Secondary Database Searching & Hidden Markov Model.EEG Games EEG technology has been adapted to the gaming world for both medical and entertainment purposes. This chapter describes how electroencephalography (EEG) and magnetoencephalography (MEG) offer complementary alternatives to typical neuroimaging studies. Electromagnetic Blood Flow Meter and its Advantages There is a better understanding of exactly what signal is measured with EEG, compared to the BOLD (Blood-oxygen-level-dependent) imaging used in fMRI. An EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp.Input Guarding in Biomedical Instrumentation.We also show an example of how an EEG methodology could be used to analyze cultural differences between fruition of video commercials of carbonated beverages in Western and Eastern countries. These information could be unobtainable through common tools used in standard marketing research. We noted that temporal and frequency patterns of brain signals are able to provide possible descriptors conveying information about the cognitive and emotional processes in subjects observing commercial advertisements.

Such information will be related to the memorization and pleasantness related to such stimuli. By presenting data gathered through MEG and high resolution EEG we will show which kind of information it is possible to gather with these methodologies while the persons are watching marketing relevant stimuli. In addition, EEG and MEG technologies have greatly improved their spatial resolution in the last decades with the introduction of advanced signal processing methodologies. An EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp.

The interest for these methodologies relies in their high-temporal resolution as opposed to the investigation of such problem with the functional Magnetic Resonance Imaging (fMRI) methodology, also largely used in the marketing research. Here we present an overview of some published papers of interest for the marketing research employing electroencephalogram (EEG) and magnetoencephalogram (MEG) methods.
