Scientists find brain cells that keep track of time with extreme precision
- coffeemug 17y agoI wonder what indexing method the brain uses to index all the events by time. I wouldn't be surprised if binary search trees were somehow involved...
- jacquesm 17y agoThat's a good question. To me the closest thing I can get to describing it is onion rings. You remember one thing, and then you remember something that came before that, and so on. Try to remember the first time you met someone that you know well. It's sort of like a small movie with moments played backwards until that person wasn't in my life, then a bit of jiggling around the 'focal' point, and then some really hard thinking to try to pin it down, pulling in all kinds of auxiliary data to make the final determination.
- nopassrecover 17y agoYou mean a linked list with events at similar times grouped at each node?
- Daniel_Newby 17y agoA process resembling this has actually been measured. Scientists wired electrodes into the brain of a rat, and ran it through a physical activity while recording nerve signals. They left the recorders going afterwards and accidentally noticed that the same signal patterns were being replayed in reverse order.
- philf 17y agoDo you have a link to this research? I'd be interested to read more about it.
- jeromec 17y agoDo you know where I might read more about this? Do you remember what they were studying?
- Daniel_Newby 17y agoHere is a decent article about the research: http://www.bioedonline.org/news/news.cfm?art=2325 http://www.bioedonline.org/news/news.cfm?art=2325
