🧠 New paper out in 𝘉𝘳𝘢𝘪𝘯
Why does tau pathology often begin in the entorhinal cortex in Alzheimer’s disease?
We show that brain-wide gradients of neuronal activity and amyloid-β may make this region particularly vulnerable to tau pathology.

In 1989, this video shook up neuroscience. Here, glutamate triggers waves of calcium movement between astrocytes, large brain cells that reach millions of neurons. A new wave of research is revealing how this behavior influences our brain states. quantamagazine.org/once-thou…

🧠 New preprint 🧠
We review models of brain activity and protein spread in neurodegeneration, and argue that linking them is key to understanding and intervention.

J.S. Bach’s music is timeless, and @DaniSBassett & @SumanSKulkarni are revealing why. Using network theory, they analyzed hundreds of Bach’s pieces. This approach could augment music therapy, production, and even Spotify recommendations. bit.ly/3WH0jCj

‼️🧠Neuronal activity causes symmetry breaking in neurodegenerative disease and pushes disease initiation🧠‼️
Happy to share a new paper with @AlainGoriely @BickMath 🥳

It has long been suspected that neuronal activity may promote early spreading of neurodegenerative diseases such as Alzheimer's.
In this paper with @cgAlexandersen and @BickMath, we show that this may indeed occur through a symmetry breaking bifurcation
