AI trained with input from experts: scientists, clinicians and patients, very carefully and cautiously may solve problems instead of creating new ones. See our paper:

discussion will include "potential interventions (e.g., moving to one competition per year, restricting applications, capping resubmissions)." don't miss this

Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development. 🔗 www.biorxiv.org/content/10.6...

How it's going.

Our latest work looking at the neuroanatomical basis of impulsivity in youth is out now in Molecular Psychiatry!

New paper in PNAS! When the mind wanders, it often drifts to the body. We call this "body-wandering". These thoughts are often negative, but are associated with reduced ADHD & depression symptoms, driven by a distinct interoceptive-allostatic brain signature. pnas.org/doi/10.1073/pnas.2520822123

More evidence that the homeostatic pathway lamina 1 theory has no feet.

Is there a single "interoceptive sense"? Our new study in @commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪

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.
