Older brain 'too full' for new memories

Age-related learning difficulties could be attributed to the fact that we simply run out of memory space.

Neuroscientists at the Medical College of Georgia conducted research which suggested that the brain of an older person is just as capable of creating strong synaptic connections as a younger person. Instead, the problems with memory as we age are more to do with our inability to weaken existing connections to free up the capacity for new ones.

"What our study suggests is that itís not just the strengthening of connections, but the weakening of the other sets of connections that creates a holistic pattern of synaptic connectivity that is important for long-term memory formation," said study author Dr. Joe Z. Tsien.

"Learning becomes more difficult as we age not because we have trouble absorbing new information, but because we fail to forget the old stuff, researchers say."

Probably too much flouride accumulation and artificial sugars wrecking people's brains over time. Einstein had the brain of a young man when he died, so, it is possible to not have cognitive decline in age. Too many memories is crap, let's try to find the actual root cause.

i don't buy it nor believe it You don't buy or believe what -- that our brain fills up or that the decline with age has other causes or that our brain doesn't decline with age?

One of Scientist Rupert Sheldrake's theories concerning memories is that the brain does not store memories, but simply "streams" them so to speak, and that they are actually part of a higher, possible spiritual construct.

I was reading something a few days ago stating that our actual DNA can hold the equivalent of huuuge sums of data. I've always found the whole sci-fi "ancestral memories" encoded into DNA theories pretty interesing.

After all, there is no real proof supporting that memories are even stored in the brain in the first place. Um it seems to me that the fact that brain injuries often interfere with memory and that disease processes like Alzheimer's Disease destroy memory indicates that the assertion that there is no proof supporting that memories are stored in the brain is false.

Um it seems to me that the fact that brain injuries often interfere with memory and that disease processes like Alzheimer's Disease destroy memory indicates that the assertion that there is no proof supporting that memories are stored in the brain is false. The question actually is whether or not the memory itself is being destroyed, or whether it's the brain's processes that allow the retrieval of memory to be destroyed. There have been many many cases with Alzheimer's patients where they're able to retrieve some old memories for a short time, (sometimes from a trigger object) despite that th... [More]

You are really stretching things to hold onto what seems to me a vain wish. The evidence is plain enough.

You are really stretching things to hold onto what seems to me a vain wish. The evidence is plain enough. The same could also be said to your statements my friend. Your's just happen to be the much more popular belief.

Age-related learning difficulties could be attributed to the fact that we simply run out of memory space. Which is why an external or implanted memory like chip will become a reality in time. ( it already is in existence but not used because ppl are of course afraid of everything, until they notice they'll be using their superiority if they don't evolve with the world).
