview Survey","volume":"33","author":"Luckhaupt","year":"2010","journal-title":"Sleep."},{"key":"2020083113221240600_CIT0003","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1016\/j.neuroimage.2013.05.041","article-title":"The WU-Minn Human Connectome Project: an overview","volume":"80","author":"Van Essen","year":"2013","journal-title":"Neuroimage."},{"issue":"12","key":"2020083113221240600_CIT0004","doi-asserted-by":"crossref","first-page":"e00576","DOI":"10.1002\/brb3.576","article-title":"Sleep duration and resting fMRI functional connectivity: examination of short sleepers with and without perceived daytime dysfunction","volume":"6","author":"Curtis","year":"2016","journal-title":"Brain Behav."},{"issue":"4","key":"2020083113221240600_CIT0005","doi-asserted-by":"crossref","first-page":"239","DOI":"10.1016\/j.smrv.2009.08.001","article-title":"Pack AI.
