The hard problem of consciousness is finding an explanation for how physical phenomena acquire subjective characteristics becoming, for example, colors and tastes.[1] For example, "it is possible to know all the physical and functional facts concerning the operation of human brains without, for example, knowing what it is like subjectively to experience vertigo."[2] As stated by Goldstein:[3]
| ‘ | Solving the "easy" problem of consciousness involves looking tor connections between physiological responses and experiences such as perceiving "red"... This is also called the search for the neural correlate of consciousness. Solving the "hard" problem of consciousness involves determining how physiological processes such as ions flowing across the nerve membrane cause us to have experiences. | ’ |

The term hard problem of consciousness usually is attributed to David J. Chalmers.[4]
Some, perhaps most, scientists believe this problem ultimately will be explained by the developing methods of neuroscience:[5]
| ‘ | What we do not understand is the hard problem of consciousness — the mystery of how neural activity gives rise to subjective experience. Crick and [Christof] Koch have argued that once we solve the easy problem of consciousness, the unit of consciousness, we will be able to manipulate those neural systems experimentally to solve the hard problem. | ’ |

A kind of inverse to the hard problem that concerns the relation of physical causes to the subjective, is the problem of mental causation, the query as to how, or even if, mental events, like decisions, can cause physical events.[6] One facet of this topic is the placebo effect: does it indicate a real physical effect of the mind (perhaps via the brain) upon the body?[7]
| ‘ | “The study’s results shocked the investigators themselves: even patients who knew they were taking placebos described real improvement, reporting twice as much symptom relief as the no-treatment group.” | ’ |
