Arousal electrical stimuli evoke sudomotor activity related to P300, and skin vasoconstrictor activity related to N140 in humans

• Skin sympathetic nerve activity (SSNA) contained sudomotor and skin vasoconstrictor activities is modulated not only by thermal conditions, but also arousal stimuli. • We elucidated that different components of event-related potentials (ERPs) are related to sudomotor and vasoconstrictor activities...

• Skin sympathetic nerve activity (SSNA) contained sudomotor and skin vasoconstrictor activities is modulated not only by thermal conditions, but also arousal stimuli. • We elucidated that different components of event-related potentials (ERPs) are related to sudomotor and vasoconstrictor activities composing arousal SSNA bursts. • The sudomotor activity in arousal SSNA is related to attention and the skin vasoconstrictor activity is related to the detection of somatosensory events.
