We study the integration of audiovisual information in cortical and subcortical networks in the rodent brain. We are especially interested in the interaction of task context and audiovisual integration.
In our research we make use of a combination of behavioral paradigms and large-scale extracellular neurophysiology with and without optogenetic manipulation. These techniques allow us to dissociate neural feedforward and feedback signals in cortical networks involved in audiovisual decision making.
We achieve this dissociation by posing different task constraints via cueing on the animal while keeping the physical stimuli identical across different contexts. This leads to a differential activation of the involved processing networks.
