(linking idea with Brain Function)...and
(linking idea with Six Degrees of Separation)...
Basically, the whole relation of A to B, B to C and A to C, where
A to C can be replaced by addition of A to B and B to C also has impact on Brain Function...
The idea of Compensation, where one area of the Brain compensates for another could easily work by this principle.
This would assume that the brain sees the two possible paths in the same way and processes them quite similarly...
You could introduce any number of Vectors to replace one or more other vectors, and in certain circumstances may be of benefit...
Consider seeing something from another point of view...
Also, with the Six Degrees of Separation idea, links in with the whole Person A, Person B and Person C bit...
You may know someone through someone else, and constantly associate Person C with Person B, possibly to the extent that thinking of Person C without thinking of Person B makes little sense.
In the whole, you may tend to think of most people defined by a certain category in terms with those that share or do not share similar qualities...
Consider thinking of a particular family member...
If you think of them, you tend to think of similar people, like the other family members.
In this manner, linking one person to another, and then another, does kind of fit in with the Six Degrees of Separation idea...
So how do you manage to stay on the topic of one person or thought?
One answer would be due to the frequency of going through the point that symbolises a certain person, idea, etc...
This would mean that if you manage to link one idea with more and more ideas, when you think of that one idea it would be stronger than one that is not well linked, new or less meaningful...
***Be careful... Even if one idea is not linked greatly in number, it may well be linked to a few other ideas that are...
Hope this all makes sense...
Would love to hear what you think on the topic...
