This paper shows that stochastic decision policies can be optimal when considering the cost of control, using sequential sampling and recovering policies in macaques.

This study identifies neural encoding of the decisional reference point in macaques, showing that only the ventral bank of the anterior cingulate cortex encodes it at the population level.

This study introduces time-magnitude RL (TMRL), a new reinforcement learning framework, and shows that dopamine neurons encode a probabilistic map of future rewards in mice.

The paper investigates how early versus late noise affects context-dependent choice behavior in decision-making, showing opposing effects on choice accuracy.

This paper identifies a pathological elevation of the decisional reference point in depression patients, linking it to disease severity and proposing a virtual diagnostic test.

This study shows humans use divisive normalization in two different choice environments, suggesting it is a fixed cognitive mechanism.

This paper introduces a hybrid neural circuit model that combines normalized representation and winner-take-all dynamics through disinhibition, capturing decision-making behaviors and working memory.

The paper examines context-dependent choice in real-world settings using restaurant rating data, finding that valuations and choices are influenced by the context of available options.

This study shows that nonlinear reinforcement learning with divisive normalization introduces asymmetry in prediction error coding, explaining behavioral variability and supporting distributional RL theories.

The paper investigates inhibitory plasticity in mouse auditory cortex, finding that SST+ interneuron inputs show the most potentiation and contribute to decision accuracy under noise.

The paper models decision-making in a hierarchical neural network, showing how excitatory-inhibitory balance affects decision strategies under different uncertainty levels.

This study tests the Independence of Irrelevant Alternatives in C. elegans using olfactory chemotaxis assays, showing that neuronal constraints can lead to bounded rationality.
