Irrational choices via a curvilinear representational geometry for value

The paper shows that value is represented in a curved manifold in the vmPFC, leading to irrational decision-making when decoy options are worse in value.

Orthogonal but linked neural codes for value

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.

Tonic activity in lateral habenula neurons promotes disengagement from reward-seeking behavior

This study shows that tonic activity in lateral habenula neurons promotes disengagement from reward-seeking behavior, with no similar activity in VTA dopamine neurons.

Exploratory noise governs both flexibility and spontaneous errors and is regulated by cocaine

This study shows that exploratory noise influences both cognitive flexibility and spontaneous errors, with cocaine reducing exploration and improving performance by lowering lapse rates.

Neuronal responses support a role for orbitofrontal cortex in cognitive set reconfiguration

This study investigates neuronal activity in the orbitofrontal cortex (OFC) of rhesus macaques during cognitive set reconfiguration, identifying switch-related signals and match modulation patterns.
