As a fermi estimate, the human brain has on the order of 10^11 neurons, each of which has on the order of 10^4 synapses. If we’re able to compress the information about each synapse—its location, chemical environment, connections, action potentials, etc. - into a kilobyte (10^3 bytes) (wild guess), this gives us 10^18 bytes for a human brain. Or, about 1 exabyte (1000 petabytes).
How many is ‘multiple’? A dozen? A hundred?
