This study links dopamine receptor availability in specific brain regions to memory performance in older adults, identifying distinct dopaminergic circuits associated with different memory outcomes.

This paper introduces ELSI-Net, a deep learning method for automated Locus Coeruleus segmentation and feature extraction in aging and Alzheimer's Disease dementia, showing high agreement with manual ratings and correlations to CSF biomarkers.

This study evaluates the effects of phasic taVNS on pupil dilation in younger adults, finding that higher intensity and perceived stimulation lead to greater dilation, with intensity having a stronger effect than frequency.

This paper proposes spatial transformation and quality assessment methods for reliably imaging the small noradrenergic locus coeruleus using structural and functional MRI.

This study investigates learning across the human lifespan using a go/no-go task, showing age-related differences in reward and punishment sensitivity.
