The manuscript

The data analyzed in our study is available on this page. The sampling rate of the data was 173.61 Hz. For a more detailed description of the data please refer to the manuscript Please note, however, that the time series have the spectral bandwith of the aquisition system, which is 0.5 Hz to 85 Hz. The application of a low-pass filter of 40 Hz, as described in the manuscript, is regarded as the first step of analysis and therefore not carried out for the downloadable time series.

The Data

For each set (A-E) there is a ZIP-file containing 100 TXT-files. Each TXT-file consists of 4096 samples of one EEG time series in ASCII code.

SET A with Z000.txt - Z100.txt (564 kB)

SET B with O000.txt - O100.txt (611 kB)

SET C with N000.txt - N100.txt (560 kB)

SET D with F000.txt - F100.txt (569kB)

SET E with S000.txt - S100.txt (747kB)



This EPS-file (602kB) shows one exemplary EEG time series for every set. These are the time series Z093, O015, N062, F021, S056.
