🔊NEW RESEARCH: The chemical histamine – widely associated with the body's allergy response – shapes how the brain forms memories and handles negative experiences, according to a new study. Researchers found that raised histamine levels facilitated communication within the brain's memory networks.

Very happy to share this work on a preprint! Coauthored with @mikebrowning.bsky.social @Erdem Pulcu @lhuntneuro.bsky.social www.biorxiv.org/content/10.6... How do we learn when rewards and punishments change independently—and how does this go awry in anxiety and depression?
Valence-specific representation of uncertainty in the anterior cingulate is impaired in those with affective symptoms
The ability to seek reward and avoid punishment is a fundamental survival instinct. In natural environments, however, the statistics of rewards and punishments can change independently of one another....

Really interesting, brief ideas paper. Clearly relevant to treatment research-- the mechanism by which you leave an illness state is unlikely to just be the opposite of the mechanism by which you entered it (can see how this might apply to e.g. SSRIs in depression).

New preprint alert with @mikebrowning.bsky.social and Chamith Halahakoon! People have been using computer-based reinforcement learning tasks with affect probes. But to what extent do they reflect real-life affective experience? We tested this with 3 weeks of EMA + RL tasks in 339 participants.
Pramipexole vs. quetiapine vs. amantadine in TRD. Interesting open label, short term RCT using a surprisingly low dose (I suspect that the reported dose of 37.5mg of pramipexole is a typo and it should be 0.375mg) www.sciencedirect.com/science/arti...
