The HED standard schema is a hierarchically-organized vocabulary for annotating events and experimental structure. HED annotations consist of comma-separated tags drawn from this vocabulary. This vocabulary can be augmented by terms drawn from specialized library schema.
Each term in this vocabulary has a human-readable description and may include additional attributes that give additional properties or that specify how tools should treat the tag during analysis. The meaning of these attributes is described in the Additional schema properties section.

ECG-artifact
An electrical artifact from the far-field potential from pulsation of the heart, time locked to QRS complex.
hedId
HED_0012496
EMG-artifact
Artifact from muscle activity and myogenic potentials at the measurements site. In EEG, myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (e.g. clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.
hedId
HED_0012497
Eye-artifact
Ocular movements and blinks can result in artifacts in different types of data. In electrophysiology data, these can result transients and offsets the signal.
hedId
HED_0012498
Eye-blink-artifact
Artifact from eye blinking. In EEG, Fp1/Fp2 electrodes become electro-positive with eye closure because the cornea is positively charged causing a negative deflection in Fp1/Fp2. If the eye blink is unilateral, consider prosthetic eye.
hedId
HED_0012499
Eye-movement-artifact
Eye movements can cause artifacts on recordings. The charge of the eye can especially cause artifacts in electrophysiology data.
hedId
HED_0012500
Horizontal-eye-movement-artifact
Artifact from moving eyes left-to-right and right-to-left. In EEG, there is an upward deflection in the Fp2-F8 derivation, when the eyes move to the right side. In this case F8 becomes more positive and therefore. When the eyes move to the left, F7 becomes more positive and there is an upward deflection in the Fp1-F7 derivation.
hedId
HED_0012501
Nystagmus-artifact
Artifact from nystagmus (a vision condition in which the eyes make repetitive, uncontrolled movements).
hedId
HED_0012502
Slow-eye-movement-artifact
Artifacts originating from slow, rolling eye-movements, seen during drowsiness.
hedId
HED_0012503
Vertical-eye-movement-artifact
Artifact from moving eyes up and down. In EEG, this causes positive potentials (50-100 micro V) with bi-frontal distribution, maximum at Fp1 and Fp2, when the eyeball rotates upward. The downward rotation of the eyeball is associated with the negative deflection. The time course of the deflections is similar to the time course of the eyeball movement.
hedId
HED_0012504
Movement-artifact

HED_0012509
Sweat-artifact
Artifact from sweating. In EEG, this is a low amplitude undulating waveform that is usually greater than 2 seconds and may appear to be an unstable baseline.
hedId
HED_0012510
Tongue-movement-artifact
Artifact from tongue movement (Glossokinetic). The tongue functions as a dipole, with the tip negative with respect to the base. In EEG, the artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.
hedId
HED_0012511
Nonbiological-artifact
A data artifact arising from a non-biological source.
