Tony Buzan, the creator of Mind Mapping, defines The Mind Map is an expression of Radiant Thinking and is therefore a natural function of the human mind. It is a powerful graphic technique which provides a universal key to unlocking the potential of the brain. The Mind Map can be applied to every aspect of life where improved learning and clearer thinking will enhance human performance. The Mind Map has four essential characteristics:

1. The subject of attention is crystallised in a central image
2. The main themes of the subject radiate from the central image on branches
3. Branches hold a key image / word printed on the associated line - details radiate out
4. The branches form a connected nodal structure.
