Is there a finite amount of brain capacity as measured like a computer, giga / tera bites?

Asked by kelly (1918points) January 28th, 2012

discussion about Sen. Mark Kirk’s stroke (at 52!!!) and that surgeons had to remove some small pieces of dead brain tissue. So was his brain’s “memory” capacity diminished?

The other parts of the brain can pick up the slack. But the older the longer and not as developed will the other side be able to pick up the slack. There is indeed a brain capacity.

According to this article

2.5 petabytes/a million gigabytes

Here’s my two cents though. However like stellar evolution and like how we came to be, the brain is constantly evolving. And like the universe, I believe the brains capacity is expanding, rapidly.

This is interesting.

If the “memory” was part of the brain that was removed, then the memory should be removed as well. How does it follow that “other parts of the brain” could “pick up the slack” on removed memory unless memory isn’t part of the brain at all, but instead a separate non physical thought phenomenon that the brain simply accesses?

@RealEyesRealizeRealLies Well he asked about the capacity, obviously if the part of the brain that stored a certain memory was gone… then yeah.

Memories aren’t stored like data on a hard disc. Memories are created by linking brain cells and there is no limit to how many links there can be. It isn’t infinite but it isn’t limited either. For example look at people with hyperthymesia

Some capacity is lost as a result of loss of brain tissue but it’s not a linear relationship as it would be with a computer. Different areas of the brain tend to be specialized as to their purposes, thus some areas such as the parietal lobes deal with processing and storage of spatial information, while other areas such as the occipital lobe process visual information. In practical terms, patients recovering from brain surgery might have difficulty speaking, coding new memories, remembering faces, remembering specific words, or other such limitations. There are names for each such known syndrome such as prosopagnosia, the inability to remember faces.
