As a multidisciplinary approach to understanding the complex interrelationship between neuroscience, psychology, and marketing, the area of neuro marketing has emerged. This abstract explores the use of cutting-edge neuroscience methods to learn more about the mental mechanisms that underlie consumer decision-making and their reactions to various marketing stimuli. Consumers are inundated with a dizzying selection of goods, services, and advertisements in todays market. Businesses looking to improve their tactics must prioritise understanding the elements influencing customer decisions and the mechanics underlying how they react to marketing initiatives. Traditional marketing research techniques, like surveys and focus groups, frequently rely on self-reported data, which can be biased and may not completely identify the underlying forces shaping consumer behaviour. By giving clear insights into brain activity, emotional responses, and attention patterns, neuroscience techniques like functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and eye-tracking offer a fresh perspective. The goal of neuro marketing is to identify the underlying neurological mechanisms that shape customer decisions by observing neural activity in reaction to particular stimuli. This method may be able to close the gap between conscious and unconscious decision-making processes by illuminating the emotional and cognitive triggers that influence consumer behaviour. This paper highlights the key objectives of the study , Investigating the neurological correlates of consumer behaviour by using neuroimaging methods to look at how various marketing stimuli, such ads, product packaging, and brand logos, influence the activation of brain circuits related to emotion, memory, and reward. Discovering Subconscious Influences: Investigating brain responses that take place before people are cognitively aware of their preferences or choices in order to better understand the significance of subconscious cues in consumer decision-making. Developing more effective ads and custom experiences that connect with customers on a deeper level requires translating neuroscientific research into insights that marketers can use immediately. Addressing privacy issues and the responsible use of neurological data, as well as the ethical implications of applying neuroscience techniques in consumer research. This paper is an attempt to analyse the impact of correlation between neuro marketing and consumer behaviour.
