Neural Circuits for Behavioral Adaptation

European Neuroscience Institute, Göttingen

Research

We uncover how peripheral signals from the body inform subcortical networks of the brain to modulate essential innate behaviors according to physiological needs and environmental opportunities.

We specialize in single-photon microendoscopy in the freely moving animal, as well as cell type-specific neural activity manipulations and neuropsychopharmacology to identify and characterize the neural substrates for behavioral regulation.
