Abstract
Awake background electroencephalograms (EEGs) are interpreted by an electroencephalographer (EEGer), and the results of EEG interpretation are described in EEG reports. These reports, which include enough contents so that the time series of raw EEG can be imaged from them, are desired. In this study, a method for constructing an EEG model in consideration of an EEGer's visual interpretation was proposed. First, the values of specific EEG parameters for EEG interpretation items were determined based on EEGer's EEG report, and the model parameters were calculated from the determined EEG parameters by using the relationship between the model parameters and the EEG parameters. The proposed models were constructed for the EEG data of 8 subjects. The time series of constructed models were evaluated by use of the automatic EEG interpretation method, which was previously proposed by us, and it was seen that the results of EEG interpretation for models were almost equal to those for raw EEG.
