11. INTRAUTERINE DEVELOPMENT OF THE CHILD AND ITS FEATURES

Periods of embryonic development of a child:

1) initial (first 7 days of development);

2) embryonic (from the 2nd to the 8th week of pregnancy);

3) fetal (from the 9th week until delivery).

By the 8th week, the embryo begins to acquire the features characteristic of a person. In the process of embryonic development, a person goes through several crisis stages associated with the formation of his individual systems.

During the stable period, the adoption stage (from the 8th to the 16th week of pregnancy) and the intrauterine infant stage (from the 20th to the 28th week of pregnancy) pass through. The crisis stages are the stages of otherness (this stage occurs from the beginning of pregnancy to the 13th week) and fetality (from the 15th to the 22nd week of pregnancy).

Let's consider these stages in more detail. The first stage in time is the crisis of otherness. This is the moment of conception of the child and its acceptance by the mother's body, that is, the initial stage of the formation of the fetus.

The second stage is the acceptance stage. At this stage, the fetus is accepted by the mother's body, her awareness of her own pregnancy. The third stage is the fetal crisis.

During this period, the fetus begins to actively manifest itself, that is, move. A mother, feeling her child, can respond to his movements (for example, by stroking), develop his sensory abilities. The fourth and last is the developmental stage (or the intrauterine infant stage). During this period, the active formation of the fetus continues. It increases in size, more and more acquires the features of a person. During this period, the mother and fetus emotional connection becomes more stable.

By the beginning of the 3rd month, it is already possible to speak about the development of the sense organs and the brain centers corresponding to them. Already at six weeks, you can fix the work of the brain, at seven - synapses begin their activity. This is the period of the first reflexes.

A three-month-old fetus can already feel the touch, he begins to actively move. The auditory system begins to form from the 8th week. The formation of the inner ear begins first, followed by the outer, and by the 5th month the process of formation of the entire auditory system is completed.

Sight and smell are also formed during the prenatal period, but unlike tactile sensations and hearing, they do not manifest themselves in any way until the moment of birth.

This is their difference from the taste, which the child begins to demonstrate early enough, which affects the needs of the mother.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Sleep doubles memory efficiency 06.08.2015

Scientists from the University of Exeter (UK) found that on the eve of the exam you need to get enough sleep - and thereby double the efficiency of memorized information.

Sound and healthy sleep is extremely beneficial for the brain's ability to retrieve information from memory. Sleep is able to save information from involuntary forgetting, as well as provide faster access to memories.

British scientists conducted a study to determine how effectively people remember made-up words. Test participants were asked to learn a set of words, then try to remember them, and finally do the same after 12 hours, during which one group was asleep and the other was awake.

The results showed that the participants performed poorly on the task immediately after the “cramming”, but after 12 hours of rest they were able to remember much more. However, the group of people who indulged in healthy sleep at that time showed almost twice the best result.

Thus, scientists believe, fresh memories are processed and "reinforced" in the brain while we sleep. Further research will help to understand in more detail the effect of sleep on the mechanism of remembering information.
