Therefore, much more research is needed to make concrete conclusions about life recall, the researchers cautioned. Moreover, there is no way to know if the man was actually seeing, or perceiving, his past memories or if he was just in a dream-like state brought on by his failing nervous system. This could have meant his brain activity during death was different from that of someone without epilepsy. The dying man was elderly and had epilepsy, which is known to alter gamma wave activity. Therefore, the researchers speculate that life recall may be a universal experience shared by a majority of mammal dying brains, although there is minimal evidence to back this up.īut the researchers warned that it would be premature to conclusively state that life recall is a real phenomenon. But there has been limited research to explain what the phenomenon involves. "Through generating oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences,"Zemmar said in the statement.Įxperiments in rats have shown that the rodents also experience similar levels of gamma oscillations around the time of death, according to the statement. The idea that life flashes in front of a person has featured in countless works of literature and film.
