NeuroComp/KEOpS'12 workshop beyond the retina: from computational models to outcomes in bioengineering. Focus on architecture and dynamics sustaining information flows in the visuomotor system. (2012)

Résumé : Survival is one of the evolutionary priorities for every species on Earth. It is strongly linked to making good decisions, even if these are unconsciously made. In the visual system, interactions between conscious and unconscious processing have been discussed, depending on the main two information ows originating from the retina: the Parvo and Magno pathways. We consider here a possible role of the Konio pathway; less studied and with di erent characteristics, such as large receptive elds for global complex event detection, and di use projections which may allow to quickly inform several areas in the brain of something im- portant present in the visual world. To test these hypotheses, we developed a computational systemic model of the early visual system proposing one type of Konio cells, which respond to certain spectral patterns and change the dynamics of the rest of the system accordingly. When examining the model's responses to static inputs, we observe that the system exhibits desirable reactions, together with time cost and e ciency characteristics. We also discuss the implications of the hypotheses for more complete survival and decision making processes, as the Konio pathway may only be a foundation stone for them in terms of evolution.
