As well as all other branches of trade, so retail trade itself undergoes various changes and trends with regard to the development of information and communication technologies which affect not only traders themselves but also their customers. It is the retail store environment itself which is one of the decisive aspects of purchase because more than 70% of consumer decisions take place directly at the point of sale. It is the last place which can reverse the purchasing decision. A final customers´ decision is influenced not only by price, quality but also by in-store communication and visual aspects of each store. That is the reason for continuous gathering of feedback on the effectiveness and efficiency of these means of communication in real environment. Besides traditional research techniques there are situations which require the involvement of relatively new research methods. Thanks to the innovative interdisciplinary approach with the use of neuromarketing, it is possible to create effective marketing strategies and thus stimulate the customer attention and emotions. By these emotions, it is possible to achieve better motivation toward purchase and an increase in the number of sales and subsequent raise in income. The paper deals with a complex, interdisciplinary examination of the in-store communication impact on customer visual attention, emotions and related spatial behaviour of customers in grocery stores. Research integrates measurements of mobile eye camera (Eye tracker), mobile electroencephalograph (EEG), face reading technology (FA) and internal position system in real conditions of retail store. The purpose of this research is to recognise the attention, emotional response and spatial customer preferences by means of selected in-store communication tools. At the end of the paper we explain how the neuromarketing methods can be used for better understanding of consumer behaviour at the point of sale.

The ability to succeed in a competitive market means to respond flexibly to difficult market demands by setting appropriate price, quality, and not least by creating a favourable environment for cultural, but also attractive shopping at a point of sale. Thanks to the innovative interdisciplinary approach using neuromarketing, we can create effective marketing strategies and thereby stimulate human emotions through which it is possible to achieve an increase in the number of deals, multiply revenue and improve the ability to stimulate a purchase. Commercial spaces are becoming more sophisticated day by day and the results of several surveys of consumer behaviour show that more than half of decisions 50-80% related to purchases are made on the point of sale and 80% are realized on the basis of positive emotions. An emotion is a complex processing of phenomena or situations which is determined by the relationship between their objective characteristics and needs of the subject. The element of lighting in shops also influences positive emotions of consumers being able to increase or decrease the sales. Lighting is the only factor that can be accurately measured and controlled. Accent lighting of a modern shop is largely involved in the overall design and the resultant atmosphere of the shop, playing a crucial role in presenting different kinds of goods. The use of accent lighting can draw the customer's attention to a specific part of retail space and achieve the overall harmonization of the shop. For some goods (fresh unpackaged food) lighting is not only powerful, but also the only marketing tool. The main objective of this paper is to clarify the influence of various types of accent lighting (different colour temperature, intensity) on the brain activity of respondents and their resultant emotional state (arousal / valence). Cortical brain activity was recorded via a wireless 14 channel electroencephalograph. The object of investigation is the impact of accent lighting in the section of fresh food (fruit, vegetables, bread, pastry). In the end of the article we explain how neuroscience can be used for a better understanding of consumer perception of accent lighting in the food market.
