Amuza team member and product manager for O’Hara Behavioral Testing Solutions, Taylor Clark, travels to Japan to learn more about the applications of O’Hara products from their users.

For over 40 years, O’Hara has been developing and manufacturing equipment for behavioral experiments in Japan. Their products are currently used by over 150 researchers at universities, research institutes, and industrial labs across Japan.

Taylor Clark, Product Manager for O’Hara in the US, traveled to Japan to visit and learn from the researcher’s who have been working with O’Hara products. Her first stop – Tokyo University!

Here’s what she had to say:

First, I had the pleasure of visiting Dr. Masanori Matsuzaki’s laboratory in the Department of Physiology at Tokyo University School of Medicine.

Dr. Matsuzaki’s lab is interested in information processing in the Motor Cortex during motor skills learning. They apply several different techniques including two-photon imaging, optogenetics, and electrophysiology in behaving mice and marmosets to monitor and manipulate neural circuits in Motor Cortex that are involved in the initiation and execution of motor actions.

Currently, Dr. Matsuzaki’s lab is using the TaskForcer in combination with two-photon imaging of mice implanted with cranial windows, in order to monitor calcium dynamics of GCaMP (a genetically encoded calcium indicator) infected neurons in the Motor Cortex during skilled learning.

In speaking with Dr. Telada, assistant professor in Dr. Matsuzaki’s lab about the TaskForcer, here’s what he had to say:
“We needed a behavioral apparatus that would allow us to perform longitudinal imaging of the same neuronal populations over time during learning, which is why we chose to use the TaskForcer.”

“With the TaskForcer, we are able to consistently get precise neural recordings during imaging sessions while the mice perform a manual lever pull task.”

“We have now been using the TaskForcer in combination with a custom made two-photon microscope we built that enables super wide-field imaging. This has allowed us to simultaneously image neurons in both primary and secondary motor cortices during motor skills learning.”
