The brain is full of silent synapses.

There are millions of silent or cold synapses in our brains. In this text, the terms "silent", cold and dead synapses mean the same thing. We are using only a part of our brain potential. Sometimes some researchers created models to increase the number of used neurons. But those ideas have remained at the philosophical level. 

There are reserve neurons in the brain. That mission is to replace neurons that are in danger. When the brain must renew some of its neurons. It must transfer all memory blocks stored in that neuron to the next generation. The memory blocks that are gone with dead neuron is the reason. For we say that "neurons will not renew". 

When memory blocks stored in the neuron are gone, the next generation neuron cannot make the same missions as its successor. 

There is the possibility that those silent neurons are used only in early brain development. That means when brains are in progress. Those silent synapses are used to create and control the neural networks forming at very young ages. 

The large number of synapses that are not in use must have some purpose. The brain will not make anything that has no part in its entirety. Some people believe that those used synapses are needed when people are sleeping. 

There is a possibility that the human brain uses different neural tracks for sleeping. And especially when the person sees dreams. When a person sleeps the neural network loads its neurotransmitters. And maybe some of those cold synapses are meant for secondary connections. 

The reason why the brain is full of "dead" or silent synapses can have a connection with renewing neurons. The cold synapses might be reserved for transferring data to the next generation of neurons. Or maybe those cold synapses are meant for interaction between the brain and immune cells. 

That means those cold synapses send neurotransmitters to immune cells. And of course, they can receive neurotransmitters. The reason that makes those cold synapses interesting is that everything in the brain is important. 

There is no part in the human body without purpose. And that makes neurology so fascinating. We cannot remove anything from the human body without knowing its function, or we can make very large-size damage. 

Knowledge about the cells ad their actions in the human body is important in medical research. The medicines must affect only the points where they are useful. If medicine affects too large areas, that thing means that they turn harmful. 

And one problem in medical research is how to make medicine separate harmful cells from helpful cells. The medicines must not destroy things like neural structure. If it makes that thing, it causes very bad damage. And that's why medical researchers need precise information about the human body.

Could the spacecraft be a cyborg?

Some researchers introduced an idea to send genetically engineered microbes to Alpha Centauri. In the most incredible ideas, the researchers send the small probe to the nearest solar system by using laser rays. The laser ray will push that small probe to route to Alpha Centauri. 

Sometimes introduced an idea, that by using cloned neurons is possible to create spacecraft that intelligence is similar level with humans. The problem with those biological computers is the aging of the DNA. And stabilizing the DNA is the key problem in interstellar space missions. 

Cosmic radiation fibrates the genetic material of those cells. That causes damage to the DNA. And this is why there must be something that protects those cells against cosmic radiation. 

There are two ways to make that thing real. 

*The system can use cryogenics. In cryogenic systems, those neurons are feezing in temperatures near zero kelvin. Also, cells that create nutrients for those neurons must be stored. 

*Or the system can use active cells. That requires the closed nutrient cycle that cleans and recycle the nutrient for those artificial brains during long space journey. 

In the most conventional version of this cyborg android UFO, developers store those brain cells in the spacecraft. They will put those cells in the cryogenic capsule. During the long journey, the AI controls the craft. When that craft is near its destiny the AI will melt cells. 

And then they would get nutrients for the mission. In that version, the required information is stored in those neurons. The idea is that the BCI (Brain-Computer Interface) will use to teach those neurons. The system requires a complicated closed nutrient cycle, which is very difficult to make. 

*********************************************'

Genetically engineered brain cells can transfer memories between humans. 

The idea about genetically engineered neurons that hybridized with fungus as the brain of robots or robot spacecraft is taken from the myth that "some Egyptian god is a fungus". The source of that myth is that ancient Egyptian priests used psilocybin fungus for hallucinations. 

And in some versions, the fungi were some of those gods. Maybe some priests that used those mushrooms too often told those stories. But that myth is used for making models for parasitoid aliens. 

The idea is that the neuron-fungus hybrid can take other creatures under control. And one of the theoretical parasitoid aliens is mushroom-fungus hybridization. And if those neurons could travel between bodies. 

Some futurologists introduced a model that memory neurons that took from the brain or where the BCI-system transmitted information can transfer memories between humans. The idea is that researchers can transplant those cells between humans. And at the same time, the memories travel to the new body. 

That thing could explain the metempsychosis. The thing is that metempsychosis is in this version the memory cells that are traveling from the dead body to the next host body. Maybe that thing is possible in the future. 

***********************************************

But could those neurons be awake during the mission? 

In the most incredible versions of that spacecraft, the cloned neurons will control that spacecraft. The idea is that there are three layers of cloned neurons. That are forming artificial brains. The system requires that neurons can get nutrients during the flight. And of course, dead neurons must be replaced by new ones. 

For success, that kind of system must have a closed nutrient cycling system. That system can base on the genetically engineered neurons that hybridized with fungus. The system can use bacteria as nutrients and the cells can have pre-programmed genomes inside them. At first, the cells start their lives as part of the fungus that takes nutrients for neurons. Then that fungus cell transforms itself into a neuron. 

And after that, its mission will be to replace the dying neurons. The system will recycle dead neurons into nutrients for bacteria that are feeding the ecosystem. This kind of cyborg can be possible in the future. And in some visions UFOs:s are machines that are driven by AI or living neurons.
