BRIGHTNESS ESTIMATION IN A NEURAL NETWORK MODEL WITH PRESYNAPTIC INHIBITION

Recent psychophysical and neurophysiological investigations showed that visual systemencodes luminance and use it to estimate illumination and surface brightness. We proposed anovel neural model for luminance coding based on recurrent inhibition, from the retinalganglion cells to the axons of the bipolar cells, which modulates the amount of sensory inputthat ganglion cells receive (Sagdullaev et al., 2006). Extended version of the model, where...
