Effects of Stress and Genotype on Meta-parameter Dynamics in Reinforcement Learning

Neural Information Processing Systems

Stress and genetic background regulate different aspects of behavioral learning through the action of stress hormones and neuromodulators. They are hypothesized to be related to neuromodulatory levels in the brain. We found that many aspects of animal learning and performance can be described by simple RL models using dynamic control of the meta-parameters. To study the effects of stress and genotype, we carried out 5-hole-box light condition- ing and Morris water maze experiments with C57BL/6 and DBA/2 mouse strains. The animals were exposed to different kinds of stress to evaluate its effects on immediate performance as well as on long-term memory.
