Abstract
Episodic memory allows us to relive the past and adapt to the future. Several factors impact how we store information, of which one is emotion. We experience emotional episodes very vividly as they become part of our personal narratives. While specific details of positive memories may fade with time, negative experiences seem to leave us with a long-lasting mnemonical mark. This evolutionarily conserved phenomenon is accompanied by drawbacks for modern humankind as it increases our susceptibility to mood and anxiety disorders. It is crucial to understand the neural processes that underlie the interaction between memory and emotion and its maladaptive forms. Previous analyses of neural oscillation patterns that characterize mnemonic mechanisms have been successful in predicting memory encoding and retrieval, and the mechanisms that characterize how we respond to emotional input. Yet, our knowledge about the neural mechanisms that drive emotional memory is scarce. The current study focuses on investigating the neural correlates of both encoding and retrieval of events varying in emotional and semantic content. We discovered both subsequent memory effects and retrieval effects presented as typical synchronization and desynchronization patterns that were sensitive to changes in the emotional and semantic content of the learning episode. Our findings complement current theories in the field, while they contrast others, and they bear both clinical and scientific implications.
