“…Krbot Skorić et al (2014) examined the effect of three aromas using the EEG in Croatia on a sample of 16 participants. Konagai et al (2002) investigated the effect of soybeans aroma heated to various temperatures on EEG, where 14 healthy women aged 21-26 years were tested. EEG waves from 19 electrode sites were recorded, and the power spectrum of the alpha activity using the Fast Fourier Transform (FFT) analysis at each site was then calculated (Nussbaumer, 1981).…”

brain and help in deciding on the next purchase. In this way, the senses evoke emotions or feelings that indirectly decide on the selection or purchase of the product (Srivastava and Singh, 2011).The impact of sensory marketing on the senses can be subtle, which is why consumers do not perceive them as a marketing message and do not react with the usual resistance as in the case of advertising and similar promotions. For example, Hershey's has long realised that the pleasure that people get when unwrapping the chocolate turns an ordinary sweet into a special experience. Another example is Olay Regenerist thermal skin products, designed to generate heat when applied (in spite of the fact that heat is not needed for them to be working), signalling in such a way that they are actually working. Car manufacturers have also not neglected the senses, and the 2014 BMW M5 emitted and amplified the engine sounds through the car's sound system, even when the system was switched off. The goal was to improve the sporty feel of this car (HBR, 2015).The main goal of sensory marketing is therefore to use the consumer sensory perception, in order to evoke a positive experience with the emotional connection to selected factors, such as the point of sale, brand, product, or service (Nadányiová, 2017). Marketers are trying to use various information encoded by all senses to communicate with their potential target customers (Nghiêm-Phú, 2017).Senses can be understood as physical means that allow to see, smell, hear, taste, and touch. For all living beings, information is gathered about the outside world as well as inside within their body through their senses, so these become extremely important. Our five main sense organs include the eyes, nose, ears, tongue, and skin (Srivastava and Singh, 2011).According to Hussain (2019), we recognise the following elements of sensory marketing based on human senses: ▶ the sense of sight -visual marketing; ▶ the sense of hearing -auditory marketing; ▶ the sense of smell -olfactory marketing; ▶ the sense of touch -tactile marketing; ▶ the sense of taste -gustative marketing.Visual marketing is focused on the use of sight in marketing. Sight is still quite often considered the most important sense in marketing communication. Consumer perception is greatly influenced by general shapes, colours, design, lighting, or aesthetics, especially in the case of specific visual aspects (Kuczamer-Kłopotowska, 2017). Neuroscientists claim that

“…These data revealed that the decrease of alpha 1 activity is highly correlated with comfortable state of subjects [61]. Konagai et al [78] investigated the effect of the aroma of soybeans heated to various temperatures in order to understand the relationship of the amino-carbonyl reaction products upon EEG. These results suggest that the aroma products from amino-carbonyl reaction increase alpha wave activity.…”

Influence of Fragrances on Human Psychophysiological Activity: With Special Reference to Human Electroencephalographic Response

The influence of fragrances such as perfumes and room fresheners on the psychophysiological activities of humans has been known for a long time, and its significance is gradually increasing in the medicinal and cosmetic industries. A fragrance consists of volatile chemicals with a molecular weight of less than 300 Da that humans perceive through the olfactory system. In humans, about 300 active olfactory receptor genes are devoted to detecting thousands of different fragrance molecules through a large family of olfactory receptors of a diverse protein sequence. The sense of smell plays an important role in the physiological effects of mood, stress, and working capacity. Electrophysiological studies have revealed that various fragrances affected spontaneous brain activities and cognitive functions, which are measured by an electroencephalograph (EEG). The EEG is a good temporal measure of responses in the central nervous system and it provides information about the physiological state of the brain both in health and disease. The EEG power spectrum is classified into different frequency bands such as delta (0.5–4 Hz), theta (4–8 Hz), alpha (8–13 Hz), beta (13–30 Hz) and gamma (30–50 Hz), and each band is correlated with different features of brain states. A quantitative EEG uses computer software to provide the topographic mapping of the brain activity in frontal, temporal, parietal and occipital brain regions. It is well known that decreases of alpha and beta activities and increases of delta and theta activities are associated with brain pathology and general cognitive decline. In the last few decades, many scientific studies were conducted to investigate the effect of inhalation of aroma on human brain functions. The studies have suggested a significant role for olfactory stimulation in the alteration of cognition, mood, and social behavior. This review aims to evaluate the available literature regarding the influence of fragrances on the psychophysiological activities of humans with special reference to EEG changes.

“…There are cases where the amount of α wave with higher frequency values increase during olfactory stimulation [7]. However, because of its effect in the human state of mind, the aromas are used in medicine [8], phytotherapy [9], and aromatherapy [10].…”

Smelling odors can induce a physiological or a psychological response. The first one is related to the way action potentials act from the olfactory system to the brain, and the second one is related to the emotional way people react to the odor. The electroencephalographic signals are characterized by different parameters, and some of them are used to analyze the effects of the different scents on human. Many studies revealed that odors can cause changes in those signals, and they have documenting the effects of pleasant and unpleasant odors. The present work demonstrates the effect of six different odors on EEG signals from twelve young healthy non-smoking subjects, five male, and seven female in a small range of ages.IAENG Transactions on Engineering Sciences Downloaded from www.worldscientific.com by UNIVERSITY OF BIRMINGHAM on 08/24/15.
