A Talk on ‘Functional Organization of Cortico-cortical Feedback and How it is Shaped by Visual Experience’ by Radhika Rajan

ABOUT THE TALK
Contextual modulations play a critical role in shaping visual perception, a process long known to be shaped by visual experience. Cortical feedback (FB) projections are thought to underlie these modulations, but a comprehensive understanding requires knowledge of how visual experience influences the organization of these projections. We used wild-type as well as transgenic mice and simultaneous dual-color two-photon recordings of axons and somata to measure the functional organization of cortico-cortical feedback originating from the lateromedial (LM) visual area in primary visual cortex (V1). Our findings reveal that visual experience reduces the representational redundancy between feedback inputs and primary visual cortex neurons.

ABOUT THE SPEAKER
Radhika Rajan holds a BTech from the University of Madras and a PhD in Neuroscience from the Champalimaud Center for the Unknown, Lisbon, Portugal. Her research experience spans multiple techniques and model systems in neuroscience, owing to research stints at institutions such as the University of Geneva, Switzerland and the National Brain Research Centre in India prior to her PhD. Her PhD work focused on the visual cortical areas in mice.
