| Outline of Final Research Achievements |
The olfactory information is spatially represented as an “odor map” over the olfactory bulb. It is yet unclear how this map is transferred to the next level. This study aims at dissecting olfactory secondary circuits by focusing on birthdate differences of olfactory bulb neurons. We made transgenic mouse lines in which DNA recombination is induced in a neuronal birthdate-dependent manner. Using the mouse lines, I revealed that olfactory bulb neurons with different birthdates have different projection patterns.
