Congraulatory Sayings
One of the greatest mysteries of brain research is still the human consciousness.
How can we "know" that we do something?
What does it mean that I am aware that the previous sentence has been typed a few seconds ago by myself with my keyboard?
If we look in the mirror, "know" we maintain that it is "us" is.
We can hardly imagine a rational, functioning as something should, as seems logical, that an apple from his tree falls to the ground and not of it away because the gravitational attraction to other masses of earth works (and vice versa).
exist Nevertheless, something that makes us believe at least, we would be more aware. As with the intuition believe the consciousness of many people because it is something "higher" handle. The specific nature of consciousness that is understandable. I find this explanation unsatisfactory, however ...
The functioning of the brain could be viewed as follows:
Our brain is estimated at about 100 billion neurons, each about 1000 connections to other neurons.
Our thoughts are about a term was firing electrical impulses, these compounds.
Our body is constantly in a flood of information, the input that is processed including by these pulses.
takes place after which this processing mechanisms and the influence hormones and other substances it is still unclear.
But one can assume that this information be represented in some way in the brain again. I call it that Neural Representation (NR).
The NR is an abstract reflection of reality.
This could, for example by a combination of different firing rates among a group of neurons can be realized. Each neuron then has a specific task.
(eg that with a rate of 50 times per second to neuron fires No. 345, by 1000, with which it is connected)
also whenever an alarm is called, comes out of this NR remembered. Memories would therefore be only a storage of these neural representations. What
NR submits itself to a neuron, is determined on which it receives impulses from other neurons. At a special pulse image is in turn reacts with a special Feuerate to other neurons. Precisely how it responds to what, therefore, is a Puzzlestueck the memory of an NR. As the exact Puzzlestuecke be saved is another question (current studies suggest that they could be in the DNA sequences of neurons).
Since this is only an abstract reflection, NRs are no complete figures of the input, according to internal priorities but an orderly representation of the original information. The internal Priotaet depends on the agreement with the sum already stored information from other NRs.
also plays a role, which enjoys priority information with other NRs (external priorities). Smaller external priorities have a smaller influence on the sum of all coincidences.
is this that increases with decreasing compliance of internal priority. For less agreement means greater individuality. The smaller internal priority, the less the information in a NR is taken into account.
If we become aware of a memory now, that means that we try using a NR a spiritual, to create the actual input view (not just visually). The
Unvollstaendigheiten be completed with the help of other NRs, often occurring when information is preferably as similar as possible NRs.
If we become aware that if we see a house, it's a house, we compare a created from the new input REF of the house with old NRs and NRs with similar verpnuepfen it then. Linking could be saved with their NO.
There are also NRs also that we represent themselves. Our output, we can also recognize as input and compare with older NRs ourselves.
When we think about ourselves is that that is a constant comparison between our own person, of NRs.
