Respiratory suppression enhances voluntary control of human action

The paper shows that breath holding during preparation improves voluntary movement, especially in tasks requiring suppression of reflexive actions, under high motivation.

Sustained visual signals in the primate cerebellar dentate nucleus drive associative learning

This study shows sustained visual signals in the primate cerebellar dentate nucleus are involved in visuomotor associative learning by enhancing discrimination of visual objects based on saccade direction.

Formation of brain-wide neural geometry during visual item recognition in monkeys

The paper shows that visual information propagates as a heterogeneous mixture of stochastic neural population signals across brain-wide regions in monkeys.

A method for evaluating hunger and thirst in monkeys by measuring blood ghrelin and osmolality levels

The paper measures blood ghrelin and osmolality in monkeys to assess hunger and thirst states under controlled food and water access conditions.

Distinct roles of the orbitofrontal cortex, ventral striatum, and dopamine neurons in counterfactual thinking of decision outcomes

This study identifies distinct roles of the orbitofrontal cortex, ventral striatum, and dopamine neurons in processing counterfactual outcomes during decision-making in monkeys.

Neuronal mechanism of the encoding of socially familiar faces in the striatum tail

The paper identifies a neuronal mechanism in the striatum tail that links social familiarity and object value, showing their shared encoding in face detection.

Noninvasive method for monitoring breathing patterns in monkeys

The paper develops a noninvasive method to monitor breathing patterns in monkeys by measuring nasal air temperature, showing it accurately reflects respiration and is unaffected by orofacial movements.

Comparison of neural population dynamics in the regression subspace between continuous and categorical task parameters

This study compares neural population dynamics for continuous and categorical task parameters using state-space analysis and optimal-stimulus paradigms in visual recognition tasks.

Dynamic prospect theory - two core economic decision theories coexist in the gambling behavior of monkeys

This paper combines prospect theory and reinforcement learning to model gambling behavior in monkeys, finding that probability weighting changes dynamically with reward prediction error.

Tonic firing mode of midbrain dopamine neurons continuously tracks reward values changing moment-by-moment

This study shows that dopamine neurons use a tonic firing mode to continuously track changing reward values in real time.

Amygdala controls saccade and gaze physically, motivationally, and socially

This study shows that the central amygdala (CeA) controls saccades and gaze direction based on emotional and social contexts through inactivation and optogenetic stimulation in monkeys.
