The phrase "artifact procedure" is correct and usable in written English.
It can be used in contexts related to processes or methods involving artifacts, often in fields like archaeology, software development, or project management.
Example: "The artifact procedure for analyzing historical items requires careful documentation and preservation techniques."
Alternatives: "artifact process" or "artifact methodology".
To rule out that EEG results could be of artifactual origin (note the use of a TMS-compatible EEG system [ 23] and artifact removal procedures; see Experimental Procedures), we also performed control TMS-EEG recordings in a phantom head using the same TMS, EEG, and postprocessing parameters as in the volunteers.
These segments were submitted to a multivariate semi-automatized artifact detection procedure designed for multi-channel electrophysiology [30].
This artifact rejection procedure ensured that no systematic eye-movements over 0.3° were included in the data.
A semi-automatic artifact removal procedure was applied to these epochs.
The artifact detection procedure of the Somnolyzer24x7 was applied for detecting eye, muscle, sweat and EEG amplitude related artifacts.
The artifact detection procedure of the Somnolyzer 24 × 7 was applied for detecting eye, muscle, sweat and EEG amplitude related artifacts.
In the same way as in the case of the R&K model, the C3-M2 (or alternative C4-M1) EEG channel and the same artifact detection procedure were used.
When applying an artifact rejection procedure after the recording, care should be exercised to assure that clinically important aspects of the waveform are not being modified.
An artifact removal procedure was applied to the continuous data based on independent components analysis (ICA), implemented using EEGLab (Delorme and Makeig 2004).
Using a semiautomatic artifact rejection procedure, we excluded the "bad" epochs in which the absolute voltage difference exceeded 50 μV between 2 neighboring sampling points or the amplitude was outside +100 or −100 μV.
Because the VEOG was not available for all children with DS and to be consistent across participant groups, the continuously recorded EEG on Fp1 was used to deal with eye-blink artifacts, using the 'Ocular artifact reduction' procedure offered in SCAN 4.3.
