 * &mdash; "Astronautic mission profiles require for the crew, various sleep-wakefulness cycles which are quite different from the normal diurnal rhythm. It has been found that there are means by which certain levels of sleep can be induced electronically without undesirable side effects. The paper describes the efforts made so far in the international scientific community and also the results of his own experiments."
