Brand equity refers to the economic value that a brand has in the minds of consumers based on trust and perception. This intangible measure can manifest itself in various aspects such as brand awareness, brand loyalty, brand associations and perceived quality. The strength of brand equity can have a significant impact on market success, including pricing, brand image and the company's ability to successfully bring new products to market.

Brand equity is not usually addressed directly in neuromarketing, as it is a construct based on a variety of factors that go beyond the immediate impact of marketing activities. However, neuromarketing-based techniques can be used to understand the elements that contribute to the formation of brand equity. For example, brain research can shed light on how positive emotions and memories of a brand are anchored in the minds of consumers, and how these connections in the brain can lead to people being willing to pay more for a product from a particular brand.

The perception of a brand is not only the result of rational considerations, but is also strongly influenced by emotions, cultural contexts and personal experiences. Neuromarketing methods such as functional magnetic resonance imaging (fMRI) or eye-tracking can be used to measure consumers' unconscious reactions to brand stimuli. These insights can then be used to identify and reinforce the aspects of a brand that generate the highest emotional resonance, thus indirectly increasing brand equity.
