This test has been especially designed for the testing of medical, cosmetical and chemical substances, but also for the testing of the end products, like creams, lipsticks, mascaras, face-lotion, soap, shampoos, powder, hairspray, toothpaste, lacquer, detergent and everything, which could perhaps touch one's skin someday somehow.
The number of rabbits and other animals, which are killed by this procedure day by day, must be some millions.

Cigarettes are also "tested" by animals. Some years ago 86 dogs (race: beagle) were forced to smoke 455 cigarettes every day. This procedure took about one and a half year. After this time 12 of them got pulmonary cancer. Although this test doesn't say anything about the physical reaction of human smokers, it's still done with other animals.

A special kind of tube is inserted into the sheeps' neck-vein. Through this tube the sheep are connected with the dialysis machine. Different doses of test-medicaments are mixed into the blood. Then some blood-tests are performed. Athough a lot of sheep have repellent reactions like falling blood-pressure, difficulty of breathing, unrest, staggers and, of course, a lot of pain, the experiments are repeated seven times with changed conditions.

In this experiment the necks of the mice are cut open in the middle, so that the blood-vessels of the neck lie open and now some are contracted with loops.
A clamp is fixed temporarily at the inner artery of the neck so that the blood stream is stopped. After a cut into the other artery a tube is pushed forward to the brain, towards shut the middle cerebral artery. Some mice are infused a colouring substance into their hearts. A couple of minu ... mehr

On average you need 2 minutes to fall asleep.
Most people dream 5 times a night, humans will have about 136,000 dreams in a lifetime, spending the equivalent of six years in a REM sleep dream state.
Women usually dream much more passive than men do.
Students who study and get some good REM sleep retain the information better and longer periods of time than students who study longer, but have no sleep.
On average people chan ... mehr

On average, we spend about one third of our lives sleeping. Events in dreams may seem disjointed, and the ordinary logic of cause and effect may disolve. Dream characters may flout the laws of physics or behave in ways that seem wildly out of character. Indeed, when the mind is freed of its normal shackles, dreamers can radically reshape themselves and everything around.
Fantastical as the dreamscape may seem, however, it is not unfamiliar ter ... mehr

There are four stages of sleep in which the sleeping person sinks down:
. Stage 1: The first stage of sleep is a very light sleep. Stage 1 usually lasts just a few minutes. If the sleeper is not disturbed by anyone or thing, he or she will quickly journey into stage 2 sleep.
. Stage 2: This is much deeper sleep than stage 1. Dreams start to brew around here and although there are no clear images, vague thoughts and ideas drift through the ... mehr

There are 2 basic types of sleep: NREM, (non rapid eye movement) and REM (rapid eye movement) sleep.
NREM and REM sleep alternate during a normal sleep cycle. The beginning of sleep cycle is dominated by NREM sleep which gradually takes us into a deep state of unconciousness in which there is diminished brain activity, allowing blood to flow to muscles and organs. Researchers believe that during this period that the body has a chance to recove ... mehr

In 1953 sleep researchers led by Nathaniel Kleitman made the important discovery of rapid eye movement - or REM sleep. Curious about th long-standing observation that the eyeballs of sleeping subjects, in both, humans and animals, periodically move during sleep, they connected sleeping laboratory subjects to equipment that measured their brain waves (yielding an electroencephalogram, or EEG), muscle tone (electromyogram, or EMG) and eye movemen ... mehr

Good question... Many different theories, nothing for sure. According to the Freudian school, dreams are the result of subconscious thoughts and desires. The other extreme attributes dreams to random \"noise\" in the neurons without special meaning.
I do not agree with this last opinion, because I think that dreams really can tell us about ourselves.
Some say that dreaming gives us a chance to cope with stress and other emotional crisis that ... mehr

No one had ever tried timing a dream before, but many people had long subscribed to the opinion of French psycologist Alfred Maury, who postulated in 1861 that dreams were infinitesimally brief. It is also known as the popular 7-second-theory, but latest researches say that REM sleep periods, and therefore dreams, can even take 5 to 45 minutes. Anyway, time is one ot the perceptions that are heavily distorted in dreams.
But a scientist called ... mehr

Yes. Everybody dreams. Not only all humans, but in fact all mammals are shown to have REM sleep, which is associated with dreams. So if you think you don\'t dream you probably just don\'t remember.
Adult humans spend as much as a quarter of their sleep time in REM, integrating the constant influx of new information and shifting in to longerterm memory. By contrast, birds, whose behavior is so reflexive that they have little need to store memor ... mehr

Sensual \"input\" while sleeping is incorporated into dreams. Most notably, while sleeping, you hear as well as while waking - the ears are never turned off. This leads to the consequence that what you hear while sleeping, you will hear in your dreams. The sound is always coming from \"somewhere\". Common experiences of this kind are a telephone ringing or music from the radio. The same holds for the other senses. Note that it is not important ... mehr

Dreams seem to be a way for the subconscious mind to sort out and process all the input and problems that are encountered in waking life. Therefore, a scientist could be working on a problem... say the structure of the DNA molecule. Then said scientist could have a dream in which he sees two snakes interwining in a double helix. When he wakes, he has discovered the structure of the DNA molecule.
It was not \"a\" scientist. It was F.A. Kekeulé ... mehr

In the second century, a Greek named Artemidorus Daldianus compiled five volumes listing and attempting to interpret hundreds of events and items that appear in dreams. Recognizing how the dreamer\'s life would impinge on any interpretation, he well understood the difficulty of his task. Some 1,800 years later, researchers are still trying to catalog and analyze dreams - and the job has become no easier.
Studies depend on what dreamers report ... mehr

Recurrent dreams are a sign of thoughts that occupy the dreamer much, consciously or unconsciously. Such thoughts have influence on the dreams and they are often remembered better than \"random\" dreams since you somehow know their importance.
Sometimes those dreams are unpleasant, a sign or symbol of some conflict situation that you still have to overcome. Ask yourself what the dream signifies - probably you can interpret it better than anybo ... mehr
