artifacts in biosignals

Artifacts in biosignals are unwanted or false signals that can distort or obscure the true physiological data being recorded, such as heart rate or brain activity. They arise from external factors like muscles moving, electrical interference, or poor electrode contact, as well as internal factors like patient movement or breathing. These artifacts can make it difficult for healthcare professionals to accurately interpret the signals. Recognizing and minimizing artifacts is crucial for reliable diagnostics, often involving careful setup, filtering techniques, and signal processing to ensure the data reflects genuine biological activity.
