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.

Sumantra Chattarji, professor of neurobiology at the National Centre for Biological Sciences (NCBS), Bengaluru, says, “Even a month of social interactions, playtime, exercise, and sensory stimulation can make a two-month-old rat a better learner.” Other studies by Chattarji and his team of researchers have found that if these young rats are stressed for ten days, they lose those connections in the hippocampus.
