| Abstract: | A data sampler system is introduced using the signals of the P300 waveforms of event related potentials (ERP), the event related desynchronization (ERD), the event related synchronization (ERS) and the saturation of blood and oxygen of the brain to diagnose the early aged dementia. The relationship between the signals of the events and the aged dementia is discussed, the work principle of the diagnostic system and the hardware plan of the sampler are introduced, and the software structure of the sampler is finally given. |
