| Outline of Final Research Achievements |
The distribution of odor filaments in a fluid is ever-changing. How animals read out such instantaneously changing signals in the central nervous system and locate an odor source is an enigma of neuroscience. Typical nocturnal animals, cockroaches are able to locate an odor source based solely on antennal input but not on visual cues. We found that axons of sex pheromone-receptive neurons are orderly represented in different regions of the macroglomerulus based on the three-dimensional soma locations. Our intracellular recordings further revealed that a single projection neuron with dendrites throughout in the macroglomerulus exhibits different temporal patterns to odors given from different directions across the longitudinal antenna.
