Nathalie Rochefortcut4 CopyInvited by Serge Picaud and Valentina Emiliani, Nathalie Rochefort, Professor of Visual Neuroscience at the University of Edinburgh, Scotland, will give a talk on Wednesday, Friday 5th at 11.30 AM (Salle Schiff, 15-20 Hospital, 3rd floor)

This talk will be dealing with "Vision in action: contextual signals in visual cortex".

"The global aim of my research is to reveal how cortical neuronal circuits process visual 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. Recent results have shown that neuronal responses to visual stimuli are modulated by the animal’s behavioural state (e.g. level of arousal) as well as its previous experience associated with visual stimuli (e.g. their association with a reward). In order to investigate the circuit and cellular mechanisms underlying these context-dependent changes, my research group is using two-photon imaging methods and high throughput electrophysiological recordings in awake behaving mice.

I will focus my talk on two recent projects from the lab investigating:

  • 1. How visually-guided behaviour shapes neuronal activity in the visual cortex
  • 2. How cortical information processing is impacted by metabolic state."

"Nathalie Rochefort is a Professor of Visual Neuroscience at the University of Edinburgh, studying the neural basis of visual perception. As an undergraduate, she studied Biology and Epistemology in Paris. She then obtained a European PhD in Neuroscience from the University Paris-VI and the Ruhr-Universität-Bochum and did her post-doctoral training at the Technical University in Munich. Her work during her PhD and post-doctoral training has contributed to a new understanding of how neurons acquire their functional properties in the visual cortex. This work also led to the development of in vivo two-photon calcium imaging, a powerful technique now widely used by neuroscientists. Her research group focuses on how brain neuronal circuits process visual information, and how experience durably modifies the activity of these circuits in health and disease. She has won various honors and grants including the prestigious Bernard Katz Lecture Award, the Schilling Research Award of the German Neuroscience Society, the Sir Henry Dale fellowship (Wellcome Trust and Royal Society), the EMBO Young Investigator award and the ERC Consolidator grant."
