Edge Detection and Motion Discrimination in the Cuneate Nucleus
In this paper we investigate how the cuneate nucleus could perform edge detection as well as motion discrimination by means of a single layer of multi-threshold cuneothalamic neurons. A well-known center-surround receptive field organization is in charge of edge detection, whereas single neuronal processing integrates inhibitory and excitatory inputs over time to discriminate dynamic stimuli. The simulations show how lateral inhibition determines a sensitized state in neighbouring neurons which respond to dynamic patterns with a burst of spikes.
