The chapter reviews key aspects of the current understanding of the neural substrates for cognitive-emotional interactions in prefrontal cortex based on human functional MRI studies. It is shown that cognitive-emotional interactions assume diverse forms and are not limited to mutual suppression. An emerging theme is that lateral prefrontal cortex is a focal point for cognitive-emotional interactions, which have been observed across a wide range of cognitive tasks. Importantly, whether responses in lateral prefrontal cortex (including dorsal-lateral PFC) increase or decrease in the face of emotional manipulations varies across contexts. As argued, the direction itself (increases vs. decreases) is not diagnostic with respect to the functional nature of the interaction, for example, whether increased activation signifies more or less efficient engagement of prefrontal cortex.
