EEG activity of 10-month-old infants of depressed and non-depressed mothers was compared during stimuli designed to produce happy and sad responses. During a baseline recording and during their happy facial expressions, infants of depressed mothers showed greater relative right frontal EEG asymmetry compared to infants of non-depressed mothers. The greater relative right frontal EEG asymmetry was also noted during a play interaction with their mothers. Infants of depressed mothers also showed more negative and less positive expressions. These findings are discussed in relation to the theory that frontal EEG activity may be a biological marker for symptoms associated with depression.
