Korea Brain Research Institute (KBRI, President Pann Ghill Suh) announced on May 26 that a joint research team, led by Prof. Joung-Hun Kim and Dr. Joo Han Lee at the Pohang University of Science and Technology (POSTECH), Dr. Ja Wook Koo at the KBRI, and Prof. Eric Nestler at the Icahn School of Medicine at Mount Sinai, discovered that dopamine D2 receptors (DRD2s) in cholinergic interneurons (ChINs) play a crucial role in cocaine addiction. The findings were published in Biological Psychiatry, a leading academic journal in the field of psychiatry.

Even among healthy people, a faltering memory is often an expected part of aging -- but it's not inevitable. "Some individuals exhibit remarkable maintenance of memory function throughout late adulthood, whereas others experience significant memory decline. Studying these differences across individuals is critical for understanding the complexities of brain aging, including how to promote resilience and longevity," said Alexandra Trelle, a postdoctoral research fellow at Stanford University. Building on studies that have focused on young populations, Trelle and colleagues are investigating memory recall in healthy, older adults

Parents pass genes along to their offspring which equip them for their future life. In recent years, research has shown that the reality is much more complex and that parents endow much more than just genes. A new study reveals that active epigenetic modifications are also passed from one generation to the next. Human mothers grow babies in their bellies for nine months, and then after giving birth proceed to spend years raising and nurturing their children, teaching them how to perform both basic and advanced survival tasks. Fruit flies, on the other hand, lay eggs that are left to develop on their own.
