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 consumptionUsing 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.Funding ERC Consolidator grantBBSRC Research grant Sir Henry Dale fellowshipSimons Initiative for the Developing Brain (SIDB)BBSRCWellcome-UoE Institutional Strategic Support Fund (ISSF)RS MacDonaldMarie Curie Career Integration GrantMarie Curie Intra-European fellowship (Dr Janelle Pakan)Awards2019: EMBO Young Investigator (YIP) award2017: The Physiological Society’s 2017 R Jean Banister Prize Lecture2013: Schilling Research Award of the German Neuroscience Society 20132011: Bernard Katz Lecture Award, Alexander von Humboldt Foundation2006: Research prize from the French national association for the blind and visually-disabled people (FAF)Team membersDr Zahid Padamsey (Postdoctoral fellow; Royal Society commission 1851; BBSRC)Dr Danai Katsanevaki (Postdoctoral fellow)Dr Tom Flossmann (Walter Benjamin post-doctoral fellow; DFG, Germany)Dr Alfredo Llorca Molina (Postdoctoral fellow)Theoklitos Amvrosiadis, (PhD student; MRC Precision medicine DTP)Arthur Zhang (PhD student; MRC Precision medicine DTP)Zihao Chen (PhD student; SIDB)Patricia Maeso Hernandez (Research assistant)Lab alumniDr Janelle Pakan (Post-doctoral fellow, Marie Curie Fellow), now: PI, Pakan lab, DZNE Magdeburg.Dr Sander Keemink: now Assistant professor, AI department, Donders Institute, Radboud University Nijmegen, Netherlands.
