Very nice and interesting work on how to achieve accurate estimates in inhibitory control tasks.
Excited to announce that our paper (led by @hyejinjad & Derek Smith) is out in Nature Human Behavior: go.illinois.edu/Lee2025_NHB We use 36 days of testing in 4 inhibitory control tasks to examine the precision of inhibitory control measures in *individuals* and how they vary 🧵👇
Very happy to have been a small part of this 👇
Very excited to share our new preprint! In this paper, we analyzed weeklong actigraphy data from 77K UK Biobank participants and found robust Age- and Sex-Related Differences in Sleep Patterns and Their Relations to Self-Reported Sleep and Mood biorxiv.org/content/10.110… #sleep…
Very nice in @pnas - people who slept closer to their own culture's norms for sleep duration had better overall health. Sleep duration is more complex than often considered in a strict neuroscientific or biomedical sense. @ChristineOuBC @StevenHeine4 pnas.org/doi/10.1073/pn…
Very interesting from @VidalDidac - MUCH higher reliability for structural neuroimaging measures with longer follow-up time rather than more follow-ups or higher n. 2.-year follow-up requires 4 times higher n than 6-year follow up. @LCBC_UiO direct.mit.edu/imag/article/d…
Did you know that different prenatal environment causes MZ twins' brains to deviate? But when exposed to cognitive intervention in adulthood, common genetics make their brains converge while DZ twin brains become more different. Fascinating! @LCBC_UiO biorxiv.org/content/10.110…

Preprint from @VidalDidac - a common brain factor underlying memory decline in older age. Stronger associations in older, but independent of genetic Alzheimer risk. Very interesting work using >10.000 MRI scan. @LCBC_UiO biorxiv.org/content/10.110…

We find hippocampal correlates of superior episodic memory are the same across adulthood - we don't find evidence that special hippocampal features are important in aging across memory activity, macrostructure, microstructure and atrophy. @LCBC_UiO rdcu.be/edvSC

This is the coolest preprint I have been a (small) part of: twins cybercycling in virtual reality to demonstrate how early and later environmental influences on the cortex can be distinguished and modified @LCBC_UiO @KWalhovd biorxiv.org/content/10.110…

Really interesting preprint from @max12elliott et al: 1-year brain changes reliably detected by cluster-scanning - burst of multiple, very short T1's. Great potential for tracking individual differences in brain change over clinically meaningful intervals. medrxiv.org/content/10.110…

New paper: neural segregation in development & dedifferentiation in aging associate with memory. Within & between-network FC during encoding and retrieval, 2 samples, 7-82 years, n=734, using a multiverse approach. Lead by Håkon Grydeland 👏 @LCBC_UiO sciencedirect.com/science/articl…
Great opportunity 👇
Two open positions (Lund University): - Postdoctoral fellow at the Department of diagnostic radiology (deadline Feb 24). - Associate Senior Lecturer in Medical Radiation Physics (deadline Feb 25). shorturl.at/VtCVC
Enjoyable read in @Brain1878 by @tompollak against "inflammatory reductionism" in psychiatry, and in favour of ‘tolerance of ambiguity’ - the extent to which an individual can cope without certainty. academic.oup.com/brain/article/…
Review: 85% of 27.5k participants rated sleep as important/ very important for brain health. But the evidence for a causal role of sleep is surprisingly weak relative to the amount of attention to sleep in science and society. @KWalhovd @LCBC_UiO journals.sagepub.com/doi/10.1177/10…
