Does the Brain imitate Google?

A recent studio assures that the great searcher of internet works as a human brain, linking millions of web page from a similar way to the neurons.

When Google entered in our lives, you still showed up before that population of Internauts petty as the "most automated" searcher. In this time (you already make more than one decade) the search engines were quite mediocre and subjective, for blame of the human intervention. More than searchers, were really index aligned by people and, therefore, they were not neither all the agile one, neither all the quick one, neither all the massive one that you began to be necessary to navigate for internet.

Google entered then as the self-operating alternative: this novel searcher's operation was based on a combination of algorithms that you/they were those that distilled the best result in feature of mathematical parameters of quality, such as the relevancy, the iteration and the importance.

And now, passing the first decade of the invention, you seem that the novelty was not such: because our brain searches the memories in a way more or less similar. The searcher that almost succeeded for your humanity" "ullage thinks as us.

How many more links, well
The key is PageRank: this algorithm is the one that solve how result will obtain when searching in Google, and you are based on a combination of factors that you/they "punctuate" each page from 0 to 10. You are a parameter of "relevance" on the remainder of contents that make that they highlight some places on others in feature of the punctuation that you/they are granted. And the most determinant element when granting that punctuation is the number of links: each link supposes a point, but not all compute in the same way. Because you are not the same as you link us the CNN that MySpace of an adolescent. The secret is the prestige.

According to a recent report in the New magazine Scientist, the operation of our memory is very similar to this architecture of nodes and networks. You could explain this way to you how neurons and synapsis are conjugated when to remember and to sort our memory, in a very similar way to as you make it PageRank of Google.

Tom's studio Griffiths consisted on comparing the words that a group of people associated in first instance to the letter TO (and then the B, and so forth) with those that Google returned before a search; in a surprising way, the results coincided: the searcher and the humans gave the same list of words for each letter. The studio group evoked the same "first terms" that the searcher, what took to the psychologists to the curious conclusion that the connections that settle down among the cells neuronales were very similar to the links of internet.

According to Griffiths, the neurons that you/they enjoy many connections become more enabled and more effective (or what are the same, more noted) than the remainder, in the same way that those webs that possess many links is appraised how more important for Google.

Comparative memory
For the neurologist María Sacrarium Boatman, the human memory works as a flowing" "trunk of data that you/they can be compared among them. To demonstrate it, coarse a petty game: "When we try to memorize those that are named non words (invented terms, nonexistent and without meaning)", the expert you explain, we "memorize with much more easiness those that sound similar to actual terms that are already stored in the 'semantic" store of the memory." You are about a structure of very similar organization of data, for example, to the form in that Google sorts the pictures in your searcher of images.

The searcher of internet appraises more the popular contents, and the memory prefers the most moving.

1. In feature of the success
GOOGLE: When we start a search, that makes the motor you are to sieve among the millions of pages that he/she have read already, to choose those that it consider better (generally, those more visited and linked).

BRAIN: On the other hand, our memory puts above the mere information, of the pure and cold data, those memories that you/they go accompanied by some meaning with emotional imposition.

2. Terms key: search handles
GOOGLE: Certain word count that you/they describe the content of a certain web makes easier than the searcher you fix in them.

BRAIN: In a same way, our memory reacts in an active way before having determined words or images "fetish" that you/they boost us and they bring back our memories.

3. The interest: the approaches of 'quality"
GOOGLE: You give to each page a punctuation that depend (for command of pettier to more importance) on the number of visits, the content and the quantity of links.

BRAIN: The memory also appraises the links: plus those that tie a certain memory with sensorial (odors, flavors.) information that make it more alive.

Extraneous and Exotic Mental Disturbances

Mr. P. he/she was an eminent musician that had gone to the query of a neurologist because he/she had problems to identify the things of their environment. In some occasion they had surprised him/her giving pats in the part higher of the fire hydrants believing them children's heads or starting a conversation with the latch of a gate.

This way, it inserted their wife in the conceptual same category that an umbrella or a hat.

One of each 200 subject with chronic tics can end up suffering this dysfunction of genetic origin.

Tricotilomania
It is a wrong that he/she suffers near the population's 1%. The sick person starts the hair of any body part compulsively: head, brows, chest, pubic field...

Blind vision
The patients seem completely blind, at least regarding a part of their visual field. If they are asked if they can see an object in that field, the answer is negative. But if they are forced to point out where he/she is that object, it will indicate the correct place. Somehow, their visual mechanisms have been discontinued. They can see, but they are not aware of it.

Syndrome of the Foreign Accent mark
50 cases localized in this stranger's dysfunction world that arises exist when different connections of the control rooms of the language in the left side of the brain suffer a damage. Some patients generate a language standard totally different to the own one. In certain occasions, the individual ends speaking with accent mark different to that of his country or an unrecognizable tongue, product of the mixture of several languages with those that he has had contact.

Blindness to the movement
A very strange variety of blind vision. The patient sees the static objects well, but you/he/she doesn't perceive the movement. If it tosses the coffee in a cup, it captures without problems the coffeepot, the plate, the cup... but the stream appears before its eyes like an icy and immobile column. It is a not well disabling one. The cars, people, the television images appear and they disappear suddenly at different distances, but they get lost as soon as they move. The well-known few cases have taken place after a brain-vascular accident.

Mental disturbances of other countries or exotic

Amok
It is given in the island of Java and Indonesia, it is a dysfunction in that the individual, after suffering a social (it is generally given in men) strong shame, begins to run even destroying all that finds to his step, killing the animals unceasingly and to people to that you trips in his road.
