Working memory limitations and dopamine modulation in probabilistic reasoning

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.

Distinct feedforward and feedback pathways for cell-type specific attention effects

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.

Intrinsic timescales in the visual cortex change with selective attention and reflect spatial connectivity

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

Sharp wave ripples in macaque V1 and V4 are modulated by top-down visual attention

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

Stimulus dependence of directed information exchange between cortical layers in macaque V1

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.

Top-down coordination of local cortical state during selective attention

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