FUSION: Functional structure of the retina: A physiological and computational approach

Project Summary

This project aims to better understand the retina's response to complex visual stimuli and unravel the role played by the lateral interneurons network (amacrine cells) in this response. For this, we will adopt a dual methodology: experimental and computational. Using real-time control and feedback loop we will exploit a computational model of the retina to adapt, in real-time, visual stimulations to recorded retinal cell responses. The experiments will be done in Valparaiso (Chile).

The BIOVISION team will develop the control software and extrapolate results at the Inria Centre at Université Côte d'Azur based on its recent theoretical advances in retina modelling, in collaboration with R. Cofré (U. Valparaiso and  NeuroPSI CNRS). This is, therefore, a transdisciplinary and international project at the interface between biology, computer sciences, and mathematical neurosciences. Beyond a better understanding of its network structure's role in shaping the retina's response to complex spatiotemporal stimuli, this project could potentially impact methods for diagnosing neurodegenerative diseases like Alzheimer's.
