On February 26, 2015, the JBC presented the Symposium: The Predictive Brain : Hierarchies in Sensory Processing. The symposium opened with Prof. Merav Ahissar's lecture on Hierarchies and Reverse Hierarchies in Skill Acquisition, how skills can go from high to low and from low to high depending on one's experience. Prof. Naftali Tishby spoke on Predictive Information and Emergence of Perception and Planning Hierarchies, how when making a choice, someone's knowledge may determine outcomes. Prof. Stefan Treue's talk on Attentional Modulation of Visual Motion Processing along the Dorsal Pathway in Primates, dealt with how our senses provide much more information to the central nervous system then can be adequately processed. We use attention as a powerful selection mechanism for focusing processing resources on the small fraction of incoming information that is behaviorally relevant at a given moment. Prof. Shimon Ullman demonstrated, Atoms of Recognition in Human and Computer Vision. He explained how the human visual system makes highly effective use of limited information: it can recognize not only objects, but severely reduced sub-configurations in terms of size or resolution.
