Abstract(in English) | A wide variety deviations of illusory line motion are explained with a gradient model, that assumes the signal propergations from sensors to motion detectors are speeded by attention potential. However, physiological basis of the psychological model has been not clear. The paper proposed a physiologically plausible model for cortical neural network to control cell response delay by attention. The model incorporates both of D. Heeger's feedback model for response normalization and positive feedback amplification suggested with histological evidences. Adding to GABA-B type inhibition, GABA-A type inhibition to deep layer excitatory cells is assumed with disinhibition mechanism for voluntary attention effect. The model network is consistent with canonical microcircuit proposed by R.J. Douglas. The model incorporated with two-stage motion energy model brings a physiological plausible understanding of the illusory line motion perception. |
