One of the biggest questions in today's market is what drives consumers to decide on one product instead of another; therefore there is a growing interest in understanding how brain responses influence the decision making process of consumers. Neuromarketing presents itself as one of the main areas of study aimed at achieving this goal, however it is still a new and constantly developing field. This research analysed the studies of neuromarketing applied to consumer behaviour over the last five years through an integrative literature review, identifying how the studies on this subject are being developed. This study concludes that major advances are being made in the area, and that neuromarketing can really help in the understanding of cognitive processes and their influence on decision-making, and it has a better performance when used jointly with traditional marketing techniques.
