We examine neural circuits and neurochemical mechanisms that support learning and decision making

 

Main topic of research:

Learning and decision making

The topic of my research refers to the detailed understanding of brain operations that account for complex animal behaviour with focus on behavioural functions of the basal ganglia. The basal ganglia comprise several interconnected nuclei located in the forebrain. They interact with multiple regions of the cerebral cortex and play a major role in diverse functions ranging from movement control to cognition and motivation. The main purpose of our work is to delineate neuronal and neurochemical mechanisms of basal ganglia circuits and their role in goal-directed behaviour. In particular, we are interested in the involvement of basal ganglia and prefrontal cortex in learning and memory as well as decision making. Furthermore, we analyze basal ganglia dysfunctions in animal models of neurological and neuropsychiatric brain disorders. A number of neuroanatomical, neuropharma-cological, neurochemical and behavioural methods in rats are established to answer these questions.

 

During decision making metabolic activity is markedly enhanced in the prefrontal cortex. Magnetic resonance imaging (MRI) in combination with [18F]fluorodeoxyglucose positron emission tomography (PET) of the rat (from Endepols et al., 2010).
