The CIMeC Colloquia Series is an annual set of invited talks given by leading researchers in the mind/brain sciences, both from Italy and abroad, aimed principally at our PhD Students. Given the multi-disciplinary backgrounds of the CIMeC students and researchers, the Colloquia are aimed at a general scientific level rather than at a more specialized audience.

TITLE: Interactions between visual cortical neurons for perception and restoring them for the blind
ABSTRACT: Our results implicate early visual cortex in visual cognition - in tasks where subjects reason about what they see. I will discuss new evidence supporting the hypothesis that the activity in early visual areas has a causal role in cognition. I will discuss how the neuronal responses emerge as the interaction between brain areas, with a special role for specific classes of interneurons. The early visual cortex acts as a multiscale cognitive blackboard for read and write operations by higher visual areas, which can thereby efficiently exchange information. These results also inspire new approaches to create a visual prosthesis for the blind, by direct interfacing with the visual cortex. I will discuss how high-channel-number interfaces with the visual cortex might be used to restore a rudimentary form of vision in blind individuals.
