Here you can find the list of former CIN members whose membership status was curtailed by a move to another location with no ties to the CIN, but whom we are still proud to count among our friends and partners.

Scientific topic: Neurophysiology of visual perception
Field of Research
Our work aims at investigating the properties of neuronal circuits and their fundamental computations. As sensory information processing always takes place in the context of behavioral goals, we are particularly interested in studying how neuronal circuit function is modulated by cognitive factors, such as expectations, attention, or decision making. To address these questions, we measure the activity of local neuronal populations using multi-electrode recordings and voltage-sensitive dye imaging in the visual system of awake, behaving rodents.
