How do you add the "Keywords:" string in an article header??
Thanks!

Has anyone converted human memory capacity into bits and bytes?
That is to say, is there an equivalent of megabytes to an average
human being's brain capacity?

This is not a simple issue. No one has conclusively demonstrated a limit
to the long term storage capacity of the human brain ("you learn something
new every day!"). I have heard one estimate that the information processing
capacity of a single neuron approaches that of a Cray-1, and there are
10^12 neurons in the human brain...gam@proper.UUCP (Gordon Moffett) (06/13/84)

In "The Dragons of Eden" (pg 42-43), Carl Sagan arrives at a figure of: 10 trillion to 100 trillion bits, which is 1.25 million to 12.5 million megabytes, or 1.25 to 12.5 gigabytes. (... assuming 8-bit bytes).

-------- I believe there are aprroximately 10 to the 9th neurons in a human brain, if that's of any help. Add in the glial cells (there is some debate about their function) and it comes to 10 to the 10th. Bob Binstock

A correction to my previous article on this subject. It has been
pointed out to me that 1 million megabytes does not a gigabyte make.
Thus, the brain may be presumed to have ~1000 gigabytes of memory,
rather than ~1 gigabyte.
My apologies for the error.
