Title: Contextual modulation of information processing in the mouse early visual system.
Affiliation: Tübingen University, Germany.
In the first part of my talk I will discuss how behavioural context shapes information processing in the mouse early visual system. I will present data from V1, dLGN, and the pupil, and show that locomotion de-correlates V1 population responses, affects response magnitude and selectivity at the level of the dLGN, and that locomotion speed is correlated with pupil size.
In the second part of my talk I will turn to stimulus context and discuss how cortico-thalamic feedback contributes to surround suppression in the dLGN. I will show that cortico-thalamic feedback modulates both temporal responses properties and spatial integration of mouse dLGN neurons. Together, this demonstrates that context can have profound influences on early stages of visual processing.
