Spiking neurons can code stimulation strength in firing latency. This latency code carries the same information as firing rate, but is readily established in a few milliseconds. The brain can employ this fast and accurate time-based code for the processing of homogeneous stimulation. We have proposed that the koniocellular path of the visual system performs spatial homogeneity detection. Here, we present a model implementation of this process, using a spike-latency code. In a network simulation, we demonstrate the fast detection of spatially homogeneous luminance. We also demonstrate, how the homogeneity threshold can be dynamically adjusted. We achieve this through the shaping of synaptic potentials by forward inhibition.
