| Outline of Final Research Achievements |
As an intermediate level approach between AI and neuroscience, behaviors of artificial neural network have been elucidated. However, since functions of the neural network have not been enough elucidated, we are studying the intermediate level function of the neural network focused on signal transmission or communication function. In 25×25 mesh neural network simulation, we have confirmed it is possible to set asynchronous multiplex communication channel such as 9:9. Corresponding to these, we showed we can set communication channels such as 3:n in wet experiments on cultured neuronal networks. That is, several receiving neurons (group) away from the stimulated neurons (group) could classify/recognize what kind of stimulation was added based on the arrived spike waves. Both of the simulation in artificial neural networks and the experiment in cultured neuronal networks support the multiplex communication scheme in the brain.

脳神経回路について，マクロ的視点からは，AIや深層学習の研究が進んできた．ミクロ的視点からは，神経自体の特性や動作，また中間レベルの神経回路網の特性や振る舞いについてもよく研究されてきた．しかしながら神経回路網の機能については十分研究されていない．本研究は，情報伝達・通信の視点から，シミュレーションと，培養神経回路の対応を取りつつ，神経回路網の機能について研究を行ってきたものである．
その結果，神経回路網では空間的多重通信が行われているであろうことが結論された．これはシミュレーションと培養神経における実験の両面から，神経回路網内の多重通信原理を指摘・解明した最初の研究である．
