Research and ongoing projects

In the Jacob lab, we study complex cognitive functions at the level of individual neurons and their networks. Intelligent, goal-directed behavior is produced by the interaction of populations of neurons in the cognitive brain centers such as the prefrontal cortex, the parietal cortex and the basal ganglia. We are particularly interested in how we learn and memorize behaviorally relevant information on multiple time scales, how this information is transformed into purposeful actions, and how neuromodulators such as dopamine regulate the underlying circuits.

We investigate cognitive mechanisms in animal models and in humans. To study specific brain functions, we design and train controlled behavioral tasks. We then combine multiple state-of-the-art techniques in mice, including large-scale extracellular recordings, optogenetic manipulation of defined cell types and networks, fluorescent imaging and computational analysis and modelling. In a unique interdisciplinary approach, we develop and use technologies for recording from populations of individual neurons in human neurosurgical patients. This translational line of research allows us to work towards a deep understanding of the principles of high-level cognitive functioning. Cognitive functions are impaired in many neurological and psychiatric disorders. Little is known about the neuronal mechanisms. Our long-term goal is to contribute to a better understanding of the cellular basis of mental health and disease.
