Autonomic physiological coupling of the global fMRI signal - Nature Neuroscience The brain and body are necessarily connected. Here the authors show that brain blood flow and electrical activity are coupled with systemic physiological changes in the body.

This may be relevant? www.nature.com/articles/s41...

Data only shows associations. Turning those into claims about mechanism or causation? That requires a Rosetta Stone of prior knowledge + theory. Resting-state fMRI is purely observational; correlation is its currency. From this, plenty of "theoretical toys" about brain function can be built...

Predictive Modelling of Depression Treatment Response using Individual Symptoms and Latent Factors Machine learning models have increasingly been used to identify predictors of treatment response in depression, and it is hoped that they may eventually help with clinical decision making. However, th...

Agreed! I'm often excited about cool, emerging fMRI methods which promise a lot. I've preregistered their use with high hopes and things fall flat. Post-hoc, the old methods turn out more sensitive. Obviously there are lots of factors, but it's made me quite hesitant without repeated validation.

Altered basal forebrain regulation of intrinsic brain networks in depressive and anxiety disorders - Nature Mental Health Using 7T resting-state functional MRI data, the authors investigate the effective connectivity of basal forebrain areas in a transdiagnostic sample of patients with anxiety and depression and healthy ...

Launched in 2023, Imaging Neuroscience is now firmly established, with full indexing (PubMed, etc.) and 700 papers to date.

We're very happy to announce that we are able to reduce the APC to $1400.

Huge thanks to all authors, reviewers, editorial team+board, and MIT Press.

We had two preprints approved in August (these were submitted in May & July). However, since approval, the web pages are no longer available (e.g., osf.io/byu7f_v1). Is this expected?

We show how aging reshapes the brain’s language and memory networks, revealing striking shifts in hemispheric specialization across the lifespan.

Would advise against wrist-worn wearables for heart rate, they're VERY prone to noise. Ideally ECG, but even finger pulseox would be superior. Done this stuff a lot with movies and am happy to chat more.

"To make a meaningful contribution to #neuroscience, #fMRI must break out of its silo."

Is interoceptive sensing unified across internal organs? πŸ«€πŸ« Our high-powered psychophysical study (N=241) suggests not. Bayesian evidence indicates interoceptive processes are largely modality-specificβ€”challenging the idea of a unitary interoceptive sense.

My impression is that this is especially problematic in the psychological therapy world, both public and private spheres. Many new therapies are just rebranded CBT but require a $15k training fee to be licensed.

My 3 fave ways to use: 1) optimizing my code that's already written; 2) going back and forth to understand stats concepts; and 3) mundane formatting stuff on office (e.g., I got it to write code to accept track changes in word and then underline said for a revision)
