Erase Fear Memories
Did you know studies at Uppsala University have shown that it is possible to erase a fear memory. When you experience a fearful event, a long-lasting memory is created by the process of consolidation (based on the formation of proteins). According to Thomas Ågren, a doctoral candidate at the Department of Psychology and co-author of the study, when participants had the reconsolidation process interrupted, the fearful memory was rendered neutral and no longer incited fear. Using a fMRI scanner, the researchers were able to show that the traces of that memory also disappeared from the amygdala, a part of the brain that normally stores fearful memories.
