Sleep deprivation influences several critical functions, yet how it affects human brain white matter (WM) is not well understood. The aim of the present work was to investigate effect 32 hours sleep on WM microstructure compared changes observed in a normal sleep-wake cycle (SWC). To this end, we utilised diffusion weighted imaging (DWI) including tensor model, kurtosis and spherical mean technique, novel biophysical model. 46 healthy adults (23 deprived vs 23 with SWC) underwent DWI across...
Work by Flavell, Beach, and Chinsky indicated a change in the spontaneous production of overt verbalization behaviors when comparing young children (age 5) with older 10). Despite critical role that this evidence plays modern theories cognitive development working memory, there has been only one other published near replication work. In Registered Replication Report, we relied on researchers from 17 labs who contributed their results to larger more comprehensive sample children. We assessed...
Cortical microstructure is influenced by circadian rhythm and sleep deprivation, yet the precise underpinnings of these effects remain unclear. The ratio between T1-weighted T2-weighted magnetic resonance images (T1w/T2w ratio) has been linked to myelin levels dendrite density may offer novel insight into intracortical deprived brain. Here, we examined T1w/T2w in 41 healthy young adults (26 women) before after 32 h either deprivation (n = 18) or a normal sleep-wake cycle 23). Linear models...
A recent Registered Replication Report (RRR) of the development verbal rehearsal during serial recall revealed that children verbalized at younger ages than previously thought, but did not identify sources individual differences. Here, we use mediation analysis to reanalyze data from 934 ranging 5 10 years old RRR for purpose. From 7, time taken a child label pictures (i.e. isolated naming speed) predicted child's spontaneous labels visually presented reconstruction task, despite no need...

Abstract Cortical microstructure is influenced by circadian rhythm and sleep deprivation, yet the precise underpinnings of these effects remain unclear. The ratio between T 1 -weighted 2 magnetic resonance images (T w/T w ratio) has been linked to myelin levels dendrite density may offer novel insight into intracortical deprived brain. Here, we examined in 41 healthy young adults (26 women) before after 32 hours either deprivation ( n = 18) or a normal sleep-wake cycle 23). Linear models...
