A new rodent study shows that newborn neurons destabilize established connections among existing brain cells in the hippocampus, a part of the brain involved in learning and memory. Clearing old memories from the hippocampus makes way for new learning....Other researchers had proposed the idea that neurogenesis, the birth of new neurons, could disrupt existing memories, but the Cell paper is the first to show evidence supporting the idea, says Paul Frankland, a neuroscientist at the Hospital for Sick Children in Toronto....Scientists have known that memories first form in the hippocampus and are later transferred to long-term storage in other parts of the brain. For some amount of time the memory resides both in the hippocampus and elsewhere in the brain. What’s not been known is how, after a few months or years, the memory is gradually cleared from the hippocampus.
I hope this article has given you information that you had not known before. I thought this information was very interesting. I hope you did too.
Until Next Time!

Wow that's very interesting. I would like to know how often your memory is cleared. That could explain a lot!!!!
ReplyDeleteGreat topic, Lauren. This mind/brain stuff is incredibly fascinating to me, and definitely relevant to what we're discussing both in class and on this blog. I do, however, have the following concerns:
ReplyDelete1) Did you actually read this article? If so, did you understand it? The reason I ask is that the article had nothing to do with newborns. The term "newborn" is being used to describe newly formed neurons in the brain...those neurons which allow for new learning to happen. In the future, your posts will be a lot more meaningful if you actually understand what it is you read.
2) The quote that you picked out is perfect. Good job. Besides the quote, though, I would like to see a more thorough summary of the article in your own words.
3) Once again, you have neglected to identify key vocabulary.
