2. “Men ought to know that from nothing else but thence [from the brain] come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations. And by this, in an special manner, we acquire wisdom and knowledge, and see and hear, and know what are foul and what are fair, what are bad and what are good, what are sweet and what unsavory.” Hippocrates, 460BC-370BC

3. What are the questions?

4. 5.What is a neuronal map, how does it arise, and what is it good for? 6.What is the role of top-down connections? 8.What is the origin and functional properties of irregular activity? 11. What is the formal computation in early vision? 12. Are neurons adapted for specific computations? 13. How can neural systems compute in the time domain 14. How common are neural codes? 15. How does the hearing system perform auditory scene analysis? 22. Do qualia, metaphor, language, and abstract thought emerge from synesthesia, 23. What are the neural correlates of consciousness?
