Resting frontal electroencephalographic asymmetry in depression: Inconsistencies suggest the need to identify mediating factors
Two studies of the relationship between depression and resting frontal electroencephalographic (EEG) activity are reported. Although considerable research supports the theory of left and right hemispheric specialization for approach and withdrawal behaviors, only four studies involving clinically de...

Summary: | Two studies of the relationship between depression
and resting frontal electroencephalographic (EEG) activity
are reported. Although considerable research supports the
theory of left and right hemispheric specialization for
approach and withdrawal behaviors, only four studies involving
clinically depressed individuals have been published to
date. Despite methodological similarities with published
research, no significant differences in frontal activation
emerged between depressed and nondepressed participants
with either college students having high Beck Depression
Inventory scores (Study 1) or with individuals diagnosed
with DSM-III-R depression (Study 2). Post hoc analyses
in Study 2 revealed one effect confined to lateral frontal
leads during the first 2 min of EEG data; this finding
was significant in only one of three reference montages.
Results are discussed in light of methodological considerations
and mediating variables such as temperament and coping
styles. |
