wine Posted January 14, 2007 Report Posted January 14, 2007 This thread weaves into the harmonization of every eyeand all the locations of neurons that are known in our human bodies. This thread is a division of possibilities, please participate. So far I know there are neurons in The Brain, and in The Heart.Do you know where any other neurons are? (Fireflies):confused: Experiment 1: Think about your brain, maybe even close your eyes and really think about it. Next, think about your heart. Think about compassion, and love. Not just the emotion, but recall memories that stem from the Heart.Try to think about thinking WITH your heart, as if it were your brain, as it is a division. (I would also call that activating your heart chakra, oh but I know everyone has their own atomic definitions.:thumbs_up ) Kind of strange this new realization is it even true?It must be, right?Are there enough neurons for these memories?Maybe the neurons in the heart are like switches that get a LOT of help from the brain, I'm sure. This thread is to further understand the neuron, and it's biological locations on our map. Does anyone know if there are research groups that are still looking for more neurons in the body?I...would really like to do that. Quote
Boerseun Posted January 14, 2007 Report Posted January 14, 2007 There are no neurons in the heart. The heart is muscle tissue. You can't think with muscle tissue. The ability to "think with your heart" is purely metaphorical, and refers to thoughts of an emotional nature. Seeing as that's the case, then sure - metaphorically, there are neurons all over your body. For instance, if you see a sexy girl, you seem to have a lot of neurons downstairs. Quote
ronthepon Posted January 14, 2007 Report Posted January 14, 2007 And, if it's the biological 'neuron' you talk about, then you'll find them everywhere in your body. They make up something called a nervous system, which is responsible for control and coordination in your body. Quote
wine Posted January 14, 2007 Author Report Posted January 14, 2007 So one of you says there aren't neurons on the heart, and one of you says there are neurons all over the nervous system. Are there really neurons all over the nervous system? Where can I read more about this? Quote
PsyCho Posted January 14, 2007 Report Posted January 14, 2007 And then their funky relatives dendritic cells, hurrah for complex systems Quote
InfiniteNow Posted January 14, 2007 Report Posted January 14, 2007 So one of you says there aren't neurons on the heart, and one of you says there are neurons all over the nervous system. Are there really neurons all over the nervous system? Where can I read more about this? The Brain—Information about the Brain However, any good university will have links available to you as well.

wine Posted January 14, 2007 Author Report Posted January 14, 2007 So there are really neurons and dendridic cells all throughout our nervous systems? What are dendridic cells? Thanks for the link Infinitenow, will check it out...now. Quote
InfiniteNow Posted January 14, 2007 Report Posted January 14, 2007 What are dendridic cells? Thanks for the link Infinitenow, will check it out...now. So, the nervous system is (this all based on memory, please forgive any minor errors) made up of axons. Coming off the axons, like branches of a tree or fingers off our arm... are things called dendrites. The dendrites reach out and form a basic connections with the axons around them. It's these connections that really matter. You've maybe heard the term "neural mapping." The more connections that an axon makes with the axons around it, the better it can communicate. There are little chemicals that are released called neurotrasmitters, NTs, (seratonin, dopamine, etc.) and these float in the space between dendrites and the other axon. When those NTs reach the other axon, a reaction occurs and the (electrically based) signal propogates. I'll let the link I gave explain the rest, but you can get some radically cool images by searching for the term "golgi stains." [img=http://microscope.olympus.com/ga/products/fv300/appli/Images/03.jpg]http://microscope.olympus.com/ga/products/fv300/appli/Images/03.jpg[/img] Just be cautious with the literature. Many topics use the term dendritic cell as part of the immune system, or in the growth of metals, and that's clearly a bit separate. :phones: Visualization of Dendritic Growth wine 1 Quote
InfiniteNow Posted January 15, 2007 Report Posted January 15, 2007 Holy shnikey... I just found an uber cool site. Check out the following for some visuals on neurons (it's a 52 second streaming animation, and is very impressive): LONI: Laboratory of Neuro Imaging A complete understanding of neurovascular coupling is crucial for interpreting functional imaging data and normal brain function. Neurons have an intimate relationship with astrocytes, smooth muscle, endothelial cells, pericytes, and erythrocytes. Neuronal chemoelectrical activity is speculated to be linked to several metabolic cascades, collectively known as neurovascular coupling. Neurovascular coupling includes the followed events: Glucose is metabolized to lactate in astrocytes, the lactate is then shuttled to neurons and metabolized with oxygen to form carbon dioxide and ATP. Arteries deliver oxyhemoglobin to neurons, and oxygen is then released in the presence of carbon dioxide, thus converting oxyhemoglobin into deoxyhemoglobin. Nitric oxide or neurotransmitters such as acetylcholine released by active neurons cause relaxation of smooth muscle in arterioles, thus increasing blood flow and volume. Functional brain imaging techniques such as EEG, PET, fMRI, or OIS detect the changes during one or more of these events during neurovascular coupling. Quote
HappytheStripper Posted January 15, 2007 Report Posted January 15, 2007 Hi .. I recently read an article about a Antarctic Polar expedition where scientist will study neutrinos.. the article stated millions of neutrinos float through our body every second.. as waves of energy.. Food for thought.. Ashley Quote
wine Posted January 15, 2007 Author Report Posted January 15, 2007 So I just googled "Neutrino" and I want to ask all of you what you think it means to have 50 trillian neutrons passing through your body (?) right now:shy: :shocked: :edizzy: :ebluehair :angel: :angel: :applause: :D :D ;) :D :D :alien_dance: :alien_dance: :alien_dance: :alien_dance: :alien_dance: Quote
Buffy Posted January 15, 2007 Report Posted January 15, 2007 So I just googled "Neutrino" and I want to ask all of you what you think it means to have 50 trillian neutrons passing through your body (?) right nowWell, it doesn't mean a whole lot, since the likelihood of them hitting even a single proton or neutron (not neutrino, not neuron, all three completely unrelated for those who are really looped by the direction of this thread!), is pretty much beyond Mr. Spock's ability to compute odds. All those smilies did more to me just now that all the neutrinos that will ever pass through my body in my entire lifetime. Transteleporting to da cooler... What if my neuron sparked jim-bob's neuron, :D Buffy Quote
CraigD Posted January 15, 2007 Report Posted January 15, 2007 So far I know there are neurons in The Brain, and in The Heart.Correct. As Ron points out, neurons are found nearly everywhere in the body. They’re what carry the electrochemical signals that allow us to sense touch, heat, cold, pain, and move our muscles. The heart is connected to the brain by a particularly dense and important cluster of neurons known as the vagus nerve. Though important, the best current understanding of how memories are formed and recalled is that they require collections of neurons found only in the brain. Therefore, it’s believed that all but the most primitive, reflex-type information can be encoded in nerves outside of the brain. A rough analogy is that the brain is like the CPU and memory in a computer, while the neurons outside of it are like the keyboard USB ports, and any other sort of peripheral wiring. Though built of similar stuff, and intimately connected, neurons outside of the brain simply aren’t made to hold memories, and don’t need to, being so intimately connected to the brain. A notable difference between the brain and the neurons in the rest of the body are that Glial cells appear to exist only in the brain. While glial cells aren’t themselves neurons, so don’t directly carry neurochemical signals, they have synapses that interact with those of neurons, and play an important role in supporting and arranging neurons, an important but only partially understood role in thought and memory. Neurology and neurophysiology are arguable the most complicated and least completely understood branches of biology. Fortunately, the last 30 years, have been a “golden age” of brain science, especially the last 10, when significant knowledge in the field nearly doubled every year. Though some major challenges and technical barriers lay ahead, it’s not unreasonable to expect that, within another decade, we may really understand how it the brain works. Neuroscience has the exciting feel that I imagine physics did around the 1690, when Newton and others were beginning to convincingly connect the dots in Physics. Quote

Based on the 11/2/1999-1/15/2001 SNO results, a 100 kg human being (which is pretty much the same as 100 kg of water) should interact with 1 solar neutrino every 10 years. Each interaction will either transmute one atom into element with the next highest or lowest atomic number, or jar lose 1 electron. Such an interaction is too weak to trigger a signal or reconnection of a neuron, and about as close to not happening at all as can be found in physics. Those neutrinos sure are weakly interacting!

Buffy Posted January 15, 2007 Report Posted January 15, 2007 How dare you impugn the sacred, fictional reputation of Spock! ;)I overstate. Let Leonard Nimoy or Majel Roddenberry or Paramount sue me for slander. Go ahead. Make it so.Even a lowly human like me can calculate the odds...I'd take Craig's word over Spock's any day!...a 100 kg human being should interact with 1 solar neutrino every 10 years.Captain! We're under attack!Those neutrinos sure are weakly interacting!WIMPs! You know the story. Girl meets boy, girl changes boy's subroutines, :DBuffy Quote
wine Posted January 16, 2007 Author Report Posted January 16, 2007 I read that some neurons can be a meter long.What happens when that neuron dies?Does it...metabolize? Quote
