This paper explains the concept of neuromarketing and describes the connection of this new branch of marketing with other industries and sciences. Neuromarketing is a combination of psychology, neuroscience and economy and which aims to study people's emotional reacitons toward the product in order to adjust it as much as possible. The study of emotinoal reactions is carried out through various methods such as electroencephalogtam, functional magnetic resonance, galvanic skin response and monitoring of eye movements. The role of neuromarketing through five human senses (sight, hearing, smell, taste and touch) is observed. Various examples are presented for better understanding of the topic. Although a few people find neuromarketing unethical because it intrudes too much in a person’s privacy and subconscious, most people think it’s a very good way to make a good profit. It also describes a person’s buying process, the stages a person goes through while deciding which product to choose. The influence and phenomenon of subliminal advertising accompanied by examples and images is described. A survey was conducted among 60 respondents. The aim of the online survey was to see how much consumers are aware of marketing manipulation, and if so, whether they are susceptible to its influence.
