New paper in Imaging Neuroscience by Hecheng Jin, Ting Xu, et al:

Is Pearson’s correlation coefficient enough for functional connectivity in fMRI?

doi.org/10.1162/IMAG...

Yes, its a different world altogether

We can still do our work but let it be about the work and less about us? when we allow the self importance and big personality go, our work benefits.

“Vanity of vanities… all is vanity. You kill yourself to get to the grave. Especially you kill yourself to get to the grave before you die; and the name of the grave is ‘success’, the name of that grave is hullabullo boom boom horseshit.”

“There’s a popular view that connectivity, in the Facebook sense, is a good thing. In my world, it’s really bad. Dense connectivity is the killer. It is death.” — Karl Friston. hbarjournal.substack.com/p/karl-frist...

Very cool new work from the Iglesias group at MGH: A probabilistic histological atlas of the human brain for MRI segmentation (also available at OpenNeuro - openneuro.org/datasets/ds0...) : www.nature.com/articles/s41...

fun old experiment (1968): O. Lippold believed that the alpha rhythm was related to the physiological tremor in eye muscles (also ~10 Hz). so in this experiment, the eyeball was cooled & warmed to shift the muscle tremor frequency. when they measured EEG, the alpha frequency seems to change.

Be yourself! That's the only thing that has ever worked for me.

haha. no not going there with you. But people who have worked on the data, know. Dismissing empirical/experiential knowledge of people who have gone to hell & back to understand this is sheer hubris. I challenge you to also work on data for decades, study limitations and strengths, then conclude

Meh. take a crash course in complexity.

We recently wrote a paper on this topic, that was recently accepted but not yet out. Will love to hear your thoughts on it. Will share on my page soon.

A habit and working memory model as an alternative account of human reward-based learning Nature Human Behaviour - In this study, Collins proposes an alternative dual-process (working memory and habit) model of reinforcement learning in humans.

My paper is out!
Computational modeling of error patterns during reward-based learning show evidence that habit learning (value free!) supplements working memory in 7 human data sets.

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.

An enteric-DRG pathway for interoception and visceral pain in mice Wang et al. reveal a neuroanatomical and functional crosstalk between cholinergic enteric neurons and sensory neurons of the dorsal root ganglia that mediates colonic interoception. While this pathway...

Enteric neurons join the pain conversation! New paper shows that cholinergic circuits in the colon signals through DRG pathways, especially after inflammation. www.cell.com/neuron/fullt...

I woke up this morning thinking:
We. The. People.

That’s mighty nice.

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).

Can the motor system use sensory expectations to prepare for unexpected events?

Excited to share my latest work with @andpru.bsky.social – where we establish that sensory expectations shape neural population dynamics in motor circuits!

"these arrangements are not 'partnerships' or 'collaborations' but contracts that bring profit and publicity to AI firms, while making universities complicit in the continued empowerment of tech oligarchy and expansion of their 'AI Empire' (Tacheva and Ramasubramanian, 2023; Adams, 2024; Hao, 2025)"
