Feed-Forward Segmentation of Figure-Ground and Assignment of Border-Ownership
Figure 14
Scheme illustrating the mechanisms of figure-ground segregation by the model.
A neuron located on the figure region (left panels) receives weak global inhibitory input together with retinotopic excitatory input. As a result the neuron fires spikes. In the case when a neuron receives strong global inhibition and no excitation, rebound spiking occurs. Neurons on the background region (right panels) are silent. The strong global inhibitory input cancels the excitatory drive and weak inhibitory input does not produce rebound spiking.
