how do neural circuits form?
ParticleOne replied to gib65's topic in Anatomy, Physiology and Neuroscience
There is no exact rule for how the conscious part of the brain makes the synapse element enhancements. I guess you elude to training and faster communication, but it is more complex than just finding a short-cut, you can be pretty sure that nodes B-C-D have a say in the process and by bypassing these will cause that the same information is not transmitted E as if it took the "long route". Take a look at http://online.itp.ucsb.edu/online/bblunch/laughlin1/ “Design of a Brain”, it will not give you a direct answer to your question, but still interesting. -
lack of sleep and brain damage
ParticleOne replied to abskebabs's topic in Anatomy, Physiology and Neuroscience
Since all the facts are not established yet (work in progress) I will explain this in an unscientific way: Sleep is more important than we have understood. All mammals sleep, and it is a necessity for survival just as feeding. Feeding is also a necessity for neurons, but for the complex conscious part this is a problem while functioning. It is almost like trying to refuel an open burner with gasoline while it is burning. You have to extinguish the flame before you refuel, otherwise you have a problem. That’s why the neuron has to close for the possibilities to fire while “feeding” otherwise the firing will be uncontrolled, and this blocking is sleep. We experience dreams or “random” firing in the transition time of blocked and waking up (or semi-waking) to normal function of the neuron. If we do not sleep or sleep poorly over time the conscious and subtle analytical part of the brain will be exhausted and loose the ability to stimulate other parts of the brain, which is vital. We experience it especially for our immune system, without sleep we are especially vulnerable to infections, but also possibly other immune-system related diseases. (Experience have shown that a rat dies from infections if kept from sleeping over longer periods (2-3 weeks)). Neurons have for a long time been neglected as cells with a major immune-regulatory function because they do not express major histocompatibility complex class II. New data show that neurons are highly immune regulatory, having a crucial role in governing T-cell response and possible T-cell development. This could lead to malfunctioning T-cell development resulting in diseases we know are immune-system related. -
Beauty of relativity: Speed = c

I'm a bit confused. Insane_alien: If I take your example of waves on a pond (it cannot be EM field) then it would mean that as an electron changes its valence band it "drops" some energy into some field which causes waves, but these waves have to be omnidirectional then? (Aether theory, which is not proven OR disproven?) If so, then I have a problem with tests from the National Synchrotron Light Source at Brookhaven National Laboratory, where photons where captured at distinct points.? Swantson: I agree, the wavelength of light is far longer than size of a nucleus, and I agree that in the far-field it will be regarded as a point source, but from a sub-sub nm point of view it must still have a direction from the atom. And it must still be GIVEN a direction?

Hello Atheist, I know it is a controversion issue, but that photon have the feature of always having speed c is not suficient explanation. Wether choosing a particle or wave function, the speed must have a reason. Even if it is massless, pure energy must have a reason to displace itself, and thats my question. Why grass is always green has an explanation, the photosynthesis absorbs only red> and <blue frequencies of light and reflects the green colors, no matter where they live. Regarding the direction of radiation: If a photon is released as a quantum process of electron moving from higher to lower valence band, in theory it could take any direction, i.e. it could "collide" with the nucleus if it was released in that direction. But it is always released perpendicular outwards from the nucleus. Why?
-
What force is giving radiation (light, gamma and all other EM) its exact same speed c, wether it originates from an electron or nuclei, and what determines the direction, always directly away from the particle's core?

OK, I see that there is a need for a proper explanation of time, this important measurement which is used to calculate a number of physical parameters/occurrences. Eon: - You touched on a very important factor regarding perception of time, which is also why the question of "what is time" has repeatedly been asked over centuries. Initially I will restate what I indicated in a previous post: Time is a human defined measurement of movement (occurrences). Time is a passive measurement without any influence on any physical occurrences. Usage example; Using the natural frequency of a caesium 133 atom (used as standard for time measurements) we can count the number of waves it takes an object to move from point A to point B. If we have measured the weight of the object and the distance between A and B we can say something about the speed and forces involved. The number of waves is what we have defined as time. Now we introduce the totally confusing element needed to make sensible use of our measurement: MEMORY. Memory is not an element in physics per se, but an element we add to make sense of physical parameters. Already counting the number of waves we use math and memory to total the number. In us, humans, the memory element is a built-in part of any evaluation our brain is doing, and there is nothing we can do to stop that function, we might as well try to stop thinking ANYTHING while awake, it can not be done. Imagine if you were walking down the street and you were wiped of memory, you are moving, but have no recollection of where you were a second ago, hence no awareness of time, but you are moving. Then imagine a single point of energy, totally alone in space (universe) nothing else. This point was really full of energy but nothing to use its forces on. (You are not present) And there is no time, not even a little caesium atom. What you automatically think is: But time is passing and the little point is just sitting in space waiting? It is impossible for you to think otherwise. Now, if I removed all memory from your brain, would you know how long the little point has been in space? No. you would not know if time had passed or not, or if there were any time at all, and neither will the point of energy which has no memory. All of a sudden another point of an opposite energy appears out of nothing, some distance away from the first point. They feel attracted to each other and use their forces to meet. Now I will give you some memory and a caesium atom so you can count the waves from the second point appeared and until they clashed. Now you can say: Hey, I’ve got the time, 858 million waves from start of movement till they met! But that’s all you have. Time does not bend, time does not compress or stretch, but how you manipulate the data is a different issue. There are perfect answers to time dilation etc. but that’s for another discussion.

Here is one for you to answer: You and a friend are sitting in a hot place with a cube of ice in front of you. You want to leave, but your friend says, let's give it some time and we will watch it melt. And so it does. Question: Was it you giving your time or was it the heat that melted the ice cube?

It is really interesting to observe all the confusion about time, but at the same time it is understandable. Time is a human invented measuring parameter for movement over distance. Early measurement of time was night and day based on earth’s movement around the sun, but modern science requires exact measurements over very short time, and in order to do that we are using the resonance frequency of a stable caesium 133 atom which gives us 9 192 631 770 fractions of a second, sufficient for most measurements. Why do we forget so easily? We invented and specified what the time parameter should be, and now we are turning around asking what time is? We do not question so much what a meter distance is, and we specified that parameter too. Time is a totally passive measurement, and can not influence any physical parameter, forces do, and that’s what we are measuring. The confusion starts when applying time measurements to confusing and complex forces and we start to mix forces, movement and time measurement as all influencing parameters. Let’s take a hypothetical where we take away some influencing parameters: Imagine you took a video camera that showed exact time with the picture and you moved far away from the masses in the universe and started filming the galaxies, stars etc. Since we are at a hypothetical level we will also ignore the speed and deflections of light and call it instant and straight. Suddenly two stars far away from each other exploded at the same TIME according to the picture and the time shown in the camera. So two thing happened at the same time billions of lightyears apart and it is recorded and the clock shows the same time. Now we will face a little reality and reinstate that light travels as a certain speed c so it will take some time from the event till it shows in the camera. If we record the same event, but now with light travelling at speed c. Now our recording shows that the first explosion according to the clock was at 11:00 one day and the other explosion at 15:00 the next day. If we had no knowledge of the influencing parameters we would say that the two events took place 28 hours apart. Since we now are fairly enlightened we know that we need to look into the conditions for the measurement. First we need to know the distance to each star from the camera, then we need to know the escape parameters for the light from the star until it was not influenced by the stars gravity or media it had to travel through which slowed the speed down and also if it had been curved along the way to the camera so it had travelled a longer distance than we thought. In other words we need to know a lot of parameters in order to qualify the time measurement. But our measurement (time) was passively waiting as a number to be compensated for the physical parameters that influenced time of the event till the light that told us about the event reached the camera. Our time measurement could do nothing about it, but the parameters influencing the speed of light would influence our measurement. A mix of the passive and active elements would cause confusion. So to the classical question: if time is a measurement of movement, does time stop if the object we are measuring does not move? No, as long as there is any reference anywhere there is something moving. If there are no references or anything moving anywhere, we have nothing to measure.

Assertion: Mass is a closed, balanced particle (core and shell) of opposite polarity "energies" adjusting its internal distance at resonance frequency featuring asymptotic freedom. The "Photon" is circumferencing "energies" (same amount as mass particle and featuring asymptotic freedom but not resonating), free to move and not binding to other particles. Rotating frequency and direction depends on release factors. Observed as wave.
