🚨 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:

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
Learning new navigation or memory skills engages flexible brain network dynamics without altering gray matter, white matter, or hippocampal 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 🧪

Sometimes it can be a pain choosing the route, and toughest when two paths seem equivalent.

Interesting article.

“The key take-home points are that if you take action for biodiversity in cities (through tree planting, or enhancing habitat in parks, or creating greenways) these actions will also likely yield benefits to human health.”
