Appendix
Low Yield (⬓): This is reported when the amount and/or quality of the acquired data are insufficient to generate an accurate number. This may result from the
presence of one or more artifact sources such as motion, sweating, poor electrode-scalp contact, or interference from nearby electronic equipment.
Questionable Value (❓): Possibly due to low A lpha or Peak Frequency magnitude relativ e to back ground EEG noise.
Excess Synchrony (⧪): A ty pe of artifact which may affect multiple channels equally at the same time. This may be due to improper electrode connections or
env ironmental interference. Excess Sy nchrony can reduce the accuracy of back ground EEG metrics.
Manually Modified A rtifacting (★): Shown next to sessions in which at least one input file has manually modified artifacting.
Sync Blink s: Short for "sy nchronized ey e blink s," this is reported when FP1 or FP2 is greater than or equal to 20 μV. Sy nc Blink s may affect the reported P300
and/or Flank er test depths and latencies at other electrode locations.
P300 Metrics
Physical Reaction Time: The average time of the phy sical response to rare tones, deriv ed from mouse or k ey board input.
Reported as "N/A " if there were less than 15 phy sical responses to rare tones.
A udio P300 Delay and A udio P300 Voltage metrics are deriv ed from Central-Parietal (C-P) locations CZ, C3, C4, PZ, P3, and P4 with sufficient
yield.
For these metrics, "yield" is defined as the number of brain responses to rare tones which contain minimal artifact.
A udio P300 Delay: The fastest C -P latency between 240-499 ms after a rare tone, among locations that are at least 3 μV.
Reported as "N/A " if no C -P location is at least 3 μV, or no C -P location has a y ield of at least 20 rare ev ents.
A udio P300 Voltage: The largest C -P amplitude between 240-499 ms after a rare tone.
Reported as "N/A " if no C -P location has a y ield of at least 20 rare ev ents.
Reported as "< 0 μV" if the v oltage at all C -P locations is less than 0 μV.
Low Yield (⬓) is shown next to v alues for A udio P300 Delay or A udio P300 Voltage if:
Less than 3 C -P locations hav e a y ield of at least 30; OR
40% or more data segments contain excessive Delta artifact at the location from which the metric was deriv ed.
Back ground EEG Metrics
Metrics include CZ Theta/Beta, F3/F4 A lpha, Coherence, Muscle Tension, Peak Frequency. For ey es closed metrics, P300 needs to be run, otherwise
reported as "N/A ".
Low Yield (⬓) is shown next to a back ground EEG metric if:
Less than 30 segments of data are clean or contain minimal artifact; OR
For metrics using Delta or Theta, over 40% of data segments contain excessive Delta artifact.
"N/A " is reported for a back ground EEG metric if:
Less than 20 segments of data are clean or contain minimal artifact; OR
For metrics using Delta or Theta, over 50% of data segments contain excessive Delta artifact.
P300 Topos
A P300 topo is generated for a session if at least 3 C -P locations hav e a y ield of at least 20 rare ev ents. Otherwise, "N/A " is shown.
Black Xs indicate topo locations with a y ield of less than 20 rare ev ents. For graphical interpolation purposes, these locations are also set to 0 μV regardless of
their actual v alues.
A topo location is considered "good" if its y ield is at least 20 rare ev ents, and its v oltage is at least 3 μV.
The warning "No consistent P300" is shown below a topo if:
A t least 2 good locations are less than 350 ms, and at least 2 good locations are greater than 450 ms; OR
Less than 40% of good C -P location pairs are within 75 ms; OR
The C -P location with the largest μV v alue is at 500 ms after a rare ev ent.
