Caffeine is frequently used to combat sleepiness and impaired performance caused byinsufficient sleep. It is unclear (1) whether daily use of caffeine could prevent or exacerbate the GMalterations induced by 5‑day sleep restriction (i.e. chronic sleep restriction, CSR), and (2) whether thepotential impact on GM plasticity depends on individual differences in the availability of adenosinereceptors, which are involved in mediating effects of caffeine on sleep and waking function. Thirty‑six healthy adults participated in this double‑blind, randomized, controlled study (age = 28.9 ± 5.2 y/;F:M = 15:21; habitual level of caffeine intake < 450 mg; 29 homozygous C/C allele carriers of rs5751876of ADORA2A, an A 2A adenosine receptor gene variant). Each participant underwent a 9‑day laboratoryvisit consisting of one adaptation day, 2 baseline days (BL), 5‑day sleep restriction (5 h time‑in‑bed),and a recovery day (REC) after an 8‑h sleep opportunity. Nineteen participants received 300 mgcaffeine in coffee through the 5 days of CSR (CAFF group), while 17 matched participants receiveddecaffeinated coffee (DECAF group). We examined GM changes on the 2nd BL Day, 5th CSR Day,and REC Day using magnetic resonance imaging and voxel‑based morphometry. Moreover, we usedpositron emission tomography with [ 18 F]‑CPFPX to quantify the baseline availability of A 1 adenosinereceptors (A 1 R) and its relation to the GM plasticity. The results from the voxel‑wise multimodalwhole‑brain analysis on the Jacobian‑modulated T1‑weighted images controlled for variances of cerebral blood flow indicated a significant interaction effect between caffeine and CSR in four brainregions: (a) right temporal‑occipital region, (b) right dorsomedial prefrontal cortex (DmPFC), (c)left dorsolateral prefrontal cortex (DLPFC), and (d) right thalamus. The post‑hoc analyses on the signalintensity of these GM clusters indicated that, compared to BL, GM on the CSR day was increasedin the DECAF group in all clusters but decreased in the thalamus, DmPFC, and DLPFC in the CAFFgroup. Furthermore, lower baseline subcortical A 1 R availability predicted a larger GM reduction in theCAFF group after CSR of all brain regions except for the thalamus. In conclusion, our data suggest anadaptive GM upregulation after 5‑day CSR, while concomitant use of caffeine instead leads to a GMreduction. The lack of consistent association with individual A 1 R availability may suggest that CSR andcaffeine affect thalamic GM plasticity predominantly by a different mechanism. Future studies on therole of adenosine A 2A receptors in CSR‑induced GM plasticity are warranted. 001030414 536__ $$0G:(DE-HGF)POF4-5253$$a5253 - Neuroimaging (POF4-525)$$cPOF4-525$$fPOF IV$$x0 001030414 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001030414 7001_ $$0P:(DE-Juel1)165827$$aLange, Denise$$b1 001030414 7001_ $$0P:(DE-HGF)0$$aBaur, Diego Manuel$$b2 001030414 7001_ $$0P:(DE-Juel1)179271$$aFoerges, Anna$$b3 001030414 7001_ $$0P:(DE-Juel1)180306$$aChu, Congying$$b4 001030414 7001_ $$0P:(DE-Juel1)174035$$aLi, Changhong$$b5 001030414 7001_ $$0P:(DE-HGF)0$$aElmenhorst, Eva-Maria$$b6 001030414 7001_ $$0P:(DE-Juel1)166419$$aNeumaier, Bernd$$b7 001030414 7001_ $$0P:(DE-Juel1)131672$$aBauer, Andreas$$b8 001030414 7001_ $$0P:(DE-HGF)0$$aAeschbach, Daniel$$b9 001030414 7001_ $$0P:(DE-HGF)0$$aLandolt, Hans-Peter$$b10 001030414 7001_ $$0P:(DE-Juel1)131679$$aElmenhorst, David$$b11$$eCorresponding author 001030414 773__ $$0PERI:(DE-600)2615211-3$$a10.1038/s41598-024-61421-8$$gVol. 14, no. 1, p. 12724$$n1$$p12724$$tScientific reports$$v14$$x2045-2322$$y2024 001030414 8564_ $$uhttps://juser.fz-juelich.de/record/1030414/files/s41598-024-61421-8.pdf$$yOpenAccess 001030414 8564_ $$uhttps://juser.fz-juelich.de/record/1030414/files/s41598-024-61421-8.gif?subformat=icon$$xicon$$yOpenAccess 001030414 8564_ $$uhttps://juser.fz-juelich.de/record/1030414/files/s41598-024-61421-8.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 001030414 8564_ $$uhttps://juser.fz-juelich.de/record/1030414/files/s41598-024-61421-8.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 001030414 8564_ $$uhttps://juser.fz-juelich.de/record/1030414/files/s41598-024-61421-8.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 001030414 909CO $$ooai:juser.fz-juelich.de:1030414$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 001030414 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)179271$$aForschungszentrum Jülich$$b3$$kFZJ 001030414 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166419$$aForschungszentrum Jülich$$b7$$kFZJ 001030414 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131672$$aForschungszentrum Jülich$$b8$$kFZJ 001030414 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131679$$aForschungszentrum Jülich$$b11$$kFZJ 001030414 9131_ $$0G:(DE-HGF)POF4-525$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5253$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vDecoding Brain Organization and Dysfunction$$x0 001030414 9141_ $$y2024 001030414 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001030414 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2023-08-24 001030414 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2023-08-24 001030414 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2023-08-24 001030414 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2023-08-24 001030414 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001030414 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2023-08-24 001030414 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bSCI REP-UK : 2022$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-07-29T15:28:26Z 001030414 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-07-29T15:28:26Z 001030414 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Anonymous peer review$$d2024-07-29T15:28:26Z 001030414 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)1040$$2StatID$$aDBCoverage$$bZoological Record$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-18 001030414 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2024-12-18 001030414 920__ $$lyes 001030414 9201_ $$0I:(DE-Juel1)INM-5-20090406$$kINM-5$$lNuklearchemie$$x0 001030414 9201_ $$0I:(DE-Juel1)INM-2-20090406$$kINM-2$$lMolekulare Organisation des Gehirns$$x1 001030414 980__ $$ajournal 001030414 980__ $$aVDB 001030414 980__ $$aUNRESTRICTED 001030414 980__ $$aI:(DE-Juel1)INM-5-20090406 001030414 980__ $$aI:(DE-Juel1)INM-2-20090406 001030414 9801_ $$aFullTexts
