In theory, at least, brain imaging could Dan Ariely and Gregory S. Berns illuminate not only what people like, but also what they will buy. Abstract | The application of neuroimaging methods to product marketing — Thus far, this approach to neuromarketing neuromarketing — has recently gained considerable popularity. We propose that has focused on this post-design application, there are two main reasons for this trend. First, the possibility that neuroimaging in particular on measuring the effective- ness of advertising campaigns. The general will become cheaper and faster than other marketing methods; and second, the approach has been to show participants a hope that neuroimaging will provide marketers with information that is not product advertisement, either in the form obtainable through conventional marketing methods. Although neuroimaging is of a print advertisement or commercial, and unlikely to be cheaper than other tools in the near future, there is growing evidence measure the brain’s response in the form of a that it may provide hidden information about the consumer experience. The most blood oxygenation level-dependent (BOLD) measurement, which is taken as a proxy for promising application of neuroimaging methods to marketing may come before a neural activation. product is even released — when it is just an idea being developed.
