Figure 1 Can people suppress emotional memories and, if so, how do they do it? By examining activity in brain regions that support memory processing, Depue et al. (p. 215) provide evidence that an active memory suppression mechanism really exists. First, one portion of prefrontal cortex suppresses regions involved in the sensory aspects of memory. Second, a different part of prefrontal cortex suppresses brain regions that support memory processes as well as those brain areas that support emotional associations with memory. The results may help to explain the lack of control exhibited in a variety of psychiatric disorders, over emotional memories and thoughts, and extend our understanding of brain mechanisms that control their formation.
