The vascular contribution to cognitive decline in ageing and dementia - Nature Reviews Neuroscience Growing evidence suggests that reduced cerebral blood flow contributes to cognitive decline in ageing and dementia. Attwell and colleagues discuss the underlying mechanisms and functional consequences...

Pathways to an Intergovernmental Panel on Pandemics: lessons from the IPCC and IPBES

Pandemics pose a global threat to human wellbeing, justice, economies, and ecosystems and are comparable with other planetary crises such as climate change and biodiversity loss in terms of urgency and impact. The global community would benefit from a dedicated scientific synthesis body to assess pandemic risks and solutions. In this Personal View, we explore proposals for an Intergovernmental Panel on Pandemics and assess potential pathways to its creation. Learning lessons from the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) might help national governments and international organisations to chart a course through important decisions about format, governance, operations, scientific scope and process, and ability to recommend policies that make the world safer.

🚨 Very, very big news. Today, a global coalition - including members of the IPCC, IPBES, and WHO expert advisors, as well as independent virologists, epidemiologists, and lawyers - started the process of creating an "IPCC for Pandemics."

What birds can teach us about the β€˜biological truth’ of sex Part of our job as educators is to give students a deeper understanding of the true diversity of sex and gender in the natural world.

ICYMI: In this essay for our series on sex differences in the brain, @nmbaran.bsky.social explains why it’s important for students to learn about the dynamic, complex process by which sexual differentiation occurs.

1/6 Why does the brain maintain such precise excitatory-inhibitory balance?
Our new preprint explores a provocative idea: Small, targeted deviations from this balance may serve a purpose: to encode local error signals for learning.

The history and future of resting-state functional magnetic resonance imaging - Nature This Review provides an overview of the history of resting-state functional MRI research, which has helped to reveal the spatiotemporal organization of the brain, and discusses how it can contribute f...

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

Confounds, and signals of interest in their own right!

Also interesting that resting state heavy hitters have been warning about physiological confounds since the 90s, and it’s still an issue (excerpt below from Dagli, Ingeholm, and Haxby 1999)
