If you're interested in computational psychiatry, come chat with me about the neurochemical markers of uncertainty processing at poster A10 #BAP2025

Exciting guest lecture by Angela Roberts on anhedonia and anxiety #BAP2025

We also looked at the above in relation to trait anxiety. Interestingly, both model-free and model-based results indicate that that high trait anxiety was associated with faster responses after the reversal (4/4)

We found that baseline glutamine+glutamate levels in the primary motor cortex M1 correlate with model-based prediction errors & volatility beliefs, suggesting a key neural marker for uncertainty processing (3/4)

To probe the underlying processes, we introduce a novel categorical state-transition extension of the Hierarchical Gaussian Filter (HGF) that tracks beliefs about stimulus transitions in a 4-choice probabilistic serial reaction time reversal learning task. (2/4)
