Researchers have discovered that memories made under such conditions - or under the effects of drugs or alcohol - tend to only be recalled when a person is back in that state again: something known as state-based learning. By putting mice under the influence of a drug called gaboxadol, a team of scientists at Northwestern University in Illinois have made an important step forward in understanding the molecular processes that underpin the formation of suppressed memories, which could one day be helpful for treating patients suffering from anxiety, PTSD and other conditions. Kat Arney spoke to Jelena Radulovic, who led the team, to find out more...
