| Research Abstract |
Exploring the molecular mechanism underlying emotional memory is important for understanding not only how the brain works, but also how psychiatric disorder such as PTSD occurs. It has been known that expression of genes involved in the formation and maintenance of long-term fear memory is dynamically changed during the processes of emotional memory. In this study to know the contribution of microRNA in the processes of fear memory formation, genome-wide screening of microRNAs whose expression is altered in the amygdala after fear conditioning using microRNA microarray. As a result,13 microRNAs were identified: 3 were increased and 10 were decreased. Investigation of the role of these microRNAs will allow us a better understanding of the new aspects of communication between the synapse and the nucleus underlying the long-term retention of emotional memory.
