Abstract
Research has shown that brain functions are realized by simultaneous oscillations in various frequency bands. In addition
to examining oscillations in pre-specified bands, interactions and relations between the different frequency bandwidths is
another important aspect that needs to be considered in unraveling the workings of the human brain and its functions. In this
review we provide evidence that studying interdependencies between brain oscillations may be a valuable approach to study
the electrophysiological processes associated with motivation and emotional states. Studies will be presented showing that
amplitude-amplitude coupling between delta-alpha and delta-beta oscillations varies as a function of state anxiety and approach-avoidance-related
motivation, and that changes in the association between delta-beta oscillations can be observed following successful psychotherapy.
Together these studies suggest that cross-frequency coupling of brain oscillations may contribute to expanding our understanding
of the neural processes underlying motivation and emotion.
