Research Summary

Andrea  Benucci(Ph.D.)

Our laboratory studies the neural basis of sensory processing with a major focus on vision. We are particularly interested in understanding the computational rules used by populations of neurons in the visual cortex to process visual information: how does the coordinated activity of groups of neurons, “talking” among each other via action potentials, produce a visual percept? What are the relevant spatial and temporal scales used to process visual information? To address these questions, we are using as a model system the primary visual cortex of mice trained in behavioural tasks. The experimental tools we are using are based on cutting-edge methods in Optogenetics, optical imaging, and electrode recording. This research provides an ideal test-bed for understanding the neural mechanisms of visual perception and its outcomes have the potential to provide important clinical applications in the field of cortical visual prostheses.
