Scientists have devised a novel framework to compare and analyze stochastic oscillations, the random rhythms that pervade life. These oscillations, from fireflies to heartbeats, have different underlying mechanisms and implications. The new approach could help understand and manipulate oscillators that affect health, such as brain waves and cardiac rhythms. neurosciencenews.com/life-osci

I'm still amazed by this every time. Watch the transient dynamics (relatively synchronous dampening ) of autotroph biomass in a 5-patch turn into an oscillatory pattern with completely asynchronous dynamics. in
AND I'M DOING ACTUAL RESEARCH WITH THIS CAN YOU BELIEVE IT THIS IS SO COOL

“respiration drives gamma oscillations in the piriform cortex, which correlate with local feedback inhibition… [oscillations] locally segregate neuronal assemblies through a winner-take-all computation leading to sparse odor coding during each breathing cycle.”

The Empirical Mode Decomposition (EMD; emd.readthedocs.io/en/stable/) python package just passed 100,000* pip downloads!!

Seems like only yesterday I was amazed it passed 20k...

Thanks if you've taken a look!

I got to visit Aarhus University in Denmark yesterday to give a talk and discuss my research at the Center for . My first time visiting an institute for a talk since COVID. I presented research on how to adjust our strategies of us AI to explain rather than predict neural activity in musical sewuences. Mapping oscillators to Bayesian models in temporal prediction and how predictions play an important role in audiograms.

I got to have long discussions ranging from the purpose of mental illness in music development, the feeling of groove in parkinson's and cross frequency coupling in interpersonal synchronization. Very nice to be at a center dedicated to music neuroscience and see all the varied ways it can be studied.

And at the end I got to catch the last days of the Groove Workshop, seeing really good talks by @joncannon_neuro, Ed Large and Benjamin Morillon over a pizza and beer.

Thanks to Peter Keller for the invitation and an amazing day! I hope I get invited again soon!

Fourier analysis uses sinusoids as basis function. I have seen this argument sometimes (explicit and implicit): given that for brain data Fourier analysis returns non-zero coefficients across all frequency bins, this means that there are lots of oscillators in the brain (1 per examined frequency).

I thought of following demo to illustrate the aspect that jumping from a measure directly to physiology is tricky: instead of sinusoids, use triangular functions 🔺 to represent the signal. It's definitely possible to reconstruct signals that way, achieving a good to fantastic fit (can make the signal + reconstruction curves indistinguishable by just piling on more terms).

Does that mean that there are lots of triangular oscillators in the brain? I would say no. 🙃

This project has been a major part of my academic life since 2016....

New Therapeutics in Alzheimer’s Disease Longitudinal Cohort study (NTAD)

Repeated measures data from participants with disease/#MCI + controls

An absolutely heroic amount of work from a big team - recruitment is closed, baseline data collection is complete and now the protocol paper is out!

Looking forward to research coming next year..
