Chromatin has long been proposed to "store" memory related information; but what kind of information, contents or rules does it hold? Check out our new preprint: biorxiv.org/content/10.64898… 1/13

In total, we show how TD learning can be used as a comprehensive explanation of the effects of contingency on associative learning and discuss how this guides our future study of how the brain learns causality.

We thank the reviewers for their comments, who helped us refine our explanations of the various models and why they succeed or fail.

In total, TD errors improve over the ANCCR and Δ𝑃 definitions for measuring contingency. Moreover, contrary to claims from previous studies, dopamine responses can be comprehensively explained by TD learning models and primarily reflected prospective relationships. 10/n
