V1 and AL spiking neural network for visual contrast response in mouse (Meijer et al. 2020)


This code contains the computational model included in Meijer et al., Cell Reports 2020, which reproduces some of the main experimental findings reported --most notably, the higher sensory response of secondary visual areas compared to that of primary visual areas for moderate visual contrast levels in mice. The model is based on a two-area spiking neural network with embedded short-term synaptic plasticity mechanisms.
