A01 – Extinction Learning in the 4th Dimension

Onur Güntürkün, Roland Pusch

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.

Guiding questions of A01:

  • Does extinction learning change the neural representation of conditioned stimuli (CS) in the “prefrontal” NCL, the motor  arcopallium, the visual NFL, and the hippocampus in context-specific ways?
  • How is the CS-representation in visual NFL and the hippocampus modulated by the the “prefrontal”  NCL during extinction learning and renewal?
  • Which forebrain areas beyond these four structures participate in appetitive extinction and renewal and what is their sequence of activation during a discrimination-extinction-renewal-cycle?
