在脑图（MIND MAPS）发明人托尼巴赞（Tony Buzan）的网站上，对脑图是这样定义的：
A Mind Map is a powerful graphic technique which provides a universal key to unlock the potential of the brain. It harnesses the full range of cortical skills–word, image, number, logic, rhythm, colour and spatial awareness–in a single, uniquely powerful manner. In so doing, it gives you the freedom to roam the infinite expanses of your brain. The Mind Map can be applied to every aspect of life where improved learning and clearer thinking will enhance human performance.
Originated in the late 1960s by Tony Buzan Mind Maps are now used by millions of people around the world – from the very young to the very old – whenever they wish to use their minds more effectively.
Similarly to a road map, a Mind Map will:
Give you an overview of a large subject/area.
Enable you to plan routes/make choices and let you know where you are going and where you have been.
Gather and hold large amounts of data for you.
Encourage problem solving by showing you new creative pathways.
Enable you to be extremely efficient.
Be enjoyable to look at, read, muse over and remember.
Attract and hold your eye/brain.
Let you see the whole picture and the details at the same time.
Assist YOU!
