Abstract
We investigated the early visual pathways with a neuroscientific model representing the retina and the lateral geniculate nucleus.<br>We trained a recurrent, convolutional deep neural network to generate a firing rate activity consistent with the lateral geniculate nucleus behavior. The training dataset, composed by videos (inputs) and spiking times (targets), was generated through a physiological model we replicated from literature in pyNest. Then, we simulated an intraneural stimulation by imposing a custom activation to a selected central layer of the model.<br>Our results proved that recurrent, convolutional deep neural networks can be applied to simulate and analyze the early visual processing pathways.
