Very excited to see this work from Eyiyemis Damisah's group at Yale out in @natneuro.nature.com www.nature.com/articles/s41... They combined our gamified aversive learning task (www.nature.com/articles/s41...) with single unit recordings to show that claustrum neurons encode uncertainty

Human claustrum neurons encode uncertainty and prediction errors during aversive learning - Nature Neuroscience
Human claustrum neurons track uncertainty and prediction errors during aversive learning, suggesting a role for the claustrum in updating beliefs and guiding adaptive behavior in dynamic environments.

Impaired Goal-Directed Planning in Transdiagnostic Compulsivity Is Explained by Uncertainty About Learned Task Structure
Diminished use of goal-directed (model-based) decision making is a hallmark of transdiagnostic compulsivity, promoting an overreliance on inflexible and habitual behaviors. However, the origin of this...

Finally out!! This paper comes from my undergrad work and marks my very first fMRI project. Here we use mouse tracking and fMRI to show how repeated moral decisions are shaped by the trade-off between reward and consistency, and how the brain adapts to this conflict over time.
