C56743 Cortical evoked potential auditory intensity value CorEVAudIntVal The value of the auditory intensity used to help find and record the evoked potential. The value of the auditory intensity used to help find and record the evoked potential. Auditory - Intensity Numeric Values

40, 50, 60, 70 dB above sensation level (dB SL) are recommended, or above the normal hearing level (dB nHL) if there is a hearing loss. The different stimulus intensities should be administered in a randomized or pseudo-randomized order, with the intensity not being the lowest or the highest. Because of potential harm to the inner ear, the International Bureau for Audiophonology recommends to exclude subjects with an average hearing loss of 20 dB.

C55774 Imaging headache relation time type ImagHeadacheRelTimeTyp The type of timing of the imaging in relation to headache. The type of timing of the imaging in relation to headache. Timing of recordings Inter-Ictal;Ictal;Peri-Ictal Inter-Ictal;Ictal;Peri-Ictal Alphanumeric

Since cortical EPs may undergo drastic changes just before, during and after a headache attack, it is crucial to mention the timing of recordings in relation to the headache.

The precise time windows for peri-ictal and inter-ictal vary with headache type. For episodic migraine, an interval of at least 72h from the last and before the next attack is generally accepted for "inter-ictal". In migraine with aura, it must be specified if the recordings are performed during the aura, during the headache or during the co-existence of both.

C56733 Cortical evoked potential spatial frequency CorEVSpaFreq The spatial frequency for patterns related to cortical evoked potentials. The spatial frequency for patterns related to cortical evoked potentials. Visual - Spatial frequency Numeric Values

Visual angle subtended by pattern elements in minutes of arc, 1?8` recommended.

To calcuate: a = arctan(W/2D)x120, where a is the visual angle in minutes of arc, W the width of the checks in millimeters and D is the distance of the pattern from the corneal surface in millimeters, or cycles per degree (30/a for bars, 43.2/a for checks).
