Discrimination of Motion Direction in a Robot Using a Phenomenological Model of Synaptic Plasticity

Figure 1

Architecture of the microcircuit. There are 6 units in total. Subpopulation 1 (red) forms a cluster of 3 units, each of which exhibits a preference for stimuli moving towards the right. The remaining units in subpopulation 2 (blue) display higher responses for stimuli moving towards the left. Connections are bidirectional, with self-connections allowed. Outgoing connections from units within both subpopulations exhibit STF.
