Why do synapses of neurons degenerate and disappear? Shouldn t it grow indefinitely? 100 points 100

But why synapse.

Will it degrade or even disappear?

Synaptic senescence. What does synapses have to do with memories when they are not the product of nerve impulses?

Matter. Doesn't memory exist in the cell of a neuron?

Memory is the result of neuronal expression.

If synapses degenerate, do the body's synapses degenerate all the time? How does the human mind and feeling maintain stability?

It's always changing. But the change is relatively slow and relatively stable. So the thinking is relatively stable.

It happens when two meet.

Alas, I don't understand this! To put it bluntly, nerve cells also need to be metabolized!

After nerve cells are damaged, some "small shoots" can indeed grow. It's a pity that these little buds were just a flash in the pan and disappeared quickly. Why don't small buds grow big?

It turned out to be a nearby cell called "oligodendromyal", which "spit out" a chemical (called a "nerve growth inhibitor" by medical scientists) after seeing a nerve cell injured, which stifles the growth of nerve "shoots", so the higher nerve cannot regenerate, and it is at fault.

Another point is that I personally understand that during the embryonic stage, the cells around the neurons will secrete a nerve growth factor, which is necessary for the survival of motor neurons, and after birth, it is not secreted nerve growth factor, so motor neurons are difficult to regenerate.

Also, the nervous system is a complex network of neural pathways that establish the right neural pathways between nerves. Nerve axons are very long, and if they regenerate nerve cells, it is difficult to establish the correct pathway, which will affect the normal operation of the nervous system, so the body has to not regenerate.

As we ponder over the questions that we may never seem, the mystery of life, the answers to the universe, and so on, I think we may have taken a detour or even gone in the wrong direction so far.

Now we want to know the secrets of the universe, to explore the universe, I think a bit of a headache, foot pain, in the end is a symptom but not a cure, since the current scientific and technological means can not help us reach the edge of the universe or travel between the past and the future, so is there a shortcut?

I think the shortcut lies in our brain, there have been many cases of brain abilities in the world, and we also know that the potential of the brain is unimaginable, so can we say that the limit of human cognition lies in our brain, when the human brain can be 100% potential, teleportation, time travel, and even the mystery of life and the universe, which seem to us today, may not need to be achieved with the help of any scientific means, Can brains, which are less than 10% of their current potential, completely negate these possibilities?

What would happen if the human brain was developed to 100%?

Judging by the current development trend, it is not possible.

Maybe 10,000 years from now!

By that time, the amount of human wisdom and knowledge is estimated to be 10,000 times smarter than that of today's people.

It's time to conquer the universe.

Nobody knows, no one knows until there are no such people. If you are in the spirit of fooling the landlord I can say yes or no, but I don't want to fool you landlord, now no one knows!

You're watching too much, you develop it for me first, and when I develop, I feel that I'm telling you.

The brain accounts for 2% of the body's weight, but it consumes about 25% of the oxygen in the human blood, the brain is a high-energy-consuming organ, coupled with the harsh changes in the environment, the increase of carbon dioxide, the human brain has entered a negative energy state, what we need is more and fresher oxygen to supply and supplement the brain. The human brain develops 100% of the other physiological functions of our body is difficult to support, in reality, we can improve the function of the respiratory system through the training of abdominal breathing, and the lungs can be fully used, so as to absorb enough fresh oxygen, and provide sufficient oxygen to the brain through the blood, after which the brain can enter an excellent working state, and can develop unlimited intellectual potential. The improvement of human body functions needs to be synchronized, so as to achieve mutual balance and mutual support.

Our souls and minds always want to get rid of the shackles of the body, in fact, it is only when we die, when our imagination is open to the sky, do not forget whether our most fundamental body for survival can withstand it.

How to experimentally verify the conduction of impulses on nerve fibers.

Generate impulses and conduct impulses.

Mainly distributed in:

Brain, spinal cord, ganglia.

Neurotransmitters are synthesized before release and are packaged in synaptic vesicles, such as the neurotransmitter acetylcholine. When the nerve impulse reaches the presynaptic membrane, the synaptic vesicles move to the presynaptic membrane and fuse with the presynaptic membrane, and release neurotransmitters into the synaptic cleft through exocytosis, thus reaching the postsynaptic membrane and producing corresponding biological effects.

You can understand that you are prepared, ready to go, load the bullets first, and send them out when you receive the order.

Neurotransmitters are released after the generation of nerve impulses, and nerve excitation causes nerve impulses, and nerve excitation does not necessarily cause the release of neurotransmitters, which are produced in synaptic vesicles in the presynaptic membrane before excitation.

Neurotransmitter synthesis occurs prior to excitation and is stored in transmitter vesicles.

Transmitting nerve impulses, or analyzing nerve impulses.

The function of neurons.

Function of neurons: The basic function of source neurons is to realize information exchange by receiving, integrating, conducting and outputting ZHI information Neurons are the main components of the brain, and neuronal groups realize the analysis function of the brain through the information exchange of various neurons, and then realize the exchange output of samples. The resulting sample illuminates the consciousness of the mound through the connection path.

Nerve cells are higher than the higher ones.

The structure of the nervous system is single.

The zhi bit and functional unit DAO, also known as neurons. The neurological system contains a large number of neurons, with an estimated 100 billion neurons in the human central nervous system and about 14 billion in the cerebral cortex alone.

Function of neurons: The basic function of neurons is to exchange information by receiving, integrating, conducting, and outputting information.

The brain is composed of neurons, and the neuronal population realizes the analysis function of the brain through the information exchange of each neuron, and then realizes the exchange output of samples. The resulting sample illuminates the consciousness of the mound through the connection path.

The functional partitions of neurons, whether motor neurons, sensory neurons or intermediate neurons, can be divided into:

1) Input (receptive) area In the case of a motor neuron, the receptor on the cell body or dendritic membrane is the input area that receives the afferent information, and this area can generate a postsynaptic potential (local potential).

2) Integration (triggering impulse) region The initial segment belongs to the integration region or triggering impulse region, where numerous postsynaptic potentials occur in total, and when the threshold potential is reached, the action potential is first generated.

3) Impulse conduction zone Axons belong to the conduction impulse zone, and the action potential is transmitted to the target organ in a non-attenuating manner.

4) Output (secretion) region The synaptic bodies at the axon terminals are the information output regions where neurotransmitters are released through exocytosis.

The transmission of nerve impulses is unidirectional, not bidirectional, because conduction in the gap is a transmitter with unidirectional conduction First of all, it is a nerve impulse that is conducted, which is an electrical signal, not a memory; Second, each neuron has an axon and multiple dendrites, and nerve impulses can only be transmitted from axons to dendrites through synapses, not in reverse, so nerve impulses are transmitted in one direction between neurons; Third, motor neurons refer to axonal terminal connection effectors, while intermediate neurons connect to other neurons.

Not every nerve cell has it.

The transmission of nerve impulses is unidirectional, not bidirectional, because in the space conduction is the transmitter conduction in one direction.
