Forgotten memories may be retrievable
Do you remember taking your very first step, or enjoying your second birthday party? Probably not, but that probably won't seem weird to you because we have become conditioned to accept infantile amnesia as a fact of life. However, we are all considerably more concerned by adult amnesia, which is something that over 33 percent of us will experience over the course of our lives. This may be mediated through aging, disease, misadventure, or be imparted by other routes. Our memories – though hard to define or explain to others – help to make us who we are. Experience shapes us, helping us to learn and develop. This is why dementia and amnesia can be so debilitating for those who live with either. The common perception has generally been to equate memories with pages that fill an ever-growing book with the tales each and every one of us pen as we do the walk of life. Once a page is burned, or torn out – we were told – the memories contained within were lost forever. Yet that isn't the case. The real picture is far more positive, according to Assistant Professor in Trinity's School of Biochemistry and Immunology, Tomás Ryan, who delivered the below TEDMED talk on this very topic last year. Professor Ryan's work in memory and the neuro-architecture involved in mice suggests that memories remain intact and seem to be retrievable. Memory loss seems to occur when the access mechanisms fail but there are ways to reboot the system as each 'memory engram'—related to a host of connected cells in the brain—can be stimulated if you know how.
