Some of the yet unsolved problems of neuroscience include: * (Self-)Awareness: What is the neuronal basis of subjective experience, wakefulness, alertness, arousal and attention? What is its function? * Perception: How does the brain transfer sensory information into coherent, private percepts? What are the rules by which perception is organized? What are the features/objects that constitute our perceptual experience of internal and external events? How are the senses integrated? Is face perception special (e.g. inert)? What is the relationship between subjective experience and the physical world? * Learning and Memory: Where do our memories get stored and how are they retrieved again? How can learning be improved? What is the difference between explicit and implicit memories? H
