ELC_V1_Simp.0   Equiluminance cells (ELCs) are created within a spiking network model with connections from the retinal to V1. These cells (the EX_RG population) respond best to red-green boundaries at equiluminance. They are constructed by a combination of inputs from double-opponent inhibitory units, luminance sensitive inhibitory units and direct single-opponent LGN input. This model supposes that ELCs may exist in V1, although they have only so far been reported in V4 (Bushnell et al. 2012).
