Literature survey: Recording set up for electroencephalography (EEG) acquisition

摘要

Electroencephalogram (EEG) is used to study the activity of human brain using instrument named electroen-cephalograph. The application of EEG is now widened to many fields due to its great temporal resolution and other advantages. To utilize the advantage of EEG, the correct setup need to be done for recording the EEG. This is to ensure the EEG recorded is informative enough to serve the targeting application. In this paper, a literature study has been done to explore parameters of EEG recording used for different application. The parameters are number of channels, sampling rate and recording duration. It was found that for medical applications, the number of channel used ranging from two to 100 channels, sampling rate of 100Hz to 3000Hz, and recording duration from 3000 seconds to 21600 seconds. For BCI and neuromarketing, the number of channels used is from one up to 256 channels, 100Hz to 1000Hz sampling rate, and recording duration from five seconds onwards and some researches used continuous recording.
