| Research Abstract |
We aimed to establish the objective evaluation method of human mental and language disorders in preconscious process in relation to spatial cognitive functions on the basis of neurosynaptic circuit model of bilateral auditory systems.
1. We investigated the relationships among brain evoked activities, brain functions, mental as well as language disorders, and psychotherapeutic agent based on the coordinations between neurotransmitters and modulators.
2. To establish the method of testing and quantifying on mental and kanguage disorders, we developed an online experimental system for mental and language tasks with audiovisual presentation.
3. We completed a program for mapping 3D scalp current densities of multi-channel EEG/MEG temoral data and source modeling.
4. We improved the program for dynamical presentation of 3D mapping.
5. We tried to apply the system to clinical and engineering use for evaluation of mental and language disorders.
