Updated on the 🧠#brain effective connectivity library.
1. Added #Reservoircomputing causality as nonlinear #Granger:
github.com/alecrimi/eff...
2. Now labels on to the nodes
3. Added directionality shown with colors from blue to white (white as the arrows)

Chalks and Bronzes. Hendrik Andersen was a Norwegian #Sculptor who after living in US and France moved stably in #Rome, where he had a house (one room studio, one room museum, and the rest for living), at his death he donated the house with everything in it to the city of Rome.

3/3 The takeaway: Tackling poverty isn’t enough — policies that reduce structural inequality itself (taxation, social safety nets, school equity) could help protect children’s brains and future mental health. 🌍🧠

Macroeconomic income inequality, brain structure and function, and mental health - Nature Mental Health

Rakesh et al. used data from the Adolescent Brain Cognitive Development cohort study to evaluate the relationship between state-level income inequality, brain structure and function, and mental health in young people.

2/3 These brain differences partly mediate the link between inequality and later mental health problems (like anxiety & depression). In other words, inequality leaves a biological footprint, changing neurodevelopment in ways that affect well-being.

1/3 🧠"#Macroeconomic income inequality, brain structure & function, and mental health." Income inequality doesn’t just shape society — it shapes the brain. Children growing up in more unequal U.S. states had thinner cortex, smaller surface area, and altered #brain connectivity

Amazing paper:"Arousal as a universal embedding for spatiotemporal brain dynamics"🧠🐁 𒅒𒈔
www.nature.com/articles/s41... you can even find the #autoencoder based code: github.com/ryraut/arous...
but dear #Brain people🧠,
why do you find cool brain dynamics, state trajectories, embedding?

#OpenSource #Robotic Hand That Costs Just $300. @TetherIA_ai officially launched its robotic hand:
- 314 USD
-CAD, electronics, and firmware are all open source
-7 Active Degrees of Freedom (16 joints) with a tendon-driven design
-400 grams
dear #biologists someone can pipette for you

Li #attractor=chaotic vibes like Lorenz/Chen use its wild dynamics for #ReservoirComputing to process time series.
The truth: just use it because it looks cool⚔🏴‍☠️🌊
def dequan_li(x,y,z):
dx = a*(y - x) + y*z
dy = b*x - x*z+y
dz = c*z + x*y/3
return dx,dy,dz

Spiking #Brain, a new bio-inspired #LLM doing everything more efficiently, faster, with less data:
- 100x TTFT on 4M token inputs
- 97% energy savings
The scariest part of this is that they don't use #Nvidia but those alternative Chinese Metax #GPUs

Thoughts? @ceciletamura.bsky.social 👇
