Virtual Retina

A biological retina modèle with contrast gain control for large scale simulations

Keywords: Neurosciences - Simulation - Biology - Health

Scientific Description: Virtual Retina has a variety of biological features implemented such as (i) spatio-temporal linear filter implementing the basic center/surround organization of retinal filtering, (ii) non-linear contrast gain control mechanism providing instantaneous adaptation to the local level of contrast, (iii) spike generation by one or several layers of ganglion cells paving the visual field.

Functional Description: Virtual Retina is a simulation software that allows large-scale simulations of biologically-plausible retinas.

News Of The Year: Virtual Retina software has been integrated into the platform PRANAS allowing to simulate retinal output via a graphical user interface (see paper published in Frontiers in Neuroinformatics, 2017)
