Pleased to share our latest preprint examining the impact of glucodynamic variability on cognition. Hamish Deery shows that it is not the size of the energy budget per se, but the dynamic use of glucose & its coherence into metabolic networks that are important for cognition. #neuroskyence

Brain glucodynamic variability is an essential feature of the metabolism-cognition relationship https://www.biorxiv.org/content/10.1101/2025.04.30.651418v1

Congrats to Winnie Orchard & @sidchop.bsky.social on their new #ParentalBrain paper, now out in PNAS! They find evidence for the neuroprotective effect of parenthood for women AND men! 👩‍🍼👨‍🍼🧠 It's lovely work, and I'm proud to have played a tiny role in it. Read it here 👇 #neuroskyence #neuroimaging

Pleased to share our new #MetabolicConnectivity paper! We used #simultaneousPETMR to show that MC has ⬆️ utility for age & cognition prediction vs #fMRI FC. A bit surprising but it's more evidence of the utility of #fPET & MC as a measure of #BrainConnectivity 🧠⚛️ doi.org/10.1093/brai... #neuroskyence

Metabolic connectivity has greater predictive utility for age and cognition than functional connectivity

Deery et al. report that there is a reconfiguration of metabolic brain networks in ageing that is different to haemodynamic alterations and is more strongl

Our latest paper 'Reconfiguration of metabolic connectivity in ageing' is now out! We show that the brain's metabolic network declines in efficiency with age, and older adults use more of their energy budget to maintain this inefficient network. #neuroskyence doi.org/10.1038/s420...

Reconfiguration of metabolic connectivity in ageing - Communications Biology

Compared to younger adults, the metabolic connectome of older adults is characterised by a reduced capacity of hubs in frontal brain regions to connect to other regions, a higher metabolic cost and wo...
