Ryosuke O. Tachibana (Project Associate Professor, Komaba Organization for Educational Excellence, Graduate School of Arts and Sciences, The University of Tokyo）

Dr. Tachibana developed USVSEG, the software we are currently using to analyze rodent ultrasonic vocalizations (USVs). This software has dramatically reduced the time it takes to analyze USVs and improved the accuracy and flexibility of the analysis. Not only is Dr. Tachibana a strong programmer, but he is also a researcher of avian vocalizations, so he has a deep understanding of the mice USVs and our requirements. We are still working on adding functions to the USVSEG. I was keenly aware of the importance of joint research.

Jumpei Matsumoto (Assistant professor, University of Toyama)

We have jointly developed an ultrasonic camera, named USVCAM that can localize the source of vocalizations (identify which individual is the source of vocalizations) when observing multiple mice. The device and software were developed by Dr. Matsumoto, and validated by our laboratory through behavioral analysis before being released. This will allow for more complex analysis in the future.

Masahiro Kato (Representative Director, Katou Acoustics Consultant Office / Part-time Lecturer, Osawa Memorial Institute of Architectural Environmental Engineering, Kanto Gakuin University)

Dr. Kato have had various devices and instruments fabricated, including ultrasonic measurement devices and ultrasonic speakers used in our laboratory. The ultrasonic measuring device can synchronously record video and sound, and the development of a mass-produced USVCAM is underway. Equipment used in this laboratory can be purchased from Katou Acoustics Consultant Office unless there is a shortage of parts.

Hiroyuki Okuno (Professor, Biochemistry and Molecular Biology, Graduate School of Medical and Dental Sciences, Kagoshima University)

Dr. Okuno is providing us AAVs for transfection for optogenetics and fiberphotometry.

Shota Okabe (Visiting researcher, Jichi Medical University)

Dr. Okabe is an expert on ultrasonic vocalizations in rats. We often talk about the functions of ultrasonic vocalizations in rats and mice, their similarities and differences, on a regular basis.
