Implications
The three-dimensional AIM model shows that during the cycle of brain states waking-NREM-REM, the brain is dynamically changing constantly, and that this state space described by the AIM has an infinite number of subregions other than the main three. It proposes that via a protoconsciousness brain activation during sleep is necessary for the development and maintenance of waking consciousness and other higher-order brain functions such as problem solving. It proposes the idea that the state of waking consciousness is only present in humans due to the evolution of extensive cortical structures within the brain. Dreaming is a state of the brain that is similar yet different to the waking consciousness, and interaction and correlation between the two is necessary for optimal performance from both. One study conducted measuring brain activity via EEG used Hobson's AIM model to show that quantitatively dream consciousness is remarkably similar to waking consciousness.

Famous quotes containing the word implications:
“When it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.”
—Thomas Mann (1875–1955)
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
“The power to guess the unseen from the seen, to trace the implications of things, to judge the whole piece by the pattern, the condition of feeling life in general so completely that you are well on your way to knowing any particular corner of it—this cluster of gifts may almost be said to constitute experience.”
—Henry James (1843–1916)
