VR may cause vomiting – Because of motion sickness
VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
Old age mental activity – number of neurons
Old age mental activity – number of neurons – The decrease in mental activity in old age
was attributed to the decreasing with age, the number of brain cells.
Neurologists from universities in Boston and Washington, however, proved.
That almost all of the 10 billion cells used while thinking, they are active even in 80-year-olds.
Alcoholism effects – Repairing damaged neurons
Alcoholism effects – repairing damaged neurons – Scientists from Wurzburg in Germany
found that damage to brain cells caused by excessive alcohol consumption can be repaired only partially.
They note that in the interest of alcoholics is the fastest return to sobriety. Longer heavy drinking
causes brain regeneration proceeds with great difficulty.
Impact hair thinking – Hair arranged in the left side
Impact hair thinking – Hair arranged in the left side – Researchers from the University of Bonn
have discovered that only a small part of the population. Hair around the crown arranged to the left.
They proved that the hair arranged in the left side may have a similar effect on the functioning of the brain
as writing with left hand. Thus confirming the theory that describes the stacking of hair left
almost exclusively left-handed persons.
Men and women brains weight differences
Men and women brains weight differences – Researchers under the direction of Paul Farmer
of Harvard Medical School in the US have shown that the size of certain parts of the brain in women
is different from the same part of the brain in men. The frontal lobe in which the center of
decision-making and problem-solving, weighs more in women than in men. More space is also an area responsible for short-term memory and spatial orientation.
Physical exercises beneficial effects
Physical exercises beneficial effects – Have a positive impact on the level of neurotrophic factor BDNF,
which promotes growth, improves communication and survival of neurons. A diet rich in healthy fats,
for example. Omega-3 fatty acid, nourishes the brain tissue, where fat plays a key role – creates
a sheath cellular and myelin.
Brain Map – Computer atlas of the biochemistry
Brain Map – American scientists have provided online computer atlas of the human brain. The project cost approx. $ 55 million. During the development of the atlas was examined and mapped the biochemistry of two brains of adults. With the obtained data it shows that human brains combines 94% rotation-similarity. Atlas is similar to the multi-purpose GPS system – the brain identifies landmarks in 1000 based on over 100 million data points each biochemistry and genes that reveal in it. Atlas is available at www.brain-map.org.
Difference between brain hemispheres
Difference between brain hemispheres – At approx. 98 % of right – handed and at approx. 70 % of left – handers speech centers are located in the left hemisphere. The right hemisphere was described as a non – verbal, visual – spatial, simultaneous, holistic and intuitive. While the left as verbal, rational, sequential. Functional asymmetry of the hemispheres of the brain means that one prevails over the other. They perform complementary roles in the processes of thinking. Although the function of each hemisphere of the brain is different, it is equally important for the proper functioning of all mental activities.
Synthetic exendin – Previously only from saliva
Synthetic exendin – Eli Lilly & Co. has developed synthetically exendin – 4. Previously only obtainable from the saliva of the Gila monster (Heloderma suspectum) – one of two venomous lizards in the world. Living in the deserts of the north – western Mexico and south – western United States. During the manufacturing process used the latest methods of biogenetics. Exendin is intended for the treatment of type 2 diabetes has become a forerunner in a new series of drugs known as mimetic (imitation) incretin. They imitate the action of incretin hormones found in nature. In addition to the pancreas incretins also affect other organs in connection with the regulation of glucose – liver, kidney, muscle and brain.
