Keywords become even more useful if they are linked together in patterns in which the central or main idea is in the centre of the pattern, the relative importance of each idea is indicated, and the links between the key concepts are immediately recognisable because of their proximity and connections. The structure of such mind maps allows for the easy addition of new information, and each pattern will look and be different from every other pattern, making recall and review both more effective and more rapid. In the more creative areas of note making, such as essay preparation, etc., the open ended nature of the pattern enables the brain to make new connections more readily.

The memory and retention of mind maps can be greatly enhanced by the use of colours, geometrical shapes, arrows linking similar concepts, comments, etc. Similarly, the use of humour (especially if vulgar, absurd, or sensual) in the selection of keywords often increases the retention or recall of information, although linkages which are too witty, abstract or confused will not usually be particularly helpful.

Applications of mind mapping are endless: including stimulating and recording the results of thinking; organising information, data or tasks; preparing the first drafts of reports, books, specifications; the making of schedules of appointments or tasks; in planning strategies, campaigns or work; in the analysis of data or events; in making précis of books or reports; and in helping to make decisions. Indeed, the ability to hold large amounts of information in structured patterns which reveal the inter-relationships between concepts and values, usually on a single sheet of paper, often transforms the ability of individuals to think creatively and effectively. It is only surprising that the technique is not more widely known and taught as an essential component of modern education.

Extending the basic idea of mind mapping to the acquisition of new information gives additional emphasis to the importance of structured thinking and note-taking. By dividing the reading, etc. through which the new information is acquired into separate stages of overview, preview, inview, and review, study can be made a personal, interactive, continually changing and stimulating experience, rather than a rigid, impersonal and tiresomely onerous task.

Although mind mapping is essentially a technique requiring only a pencil and a sheet of paper, computer programs exist for recording and printing mind maps, and can be very useful. Really extensive records of information which require dozens, and perhaps, hundreds of separate mind maps can be accessed and linked through the use of the computer, and the patterns printed for the purposes of communication.
