[Eeglablist] P and N values in EEG data

[Humera Sharif]

Hi,

Could anyone please explain what P and N (such as P300/N100 etc.) peaks in
EEG data in response to negative stimuli (Event) indicate? P is a
positive peak, so P in a negative stimulus means 'less disgusting, less
negative, less hated' compared to the N peak. And does the same apply to
the N peak for positive stimuli?

Thanks in advance.

Best regards,
Humera Sharif
