Juliane Martin: Foraging Decisions in Mice under Uncertainty
PhD defence, Friday 26 April 2019. Juliane Martin.
The search for food resources in the wild is termed foraging. These resources are often associated with uncertainty, as the animal cannot always know for sure where to find the most and best food. In the context of studying foraging decisions under uncertainty in the lab, variable interval schedules for reward delivery have been proven specifically useful. The optimal strategy to obtain as many rewards as possible under such schedules is called matching behavior. In her studies, Juliane addressed the underlying mechanisms of matching behavior. Her focus lied on how mice estimate and react to varying reward rates. To this end, she established a matching task in mice and carefully analyzed the observed choice behavior. Her results form the foundation for further comprehensive studies of how the brain makes decisions in the face of uncertainty.
The PhD degree was completed at the Danish Research Institute of Translational Neuroscience (DANDRITE), Science and Technology, Aarhus University.
