Research Project

Information processing in the brain can be influenced by emotional states, a phenomenon referred to as cognitive bias. A growing body of evidence suggests negative cognitive biases (“pessimism”) to be implicated in the aetiology of anxiety disorders and depression in humans. Mice lacking either one or both alleles of the serotonin transporter (5-HTT) gene constitute a commonly used rodent model for human anxiety disorders.
To assess the cognitive bias of 5-HTT deficient mice in comparison to wildtype controls, the aim of this project is to implement a translational, touchscreen-based cognitive bias test for this species. In a next step, the influence of early life experiences on the animals’ cognitive bias will be investigated. (SFB/TRR 58 “Fear, Anxiety, Anxiety Disorders”)
