This study investigates how working memory limitations and dopamine modulation affect probabilistic decision-making in macaques, showing dopamine's role in adjusting working memory constraints.

The paper examines population coupling in V1 and V4 neurons of macaques, finding that choristers show stronger coupling to cortical state fluctuations than soloists, and attention modulates coupling strength.

This study investigates the effect of fluid control on the affective state of laboratory macaques and finds no significant impact on their psychological well-being.

This study examines how acute moderate alcohol consumption affects the speed of endogenous and exogenous attention shifts, finding that alcohol slows all types of attentional shifts equally.

The paper investigates how attention modulates neural responses in V1 and V4 by analyzing distinct feedforward and feedback pathways in macaque and mouse visual cortex.

This study examines how muscarinic receptor blockade affects attention shift speeds and learning improvements, showing increased shift times and reduced learning gains with scopolamine.

This paper introduces a neural geometry theory that explains visual perceptual learning by showing neural manifold shrinkage, rather than changes in tuning curves or noise correlations, is the primary mechanism.

The paper measures intrinsic timescales in the visual cortex during attention tasks and finds they change with attention and spatial connectivity.

This study shows dopamine modulates attentional processing in macaque parietal cortex by altering neuronal firing rates and gain variability.

This study shows that sharp-wave ripples occur in macaque visual areas during attentive states and affect reaction times to stimulus changes.

The paper investigates how stimulus size affects oscillatory activity and communication between cortical layers in macaque V1, revealing dynamic modulation of frequency bands for feed-forward and feedback signals.

This study maps visual information flow between cortical layers in macaque V1 and V4 and shows how attention modulates this communication.

The paper shows that local cortical state coordination during selective attention is retinotopically precise and progresses in a reverse hierarchical manner across brain areas.

This study examines how pupil-linked arousal modulates neural and behavioural signatures of perceptual evidence accumulation during decision-making.

The paper introduces PRIME-DE, an open resource for non-human primate MRI data, aggregating 13 datasets from 11 sites across 98 macaques.

This paper introduces a non-parametric test for detecting directed connectivity in multivariate autoregressive networks and applies it to multiunit activity data from monkeys.
