The paper uses fMRI decoding to show that neural activity in the posterior putamen during learning predicts individual differences in habit versus goal-directed behavior across multiple cohorts.

This study attempts to replicate and extend findings on habit formation in humans using multi-modal MRI, but finds no clear habit formation with training duration and identifies goal-directed neural patterns instead.

The paper examines brain volumetric changes in a population before and after the COVID-19 outbreak and lockdown, finding increases in amygdala, putamen, and anterior temporal cortices, which diminished over time.

This study shows that counterconditioning after memory retrieval reduces the reinstatement of appetitive memories in humans.
