| Outline of Final Research Achievements |
To study how the neural circuits that underlie short-term memory operate, we focused on rich genetic tools available in Drosophila melanogaster and developed a novel experimental system. Using this system, we found that flies remember the position of a visual object for several seconds and use this memory for flight orientation. By recording the neural activity while a fly was performing a short-term memory task, we revealed that neurons in the brain region called bulb carry signals related to visual stimuli, turn direction, and short-term memory.
