Evoking scenes from science fiction B-movies, (I’m looking at you, Battlefield Earth), scientists at Case Western Reserve University School of Medicine succeeded in implanting rudimentary memories in sections of
puny rat-brains! rat brain tissue.
In their study, the researchers sought to better understand the mechanisms underlying short-term declarative memories such as remembering a phone number or email address someone has just shared.
Using isolated pieces of rodent brain tissue, the researchers demonstrated that they could form a memory of which one of four input pathways was activated. The neural circuits contained within small isolated sections of the brain region called the hippocampus maintained the memory of stimulated input for more than 10 seconds. The information about which pathway was stimulated was evident by the changes in the ongoing activity of brain cells.
The experiment will pave the way for a greater understanding of how short-term memories are formed, according to the article at ScienceDaily.
