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.

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.

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?

The entire brain, more or less, is at work: ‘Language regions’ are artefacts of averaging
Models of the neurobiology of language suggest that a small number of anatomically fixed brain regions are responsible for language functioning. This derives from centuries of aphasia studies and deca...

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.

This looks awesome! The OSF link doesn't seem to be working at the moment though.

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.
