Researchers Create Short-term Memories In Rat Brains
An anonymous reader writes "Researchers say they've found a way to store artificial short-term memories in isolated brain tissue. 'This is the first time anyone has found a way to store information over seconds about both temporal sequences and stimulus patterns directly in brain tissue,' says the study's lead. 'This paves the way for future research to identify the specific brain circuits that allow us to form short-term memories.' The peer-reviewed study can be found here (paywalled)."
Yes, they know that the plaques impair brain function by inference, they don't understand how, because no one knows what a memory is. Face it, we know a lot about the physical structure of the brain, but we don't really know how it works. Asserting that we understand the process of memory because we know a few things about a disease linked to memory is false equivalence. It's equally disingenuous to suggest that knowing more about how memories are formed, stored, and accessed would have no practical benefit when trying to understand and treat diseases which affect memory.
