Eclipse – Instructions for Use - US
P1, N1, P2 suprathreshold P300
Awake and quit adults, children
and infants
Eyes open
Attend or ignore conditions
Tone burst, speech vowels or
consonant vowel combinations
1-2 sec
60-80dB peSPL
Tip of nose of averaged reference
(jumped electrodes)
1-30Hz
Pre stimuli -100ms
Post stimuli 700ms or more
50-300
At least 2
P1, N1, P2
P1, N200-250
Reliable components
Baseline to peak amplitude, peak
latency
Use latency window established
using grand mean data
Replicable components
Response 2-3x larger than
amplitude in prestimulus interval
MMN
Awake and quit adults, children
and infants
Eyes open
Ignore conditions
Tone burst, speech vowels or
consonant vowel combinations
0.1-1 sec
50-300ms
Be careful of overlapping
response if analysis time is short
Oddball paradigm
Deviant probability 0.05-0.20
Number of deviants at least 200
60-80dB peSPL
Tip of nose of averaged
reference (jumped electrodes)
1-30Hz
Pre stimuli -50ms or more
Post stimuli 400ms or more
50-300
At least 2, resulting in at least
200 deviants.
Any age, use difference
waveform (response to deviant)
Baseline to peak amplitude, peak
latency
Consider mean MMN amplitude
in response window
Use latency window established
using grand mean data
Replicable components
Response 2-3 times larger than
amplitude in prestimulus interval
