From: Developmental changes of the contingent negative variation in migraine and healthy children
Course of habituation of the iCNV determined at T1 (1998) and T2 (2006) in healthy subjects and migraine patients (with remission, improved or worsened headaches). Amplitudes in eight blocks of recordings are given as mean and standard error. Regression lines are supported by equations y = A(z) x + B(up) where A is a mean of regression coefficient and z its standard deviation; B an intercept and up its standard deviation
