Based on study results obtained in the past, we have demonstrated that the function to transfer neural signals to the brain, by appropriately reflecting signals in terms of quality and quantity, activates the reconstruction of synaptic circuits in the childhood, after which synaptic circuits are maintained by the molecular mechanism in the adulthood. Regarding the next step, we are interested in the “mechanism for appropriately transferring neural signals to the brain, in terms of quality and quantity,” which is the basis of signal transduction itself. Of course, “the molecular mechanism for the development of synaptic circuits” has merely started to be revealed; therefore, in the future, with these two study objectives, I am looking forward to studying with you at the Hokudai campus where you can enjoy a sense of the seasons. I hope to see students with a sparkle in their eyes come to Hokudai and share time learning and studying together.
