My calculation was incorrect. IIRC, a gigabyte is a billion bytes. So at 1 kb per brain cell you would need 15,000 gigabytes of data just to store all the connections between brain cells. If you could compress this data down to 100 bytes per cell through some kind of algorithm, then you'd need 1,500 gigabytes of data to store brain cell connections.

You're assuming that the "connections" between braincells are predefined. They're not.
