how does his brain do it ? #neuroscience #memory #sport Nelson Dellis 6x US memory champion YouTube video by Roselyne Chauvin

The 6x US memory champion – Nelson Dellis – can memorize a deck of cards in 40 seconds and knows the first 10K digits of pi.
To figure out how, he let us peak inside his brain. Here is what we learned in our precision brain mapping study www.biorxiv.org/content/10.6...

Cascades and convergence: Dynamic signal flow in a synapse-level brain network Author summary To understand how the brain processes and merges information from our senses, we need more than just a “wiring map” of its connections; we need to see how signals actually travel throug...

🚨Another new one from the lab!

Cascades and convergence: Dynamic signal flow in a synapse-level brain network

We simulate sensory cascades in a bona fide biological neural network.

I couldn't find a tool to plot different #neuroimaging data in one consistent style, so I made one! Meet yabplot (yet another brain plot) - a #Python package for (sub)cortex & tracts.🧠
- Simple API
- Built-in atlases
- Custom atlas support

We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, “Two Axes of White Matter Development”, is now out in @natcomms.nature.com! 🛣️🧠✨

The revised version of our paper on the impact of top-down feedback is now out @elife.bsky.social:

doi.org/10.7554/eLif...

tl;dr: we show that using human-brain-like feedback/anatomy in a deep RNN leads to human-like visual biases!

Computer model predicts aspects of cognitive performance The Allen Human Brain Atlas helped researchers design a model that looked at “intrinsic neural timescales”

Intelligence is not just about having "strong" brain connections. It’s also about how efficiently the brain coordinates processing speed across regions.

@lindenmp.bsky.social and @jason-z-kim.bsky.social share what their computer model is revealing about cognitive power: https://bit.ly/3LQuoxT

Now in press one of my last PhD projects! We traced the neurobiological profile of fMRI BOLD signal variability, a measure that has been related to age, behaviour, disease status, but had not yet been fully contextualised within the brain's multiscale architecture. www.nature.com/articles/s41...

Nine subcortical/cerebellar atlases included in the subcortex_visualization Python package (and subcortexVisualizationR package in R). The atlases are depicted in two-dimensional vector graphic format.

The extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️
