Curiosities of Psychology
There are people who can't forget
Have been described cases of people capable of remembering almost any data or event just by experiencing it once. They are cases of prodigious memory that usually involve a tragedy for those who suffer from them. Forgetting is necessary for our mind to evolve.
The ancient Romans when they had to tell the truth in a trial ...
instead of swearing on the Bible as it is today, they did it by squeezing the testicles with the right hand From this ancient custom came the word "testify."
The hormone called corticosterone ...
that segregates In times of anxiety, he is responsible for the sudden loss of memory. This hormone blocks the recovery of information up to an hour after the stress situation ceases. This would explain, for example, that some students remain blank on exams. The calm, the brain recovers data.
Half of children with high abilities fail in studies
8 percent of children in our country have depression ...
and 40 percent suffer from stress.
The brain weighs an average of 1,380 grams in men and 1,250 grams in women.
It contains some 100,000 million neurons, approximate figure of the stars of our galaxy. And its almost 100 trillion serial and parallel interconnections provide the physical basis that allows brain function.
70% of the mentally ill are unemployed
The percentage of employment after hospital discharge is between 10 and 30%, only 10 to 15% keep their work between 1 and 5 years after discharge. Unemployment constitutes a primary index of disability, so this situation accentuates the isolation and stigmatization of the mentally ill in our society.
There are several types of amnesia
Retrograde amnesia is the rarest but the most cinematic, in it the affected person does not remember his life before the injury. In contrast, in anterograde amnesia, the most common and serious, the patient remembers his past but fails to learn anything new.
There are many other memory abnormalities, such as prosopagnosia or inability to remember faces;
el déjà vu, feeling of having already lived something; or hypermnesia, which allows you to remember different things in detail. A classic case of the latter, referred to by psychiatrist Taine, is that of the illiterate housekeeper who recited (even without understanding them) whole paragraphs in Latin, Greek and Hebrew heard from an uncle of her child. Another case of extraordinary memory capacity is that of the Russian reporter Solomon Veniamin, who could learn in seconds and repeat without any error, from top to bottom and diagonally, huge lists of figures and words. And the most incredible, weeks, months, even years later, reproduced them exactly.
In the year 500 a. C. the Greek poet Simónides de Ceos devised the "system of places" to remember the situation of some diners.
Simonides was at the banquet when he was briefly absent, thus saving himself from being crushed by the collapse of the ceiling; and he was the only one to be able to recognize the broken bodies of said diners by remembering the places where they were sitting.
A true Fakir master can do much more spectacular things than endure the punctures laid on his bed of nails,
although they seem less spectacular. It can, for example, make half of the palm of your hand warm ten degrees more than the other part, it can stop your heart for a certain time, or you can reduce your vital signs to a minimum by entering a state similar to that of the Hibernation of some animals.
The first psychiatric hospital in history was built in Baghdad in 792.
Sigmund Freud, the creator of psychoanalysis, became interested in his youth for drugs
Specifically investigated the properties of cocaine. He took the drug himself in small doses and made self-observations on the effect it had on hunger, sleep and fatigue. This research lasted three years (from 1884 to 1887) and Freud intended to make an important discovery in the field of the clinic or in the pathology, but it was not. At first he was fascinated by the fact that cocaine raised mental and physical vigor, without apparently having any harmful effects. But soon they began to be published in medical journals of the time that prolonged use of cocaine could produce a "delirium tremens" very similar to that of alcohol. The young Freud who wished to benefit humanity with his research and make a name, was accused of having caused a new disease. He also had a painful experience, believing that cocaine was safe, had prescribed a significant amount to a patient, who died because of it.
The brain of humans is the one that has more folds of all living beings
Therefore if we deployed it would measure approximately 2 meters, while the one of a gorilla, everything and weigh almost the same, when deploying it only measures a quarter that of the man.
The female voice causes exhaustion in the male brain
According to Professor Michael Hunter, from the University of Sheffield (Great Britain), the tone of the female voice has more complex sounds than the male, so it takes the entire auditory area of the male brain, while the voice of man only occupies the subthalamic area. Hence, on many occasions women complain that hunger does not listen to them, since what they do is "disconnect" for a purely physiological reason.
The nerve stimuli inside the brain are transmitted,
thanks to the neurons, at a speed that exceeds 400 kilometers per hour.
Each neuron is responsible for establishing communication with several hundred or even thousands of neurons in its environment.
If all the neurons of our nervous system were put in a straight line, they would be several hundred kilometers long.
