From: Beyond inhibition: lateral modulation of plasticity of feedforward synapses in a spiking model of V1

Figure 1

A. Detail of the heterosynaptic rule. Neurons N1 and N2 fire early for the input, and their feedforward synapses undergo normal STDP. They send an activity signal to N3 and N4, whose feedforward synaptic weights are then depressed to prevent learning of the same feature. B. Map of measured emergent orientation and phase responses of neurons in a 2 × 2 degree section of V1 layer 4 of our spiking V1 model. We observe a wide range of oriented feature selectivity and good spatial coverage of the feature space.
