Research Theme
Synapses, Circuits and Behaviour
Research
Our aim is to reveal how neuronal networks integrate sensory information in a way that is relevant for the animal’s behaviour. We are using the mouse primary visual cortex as a model system of cortical integration of sensory and non-sensory information. Neurons in the primary visual cortex respond to specific features of visual stimuli such as their location, their orientation and their direction of movement. These visual responses do not only depend on the characteristics of the stimuli but are also strongly modulated by the context in which they are perceived, such as the animal’s behavioural state and its previous experience associated with these stimuli.
By using two-photon calcium imaging combined with electrophysiological recordings in awake behaving mice, our current projects investigate:
- How visually-guided behaviour modulates neuronal activity in the primary visual cortex
- How individual pyramidal neurons integrate feed-forward visual inputs with top-down contextual inputs.
- How cortical information processing relates to energy consumption
Using such information, we apply the same combination of methods to study how this network activity is disrupted in the brain of mouse models for autistic spectrum disorders and intellectual disabilities.
