Serial attentional resource allocation during parallel feature value tracking

This study investigates the precision of tracking two changing color streams and finds imbalanced tracking precision and time-varying attentional allocation between them.

Seeing and Extrapolating motion trajectories share common informative activation patterns in primary visual cortex

This study shows that motion direction during occlusion can be predicted from activity patterns in low-level visual areas during visible motion, suggesting shared computational circuits in primary visual cortex.

Attention expedites target selection by prioritizing the neural processing of distractor features

The paper shows that prioritized processing of distractor colors speeds up target identification by enhancing neural gain and then attenuating distractors.

A comprehensive score reflecting memory-related fMRI activations and deactivations as potential biomarker for neurocognitive aging

The paper introduces and validates a comprehensive fMRI score, FADE-SAME, to quantify memory-related neural activity changes associated with neurocognitive aging.
