Quote from: Trinoc on June 03, 2012, 06:23:45 AMHasn't this recently been found to be a myth, and that new brain cells do grow in later life? How memories are stored is obviously still largely a mystery, but I think it's pretty much accepted that it is a distributed process so that, for instance, knocking out one particular bunch of cells will not erase my memory of the cat I had as a child while leaving associated memories intact. I think some research also suggests that memories are is a sense rewritten (a bit like some sorts of computer memory) when they are accessed, to the extent that (say) traumatic memories can be partly erased by getting the subject to recall them and then causing a major distraction which prevents the memory from getting written back reliably. This suggests that, at least for memories we recall periodically, these could get copied into new nerve cells, leaving behind any dead cells which formerly formed part of the memory.That's my amateur take on the subject. I'm sure Steve could put me right on a lot of things.

Quote from: Fast Eddie B on June 03, 2012, 01:17:38 PMSteve did seem to imply that our brains may have pressure on them to increase in size due to increased need to process data.
QuoteI think that falls into an easy and obvious trap. Brains would only increase in size if there were a reproductive or survival benefit to that bigger brain.
