🚨 Our latest preprint:

A new tool to provide assessments of experience of the built environment: the NDIX.

This has been now deployed in 4 studies, being written up.

Here is the methods preprint with a starcast of co-authors:
The NeuroDesign/NeuroArchitecture Index (NDIX): Development of a method to evaluate the impact of the built environment on health, cognitive performance, and wellbeing: https://osf.io/8369k
A huge thankyou to @alexaroblesgil.bsky.social for covering our research in the Marshall Islands for the @nytimes.com !

In the photo Ken Daniels (an expert indigenous sailor) is looking towards the horizon whilst wearing an fNIRS system.

Analysis underway!

Congrats to Ella for her new paper! She asked a really interesting question about how the brain represents uncertainty during hidden state inference, and in a lovely crossover with theoretical work, she shows that in mice, acetylcholine dynamics play a crucial role. www.biorxiv.org/content/10.1...
Acetylcholine reflects uncertainty during hidden state inference
To act adaptively, animals must infer features of the environment that cannot be observed directly, such as which option is currently rewarding, or which context they are in. These internal estimates,...

Moyamoya is a rare cerebrovascular disorder where arteries at the base of the brain narrow, blocking blood flow.
It can be devastating in children.
Lauren Harris, Charlotte Malcolm et al find metrics from neuroimaging help identify the neurocogntiive outcomes for these children:

New episode!! 🎙️🎉

A conversation w/ @erinhecht.bsky.social about the diversity and evolution of canine brains.

We've lived and worked with dogs for 15,000+ years, sculpting their brains and bodies along the way. What can we learn from their singular story?

Hidden Markov Models
Speaking of HMMs, really enjoyed this paper on dynamics underlying resting state and other conditions. The idea of a baseline state from which excursions lead to more integrated states is really interesting.

what happens when you spend two weeks learning new navigation or memory skills? as shown in our recent paper below, brain network connectivity changes but not hippocampal or other brain volumes! special thanks to collaborators Li Zheng and Steve Weisberg

Newly trained navigation and verbal memory skills in humans elicit changes in task-related networks but not brain structure

Now that we have Hidden Markov Models do we still need correlation matrices?? 😀
For example, this looks cool.

(I'm aware that HMMs are not new, I played with them in grad school...)

A study in Nature Neuroscience shows that the moments of failed attention we experience after sleep deprivation reflect brief ‘sleep-like’ episodes in the brain, corresponding to a brain- and body-wide event with altered brain activity, pupil size and brain fluid movement. #neuroskyence 🧪
