![]() ![]() They can examine the detailed electrical activity of small numbers of neurons. They have sketched out the broad anatomy of the brain, and realize that individual functions… are mediated by circuitry that crosses anatomical borders. “Neuroscientists know frighteningly little about the brain’s complexity. The challenge is described well by the journal Nature: Where consciousness is located in the brain - that is, the parts and functions that make us “us” - is likewise shrouded in mystery. How does the brain store information? We don’t know. Cassette tapes are analog recordings, and information is stored magnetically. For instance, what is the biological mechanism that encodes memories? On a computer, files are encoded digitally with a series of ones and zeroes, a type of discrete storage. Though we know a lot about the anatomy of the brain, its functions remain largely enigmatic.
