The power of Neurons and what makes me, ME!
The power of Neurons and what makes me, ME!
Inside of our skull there is a whole world. Interactions so fast moving, we don't even know they have happened before we react. Professor Gerbig once told me that a neuron can fire off 25 times in one second. Yet it does so faster than I can think about what it is doing. In fact as I think what to write my neurons have already fired out commands for my fingers to move and my eyes. The brain is a well organized machine. So mysterious and complex, that studying it often leaves us more perplexed than when we started.
Neurons are a mass of Dendrites, and Axons. They all group together and fire off in the same direction. It is by having these specialized cells we are able to think, and be aware of the world around us. They are hungry and hard working cells. Just a few minutes without air leaves them dying. They are faster than any computer and work from birth to death. In fact scientists are starting to find that when neurons do not fire off right, it does not send the steady signal to your lungs and heart to keep breathing and beating. So since the signal is lost due to errors in aging cells the heart stops beating and does not start again.
During our life time our neurons will do steady work. They will pick up millions of gigabytes of information, and every night while we sleep they will move that information from the front of our brain and the short term memory, to the long term memory. They will sort what is needed to be kept and where that information goes. After all we have pattern seeking minds, so logically we file everything with its pattern. For everything we learn a little of our white matter turns to grey, and we get a wrinkle on the brain. That is because new information causes a link between neurons. That link is made by dendrites. They are like wiry cables stretching from one neuron to the next, and crossing over. We are in fact hard wired.
So this is what makes us, us. Each new memory is filed, and out of it we get a lesson, or pattern. We learn what feels good and what hurts. We learn how to achieve, and how to avoid. We learn all about our world and as we do, it makes the person that you are a series of patterns flowing from cells that keep track of the you it made. Anyone who has ever suffered amnesia can tell you, they may never be the same person, but then they don't know that. Sometimes a familiar memory will trigger a connection that was created in the past linking their old pattern with the new, but sometimes they are changed forever. Just like people who suffer from Alzheimer's. They often lose who they are. Because when there is damage to the brain tissue and the connections between axons are severed we change. We are not really some sentient being. We are a bundle of cells clustered in a way that makes sense to us. This is why most of the time we don't see eye to eye with each other. No two brains are wired the same, and the closest we can get is twins. Probably because they share so many experiences, or their brains have a cellular plan that makes them structured similar.
But all we know of each other and of our selves comes from the great machine our skull works so hard to protect. What we are now can be changed in a heartbeat. Or with just a bit of brain damage. What makes us us, is the fact of how we are wired and the things we did, and nothing else.
Actually, I do have a little brain damage to the left side of my brain, but it only took away the last two years I had in college (I was 22 when I got it, am 27 now and it still affects my speech/right side of the body) but outside of that...am still a smart cookie!
ReplyDeleteI thought the wrinkle thing was just a myth.
ReplyDeleteSteven, if you had been younger, it could have turned you into a savant. Younger brains are more plastic, and can rewire themselves much easier, sometimes resulting in amazing abilities.
ReplyDeletePons is the center part of the brain and it will control all the system of all the body, i Guess
ReplyDeleteThis article was clearly not written by anyone with formal psychological or neuroscientific knowledge.
ReplyDeleteThe idea about memory is simplistic and incorrect, and the ideas about connections forming when new knowledge is learned are clearly influenced by the media. Specifically, there is no new "wrinkle" added to the brain when new knowledge is gained, and CERTAINLY no transformation of white matter to grey matter.
An "axion" is a theoretical particle - the author means axon.
Neurons certainly do not "group together and fire in the same direction".
All in all, a nicely written article with a good heart, sadly devoid of any scientific research, and irritatingly putting forward common myths and misconceptions as fact.

Hey mike I will get out my biology book for you...this is not psycology this is biology.
Delete"Dendrites are thin highly branched extensions that receive incoming stimulation and conduct electrical impulses to the cell body." So the impulse moves from dendrite to the cell body and out the axon. The axon is connected to the brain tissue. <- in bound signal
ReplyDeleteCell body.
The Axon is a single extension of cytoplasm that conducts signals away from the cell body. -> Out bound signal. The signal always moves from dendrite to axon. (Biology 8th edition 2008,pg 860)

Research Overview
Much like the computer, our brain relies on electrical circuits for all the functions. However, unlike the computer, the neural circuits are assembled from billions of nerve cells, each making thousands of synaptic connections through axons and dendrites, the long and thin extensions from the cell body. In addition, these connections are established during embryonic development and any misregulation could lead to early childhood diseases such as mental retardation. Furthermore, many axonal and dendritic connections can be remodeled even after the circuits are established, yet such ability appears to be diminished over time in the central nervous system, contributing to the great medical challenge in adult nerve regeneration.

I like you Mike, but really I try to not publish crap. Now the white matter/grey I think you have something there, but really the rest is from Bio class.
