Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of th...

Hysteria is still too little understood, and too much the subject ?f loose thinking, even by psychiatrists. Any attempt to clarify our knowledge is therefore welcome : and the more so, when it is backed by an experience and an erudition such as Dr. Kretschmer's. And indeed we can cordially recommend his book to all doctors, who will find his concepts very helpful for themselves, and (in some ca...

The Jenner Lecturer this year was Sir Peter Medawar. In the title of his lecture he posed the question 'Is inoculation against cancer theoretically possible?' and he started immediately by expressing the opinon that he thought it should be. He presented this complex subject with great lucidity, beginning with a graph showing the relationship between the incidence of breast cancer and the age of...

Entanglement has been considered by E. Schrödinger [1] as: The most characteristic trait of Quantum Mechanics, the one which enforces its entire departure from classical lines of thought. Actually, the just mentioned unavoidable departure from the classical worldview raises some serious problems when entanglement of far away quantum systems is considered in conjunction with the measurement proc...

Recent studies suggest that lucid dreaming (awareness of dreaming while dreaming) might be associated with increased brain activity over frontal regions during rapid eye movement (REM) sleep. By applying transcranial direct current stimulation (tDCS), we aimed to manipulate the activation of the dorsolateral prefrontal cortex (DLPFC) during REM sleep to induce lucid dreaming. Nineteen participa...

Methionine sulphoximine (MSO) is a centrally acting neurotoxin which inhibits the glutamate metabolism enzymes and has convulsive properties. Small doses of MSO were administered to rabbits, either intravenously (i.v.) or intracerebroventricularly (ICV), and electron microscopic examination of the cerebellum, the spinal cord and the sciatic nerve was performed on the first day of rabbit hind le...

The article analyse errors which occur when airborne instruments are used and it creates basic idea about a chance of man (pilot) to receive correct indication his activity. introduces simplified model numbers measured values perception at short time some possibilities activity simplification can lead bigger lucidity efficiency using. As result is an alternative design optimization estimation b...
