Are you talking about the brain reflex theory?

1905165438+1Senov, who founded the brain reflex theory on October 2nd.

1 August, 8291day, sechenov was born in Kurmeishi county, Novosibirsk province. He was lively and smart since childhood, and his parents and teachers liked him very much. 1850 was admitted to Moscow university medical school to study medicine. 1856 after graduation, he went to Germany for further study and engaged in scientific research. At that time, the science and technology of tsarist Russia was still relatively backward, and some western scholars and professors often treated Russian students with contempt and discrimination. A German professor named Ramon once said to his Russian students: "People with long brains (referring to Germans) have all possible geniuses; And short-headed people (referring to Russians) can only imitate others even under the best circumstances ... "sechenov was very angry at this blatant contempt and absurd fallacy for him and his motherland, and vowed to learn technology well and win glory for the motherland.

Sechenov returned to Russia on 1866 and became an associate professor of physiology at Moscow University. During this period, Sechinov's research focused on the reflex of the nervous system. He first experimented with frogs and put one of their hind legs in a cup full of sulfuric acid. As a result, the leg shrank back as soon as it touched sulfuric acid. This reminds him of a series of other reflex phenomena: the hand was pricked and quickly retracted because of pain; When the eyes are illuminated by strong light, they will blink; Pat the knee tendon; The calf will jump. In order to find out the physiological mechanism of reflex, he decided to do experiments on himself with sulfuric acid. He asked his assistant to bring a glass of sulfuric acid solution and quickly inserted his finger into the solution. Universities all know that sulfuric acid solution is a strong corrosive agent, and people will be scalded when they touch it. When Sechinov put his finger into the sulfuric acid solution, he gritted his teeth and held his breath, and with amazing willpower, prevented his hand from retracting. After a while, Chechinov's pain eased and gradually disappeared. This brave experiment revealed to him an important physiological phenomenon: through the control of the brain, people have the ability to suppress strong external stimuli (physiological or psychological). That is to say, when people's nervous system is strongly stimulated by the outside world, they can't make corresponding reactions (actions).

1863, sechinov published the book "brain reflection". This epoch-making psychophysiological book scientifically explains human psychological phenomena for the first time, pointing out that all conscious and unconscious activities in human life are the result of brain reflection. He pointed out that without the initial stimulus from the outside, the reflex could not happen.

After sechenov's theory of reflection was put forward, it was hated by the czar government, and the book Reflection on the Brain was banned. The court also accused Sechinov of immoral research on the brain as an organ. However, truth cannot be stifled. Sechenov eloquently proved with his own precise experiments that there is a very close relationship between the brain and the nerve reflex, and the human brain is the highest command to manage the reflex. The theory of reflection founded by sechenov has finally been recognized by the world.
