The model detailed in the book, and referred to again in many of Edward de Bono's other books, is one of Neurones networked together by many stronger and weaker connections and activating as a result of input stimulus or stimulation from other neurones that are themselves active.

It is not intended that the model be a detailed analysis of how human brains are structured but the broadest possible abstraction that can provide a meaningful understanding of the nature of thinking.

More detailed models and theories specifically about the brain can be found under the topic of Cognitive Science and connectionism.

Attention tends to flow along well-worn paths and patterns have large catchment areas.

The techniques of Lateral Thinking are shown to be specifically designed to bypass these limitations.
