What secrets and abilities does the human mind hide? Scientific studies and unbelievable facts on the human brain
Scientists sound the alarm: at the end of XIX century, people were much smarter and more creative than they are now. The fault is on the natural selection, since the more intelligent the person is, the fewer children he has, and vice versa.
Every new century humans become less clever and creative. This assumption was made by British scientists who studied the rate of the perception of people of the Victorian era, and the one of our contemporaries.
As the results of the study showed, the rate of general intelligence has been gradually decreasing. Thus, in 1889 the rate of perception in men was 183 milliseconds, while in 2000 it fell to 253 milliseconds. The similar tendency was observed in women – the speed of their perception has dropped from 188 to 261 milliseconds during the same period.
As said by The Telegraph, the diminished reflexes also indicate a decline in overall intelligence quotient (IQ), which is down by 1.23 points every decade, and since 1880 it has fallen by 14 points.
The researchers said they did not directly compare the IQ level of the representatives of different eras since the opportunities in education, medicine, and food of modern people are much better than the ones of previous generations. Though, according to the study authors, the high rate of perception in people of the Victorian era shows that they were more inventive and creative. (more…)
Resuscitation specialist Sam Parnia continues to darken already murky waters of thanatology, by offering his colleagues to carefully examine stories of people returned from the dead. In his view, which will be fully supported by any competent philosopher, these stories shed light on the nature of human consciousness.
“Consciousness does not disappear at death. There is no such discrete point in time. Death is a process,” he claims.
In the middle of the XX century, with the discovery of methods of cardiopulmonary resuscitation, the study of death has entered a new phase. Initially capable of resuscitating a person within few minutes after clinical death, now people who “died” more than half an hour ago (more…)
Experts from Harvard claim to have ‘crystallized’ the exact moment when the brain decides to perform an action or desire. This moment is not the same as the one when we think we have taken the decision. So does it mean that someone else ultimately take the decisions before we do?
In fact, the decisions are taken by the parts of the brain which “host” the subconscious, which has already made up its mind and announced it to the consciousness, located in another brain area. That is we learn later what our brain has decided for us. (more…)
“When people are frightened, intelligent parts of the brain cease to dominate”, Dr. Bruce Perry explains, quoted in an article published on the Time magazine website. When faced with a threat, the cortex responsible for risk assessment and actions cease to function. In other words, logical thinking is replaced by overwhelming emotions, thus favoring short-term solutions and sudden reactions.
On the other hand, interpretation of the environment helps us to survive disasters. Joseph LeDoux, professor of psychology at New York University, explains that this mechanism “monopolizes the brain resources to help face the threat”. (more…)
Scientists of the Duke University in North Carolina claim to have developed a “sixth sense” by using a special implant in the brain of experimental animals.
Lead researcher Miguel Nicolelis said that the results of the experiment led them to important conclusions and paved the way for a new set of prosthetic devices that can be controlled by the brain and may give us an opportunity to understand and “see” the infrared range of the electromagnetic radiation.
Lab mice were induced with infrared sensors, which were adapted to the area of the brain that is responsible for sensing information related to the touch. Therefore, once the animals perceived the infrared radiation, the brain interpreted it as “tactile stimulation”, resulting in the fact that mice did not see the beam, but could feel it, shaking the nose and scratching their fur.
