During our everyday life we are usually bombarded with different sensory perceptions of high ecological relevance. Especially during food consumption we regularly perceive a combination of stimuli from different sensory modalities rather than a pure unimodal stimulus. Stimulation through multiple sensory channels enables a faster reaction to those stimuli and thereby sharpens the perception of our surrounding. The human brain and its outstanding ability to merge input from various sensory systems and to create a unique percept is a central mediator of cross- and multimodal sensory integration processes.  The major aim of our research is to explore the influence of cross- or multimodal sensory integration using congruent and incongruent combinations of olfactory, auditory, and visual stimuli on human behavior, especially sensitivity and hedonic ratings. Further, we are interested in the neuronal processes mediating cross- and multisensory integration. Implications and possible applications of this research will be discussed.
