AI is growing exponentially at a timescale of months while the economy is growing at a timescale of decades. How should we model the economy with rapidly increasing intelligence tech and slowly increasing physical tech? New AI+econ paper.

Heart rate variability (HRV) is one of the widely used physiological measures in psychophysiological research. But with over 100 indices to choose from, how do we know which ones to use?
In our latest paper, we take a data-driven approach to help answer this.

Can machine learning really beat classic stats at classifying chronic pain?
Excited to share the first in our series of papers using hypothesis-driven analyses to identify reproducible, verifiable biomarkers of chronic pain. We validated findings across three cohorts (N=197).

Sunavsky et al. find that chronic low back pain is associated with hyperconnectivity between the nucleus accumbens and prefrontal cortex regions, a pattern that predicts pain intensity and was partly reproduced between different study cohorts #PAIN bit.ly/4neD5zr

It's been a while since our last laminar MEG paper, but we're back! This time we push beyond deep versus superficial distinctions and go whole hog. Check it out- lots more exciting stuff to come! 🧠📈
🚨🚨🚨PREPRINT ALERT🚨🚨🚨
Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!

When you successfully anticipate future events, what happens to your ability to encode the present? 🤔
Successful prediction increases the likelihood of successful encoding. We speculate about how switching between distinct encoding & prediction states can produce this effect.
