List of unsolved problems in neuroscience
There are yet unsolved problems in neuroscience, although some of these problems have evidence supporting a hypothesized solution, and the field is rapidly evolving. One major problem is even enumerating what would belong on a list such as this. However, these problems include: Consciousness Consciousness: How can consciousness be defined? What is the neural basis of subjective experience, cognition, wakefulness, alertness, arousal, and attention? Quantum mind: Does quantum mechanical phenomena, such as entanglement and superposition, play an important part in the brain's function and can it explain critical aspects of consciousness? Is there a "hard problem of consciousness"? If so, how is it solved? What, if any, is the function of consciousness? What is the nature and mechanism behind near-death experiences? How can death be defined? Can consciousness exist after death? If consciousness is generated by brain activity, then how do some patients with physically deteriorated brains suddenly gain a brief moment of restored consciousness prior to death, a phenomenon known as terminal lucidity? Problem of representation: How exactly does the mind function (or how does the brain interpret and represent information about the world)? Bayesian mind: Does the mind make sense of the world by constantly trying to make
