| Outline of Final Research Achievements |
In the neural network simulation, can be 9 to 9 communication, moderate fluctuations of nerve properties, was found to contribute to the stabilization of the communication. On the other hand, in cultured neuronal networks, some of the observed spike trains at the electrodes, a significant difference for the differences stimulation point was observed. This indicates that it is possible to two-to-one communication.
Code distribution chart that could be visualized is a part of the spike wave , nerve cells , was found to be only passive propagation medium of the spike in the multiplex communication . The behavior of this spike is, if the sound waves are propagated in the air, even if there are obstacles, equivalent to being able to identify the sound source in the ear only. This is an important finding to deny the assumption of conventional implicit "local circuit - specific route thinking."
