Artifact, in the context of EEG, refers to noisy electrical signals that can distort the readings of brain activity. These artifacts can arise from various sources, such as muscle movements, electrical interferences from nearby equipment, or issues with the electrodes themselves. They are not part of the actual brain wave activity and can significantly impact the interpretation of the EEG data by corrupting the signals that represent true neuronal activity.

Understanding artifact is crucial in EEG analysis because accurate interpretation of brain activity hinges on distinguishing between genuine electrical brain signals and these extraneous distortions. By identifying and minimizing artifacts, technicians can improve the reliability of EEG readings and enhance the quality of neurological assessments. This highlights the importance of recognizing and addressing artifact during the EEG recording process for accurate clinical evaluation and diagnosis.
