The paper identifies simplex-shaped neural manifolds for number representation in the human medial temporal lobe and finds similarities with large language models.

The paper investigates how bilinguals represent semantic concepts in two languages, finding shared neural geometries that support translation despite language-specific neuron responses.

The paper proposes a computational framework for zero-shot control in dynamic pursuit tasks and demonstrates its implementation in a graph convolutional network, showing transferability and change-of-mind behavior, supported by neural recordings.

This study investigates how the anterior cingulate cortex integrates experiential and observational evidence in a two-player game, revealing neural mechanisms for dynamic belief updating.

This study investigates how the brain generalizes emotions across individuals, finding that the insula encodes emotions and persons separately, enabling cross-person generalization.

This study investigates how representational geometry of visual working memory changes between encoding and maintenance phases using human fMRI.

The paper shows that selective observation biases social inference through hysteresis-like effects in human decision-making during competitive interactions.

The paper examines brain activity during a continuous prey-pursuit task, identifying distinct roles for hippocampus, ACC, and OFC in decision-making processes.

The paper investigates how hippocampal neurons track multiple agents during pursuit tasks, finding multiplexed neural maps and semi-orthogonal subspaces for distinguishing agents.

The paper uses a control theoretic approach to analyze neural activity in macaques during a continuous pursuit task, revealing how latent control variables influence decision-making and change of mind.

The paper shows that different learning strategies in foraging lead to distinct reactivation patterns in specific brain regions.

This study shows that activating hypothalamic GABAergic neurons in macaques increases naturalistic eating behavior and food motivation, with specific effects on palatable food.

The paper examines neural coding for value in six brain regions and finds no explicit value neurons, but shows value is encoded implicitly through orthogonal yet linked population subspaces.

The paper investigates how the brain binds features of options during decision-making using aligned and orthogonal subspaces in neural activity.

This study shows that the dorsal anterior cingulate cortex (dACC) in macaques encodes both world-centric and avatar-centric variables during pursuit and evasion tasks.

This study examines how neurons in reward regions of macaques encode safe and risky offers during a gambling task, finding distinct response subspaces for each type of offer.

OpenMonkeyStudio provides a deep learning-based system for markerless 3D pose estimation in freely moving macaques, enabling automatic tracking and action recognition in unconstrained environments.

Monkeys predict future prey positions during pursuit, and dACC neurons encode these predictions.

This study compares non-human primate and deep reinforcement learning agent performance in a virtual pursuit-avoidance task, finding agents primarily learn first-order physics while the primate exhibits second-order physics.

The paper examines macaque pupil responses to offered and anticipated rewards, finding opposing correlations that challenge the simulation hypothesis and suggest an accept-reject model of comparison.
