Illustration of auditory stimulus sequence of the brain vital sign framework. Blocks of five tones and two words repeated 60 times for a total scan time of about 5 min. Words represent prime-target pairs, containing both semantic congruent (pink–orange) and incongruent (pink–blue) pairs. Tones (standard = green and deviant = black) elicit sensory (N100) and attention (P300) measures
