Neural Mechanisms Linking Perception and Action

Research Summary

Our lab is interested in neural mechanisms underlying higher-order brain functions linking perception and action, especially decision-making. We are addressing the question how the brain processes sensory information and combines it with other information in order to select what action to take next and when to take that action. These mechanisms have mainly been studied from a psychological point of view, whereas neurophysiologists have largely concentrated on lower-level mechanisms. We are bridging this gap by utilizing both behavioral and neurophysiological methods and by using mathematical models for exploring potential neural mechanisms. The goal of our research is to provide a solid foundation for understanding human choice behavior, the neural implementation of decision mechanisms, as well as problems with decision-making in neurological and psychiatric disorders.

In addition, our lab is also active in the area of neuroengineering, developing new technology that allows neuroscientists to address questions or test hypotheses that are difficult or impossible to investigate with currently available techniques.
