By no means rigorous, an estimate for the number of neurons is around 10^10 [0] with an average number of connections estimated at around 8000 [1].
Call 10^10 \approx 2^40 for convenience, and 8000 \approx 2^13, which gives us a 2^53 entropy estimate, or about a petabyte of information as an estimate of what the human brain can store (discounting more exotic theories of memory stored in DNA or some such).
