This project aims to understand neural fundaments of extinction of appetitive conditioning in pigeons in a design that permits to analyze neural events governing acquisition, context dependent extinction and renewal along the full time frame (the 4th dimension). We combine single cell recordings, fMRI and optogenetic methods in awake pigeons to analyze key events as well as causal interactions between brain areas of the extinction network (NCL, NFL, arcopallium, hippocampus) at the cellular and at the overall systems level. By studying a different animal model we aim to discover variant as well as invariant properties of extinction learning in terms of behavior and neurobiology.
