Outline of Final Research Achievements |
Dye injection and genetic labeling of neurons of multiple primary sensory centers revealed that the mushroom body, which plays critical roles in learning and memory, is directly connected with primary visual, olfactory, and gustatory centers in Drosophila melanogaster. Connectivity patterns between the mushroom body and primary sensory centers suggest that each mushroom body calyx can be divided into four subregions and each mushroom body lobe processes information on different combinations of multiple sensory modalities. This finding provides a novel focus of research by Drosophila genetics for perception of the external world by integrating multisensory signals.
