In a memory retrieval task in which 14 participants, 20-54 years of age, viewed a series of nonemotional images, half of which were immediately followed by electrical stimulation of the participants' amygdala, a brain region involved in prioritizing memories, researchers found that the participants exhibited improved memory in next-day memory recognition tests for the images that were followed by amygdala stimulation, compared with control images, findings with implications for the development of memory enhancement therapies.
