For raising these questions, it is commendable that you dare to think, hoping to maintain your fantasy of science. Perhaps the practice of these questions will achieve your ideals and goals in life. At this time, I think of Engels's famous saying. : As long as natural science is thinking, its form of existence is hypothesis (fantasy).
The brain is the most sophisticated organ in the human body, with 14 billion brain cells. However, modern technology - microsurgery - cannot be used on human brain tissue. Human research on the brain is far from this level, and the current level cannot be said to be transformation and optimization.
The current level of scientific understanding of the brain and brain cells:
"Brain Cells" (Encyclopedia Business Card)/view/152890.htm
Brain cells are composed of A general name for various cells of the brain. Brain cells mainly include neurons and glial cells (encyclopedia business card)/view/213009.htm. Take neuron (Encyclopedia - Definition of Scientific and Technological Terms)/view/36428.htm as an example: ?
The cell body (soma) of a neuron is located in the gray matter and ganglia of the brain and spinal cord. Its shapes are different. Common shapes are star, cone, pear and spherical shapes. The cell body is the metabolic and nutritional center of the neuron. The cell body varies in size, with a diameter ranging from 5 to 150 μm. (Human hair is between 70 and 90 microns: 1μm=0.000001m; take Einstein’s brain data as an example: it is the product of 25 billion neurons formed by the interaction of billions of nerves. A needle A brain tissue the size of a hoop usually has 50 million neurons and 1 trillion synapses! Einstein's thoughts fly through a maze of 150,000 kilometers of closed nerve fibers at a speed of 320 kilometers per hour. The human brain is so dense. High, when we talk about surgical removal on such a delicate, complex and narrow scale, and the prerequisite for transformation - the ultra-efficient working principle of the brain cell "network" is not yet understood by humans, how about the "removal" surgery? Carry out? How to talk about transformation).
What scientists discovered during their research is that the brain’s sophistication, complexity, the connection between brain tissue, the speed of information transmission, memory physiology, thinking processes, and autonomous consciousness are all amazing to humans: How can we have autonomy? Bionic computers with consciousness are also being developed, such as the Blue Brain Project: a plan to replicate the human brain conceived by Swiss scientists. To achieve the purpose of treating Alzheimer's disease and Parkinson's disease. But there are mixed reviews on the Internet. On August 11, 2009, scientists responsible for the Blue Brain Project announced that they are expected to build the first "thinking" machine in the history of science around 2020. It may have feelings, pain, desires and even fear.
As of July 2009, the project has made breakthrough progress. The "Blue Brain Project" team has completed the neuron calculation work of the neocortex part of the human brain and has drawn a 3D neuron activity simulation diagram. Ultimately, researchers hope to know and simulate the activity of neurons in the entire human brain to understand how the sensory information brought to us by the real world is deciphered and stored in the human brain, thereby uncovering the origin of human consciousness. puzzle.
Research and development: The "Blue Brain Project" was started in 2005. Its purpose is to reverse engineer the mammalian brain from experimental data. The research team focused on the cortical unit, a structure unique to the mammalian brain, also called the neocortex. This is a new brain, and mammals need it because they need to handle the complex cognitive functions of parent-child relationships and social interactions. It was so successful in developing from mice to humans that in order to generate this amazing organ, the number of brain structural units was expanded approximately 1,000 times. This research is still continuing and developing rapidly.
The human brain contains approximately 100 billion neurons, which are capable of rapidly interpreting and reacting to stimuli from bright sunlight, honking horns, the smell of fried chicken, and all other sensory organs. reaction. Now, someone is using IBM's supercomputer to simulate this mechanism of the human brain. This research plan is called the Blue Brain Project.
The project has a software model of "tens of thousands of neurons (each different) that will allow researchers to digitally build an artificial cortical unit. Although each neuron is unique, researchers have found Different brain wirings have different patterns.
To better understand the human brain's stress response, researchers in Lausanne, Switzerland, launched an ambitious project - the Blue Brain Project. The project uses IBM's eServer Blue Gene computer (which is capable of 22.8 trillion floating-point operations per second). The Blue Brain Project attempts to simulate 10,000 highly complex cells in the neocortical columns (NCC) of the mouse brain. Neuronal behavior. NCCs extend throughout the gray matter of the brain and perform advanced computing tasks. They are 0.5mm in diameter and are arranged in the brain like small grids in a honeycomb. Research level - National 11th Five-Year Plan basic scientific research, cutting-edge topics in brain science:
1. Microscopic research on brain cells and molecular mechanisms 2. Functionality: research on various functional mechanisms of the brain
"Basic Scientific Research" (Encyclopedia Business Card)/view/4625645.htm - Frontier Science 7. Brain Science and Cognitive Science:
Understand the human brain and its cognitive functions, It is one of the most challenging basic scientific propositions. The purpose of its research is to reveal the relationship between the brain and intelligence; to understand the nature of human cognition, intelligence and the origin of consciousness; to explore advanced aspects such as perception, consciousness, emotion, language, and thinking. Cognitive processes and their neural basis.
Main research directions during the "Eleventh Five-Year Plan" period: cellular and molecular mechanisms of brain function, mechanisms of occurrence and development of major brain diseases; brain development, plasticity and human intelligence. Relationship; neuro-information material omics; the intellectual development process and mechanism of the brain; the process and neural basis of advanced cognitive functions such as learning and memory; the basic expression of perceptual information, information processing and its brain integration mechanism; visual invariance recognition and brain mechanisms of selective attention; cross-channel collaborative memory, decision-making and epiphany problem solving; language cognition and automatic language recognition; development of autonomously programmable brain-based information processing systems and a new generation of artificial intelligence and design of brain-based intelligence Computers, etc.
During the "Eleventh Five-Year Plan" period, it is necessary to establish and improve a scientific research platform on brain, cognition and behavior, strengthen research on the molecular and cellular basis and mechanism of brain function, and strive to achieve advanced cognition in the brain.
