Who Sleeps?
The Scientist and Jerome Siegel | Mar 1, 2016 | 10+ min read
Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.
Consciousness Studies: Birth of an Empirical Discipline?
Eugene Russo | May 9, 1999 | 6 min read
The Penrose-Hameroff Orch OR model places the essential aspect of consciousness at the level of quantum computation in microtubules within the brain's neurons. "Tubulin" proteins comprising microtubules can switch between states ("bits") and also be in quantum superposition of both states simultaneously ("protein qubits"). In the last several years, books, papers, and conferences have, with varying degrees of success, attempted to link the once-strange bedfellows of science and conscio
