(A) LC MRI contrast at the pre- and post-training timepoints for the Osc+ and Osc− conditions, for younger (top) and older (bottom) participants. (B) Associations between pre- to post-training change in LC contrast and training oscillatory power, a measure of how much participants increased their heart rate oscillations across practice sessions, for younger (top) and older (bottom) participants. Linear regression lines with 95% confidence intervals are shown in gray. Significance labels (*p < .05) refer to pairwise comparisons between pre- and post-training LC contrast.
