Knowing how the brain remembers one-time events can help scientists design better therapies for diseases such as Alzheimer's in which the ability to form such memories is impared. [...]The hippocampus is the main part of the brain that affects all types of memory. So, if scientists can understand how the hippocampus works, it will make it much easier to understand, and hopefully eventually treat memory affecting diseases.
It is well known that a brain structure called the hippocampus is critical to memory and learning, but many questions exist about how brief experiences trigger the physical changes necessary for memory. In his study, Guzowski set out to learn how neurons in the hippocampus react to single events--particularly in the CA3 region, which is thought to be most critical for single-event memory. [...]
Past studies have shown that turning on Arc is required to convert experiences into long-term memory.

How Brain Remembers Single Events
Many people wonder how certain memories stay vivid in your memory while others fade away. According to Science Daily, many scientists didn't know much about what happened in the brain to make you remember these events, but neuroscientist John Guzowski and his collegues found that a single experience is as effective as repetitive activities in activationg neurons and genes linked to with memory.

It would actually be really useful if we did get the chance to help our memories, even for people with out a memory affecting disease.
ReplyDeleteI don't know if you had moved to eudora yet when this happened, but sometime at the beginning of the year mrs. greenway told us a little bit about how the brain learns and I was really interested in it, so I loved this article.
ReplyDeleteI always wondered why i would remember certain moments that don't even seem to be that important. That's why i read this.
ReplyDeleteGreat post, Kayla. The hippocampus stuff really ties in well to a previous post by Lauren.
ReplyDeleteI went in and played around with the format of your quote a little bit. I hope you don't mind.
Good work...this is exactly what we're looking for here. 25/25
marijuana effects this part of the brain significantly. they say that marijuana completely destroys your ability to remember short term events...just thought i would throw that out there since we were reading about it today in our first hour.
ReplyDeleteThat's really interesting...if they do figure out how to treat those diseases it could hopefully help old people.
