The paper maps human hippocampal perfusion and microvascular pulsatility across age using MRI and integrates these with histological and transcriptomic data, revealing distinct spatial organization and age-related differences.

The paper introduces CCSI, a metric linking cortical blood flow and cellular architecture, showing its correlation with metabolic and structural features across brain regions.

This study finds that older adults show tonic hyperactivity in the locus coeruleus-noradrenaline system, as evidenced by weaker behavioral, pupillometric, and EEG responses to arousal.

This study shows that arousal increases locus coeruleus blood flow and modulates brain responses to negative-valence stimuli, while the amygdala shows valence-general responses.

This study compares the reliability of oculomotor capture and fixation times in measuring learning-dependent distractor suppression across three datasets, finding oculomotor capture to be more reliable and showing higher reliability in older adults.

This study examines how arousal affects attentional priority and processing speed in young and older adults using eye movements, finding no arousal effect on priority in older adults but increased pupil size and decreased evoked responses.
