Experiments in rats show some bad memories can be forgotten

It is believed that exaggerated response to bad memories is similar for all negative memories. A team of Indian scientists, namely, Mohammed Mostafizur Rahman, Ashutosh Shukla and Sumantra Chattarji from the National Centre for Biological Sciences (NCBS) and Institute for Stem Cell Biology and Regenerative Medicine (inSTEM) have shown that exaggerated response and difficulty to get rid of bad memories could depend on whether the bad memory was formed before or after a stressful event.
