'Robust circular cluster-based statistics
for respiration-brain coupling'

New preprint, and what a way to welcome @teresaberther.bsky.social to the #neuroskyence community. With @eliobalestrieri.bsky.social, she developed CBPT for circular #bodybrain analyses.

Fleming and colleagues show that poorer glucose control is linked to greater reliance on recent rewards during learning, which subsequently linked to higher depression symptoms, identifying a potential pathways linking metabolic health to mental health.

Two new preprints on multilevel HMMs! Time series data is now pervasive in psychology and new methods are needed to model the dynamics in such data. Hidden Markov Models (HHMs) are powerful models for dynamics in which a system is switching between a number of discrete states.
