Descartes was wrong though, and his philosophies regarding the mind are generally regarded more as inspiring romantic sentiments. The problem is that
he came to his conclusion by self-examination. He couldn't feel or detect his mental processes working individually the way the parts of a machine
do. He considered it whole and indivisible... at least so far as the consciousness ("I") is concerned. The unconscious mind has been speculated and
explored since antiquity - and I'm not sure of Descartes exact views on it.
Regardless, Freud's work pretty much laid the foundation for the formal rejection of Rene's perception of consciousness. Roger Sperry put it to rest
when he discovered that slicing the corpus callosum can literally cleave the consciousness in two. While what we don't understand about the brain
still far outstrips what we do know - the application of fMRI to mapping activity and structure has proven invaluable to unlocking the secrets of our
brains. We can pull images and words directly out of the mind via BCI, or temporarily "knock out" very specific cognitive functions - such as the
ability to match faces with identities - by introducing random noise to specific structures. The human brain really is like a gear-box machine with
over (IIRC) 400 structures responsible - though it's function isn't manifest in teeth, springs, or cogs - but complex and seemingly chaotic
cascading storms of electrical activity. These cognitive "gears" of the mind are responsible for either specific cognitive tasks, or as part of a
redundant chain of multiple regions responsible for separate tasks - yet can be utilized in tandem to produce new and unique purposes.
We're even starting to accurately emulate sections of it on the synaptic level... as well as well into molecular emulation.
... they're just working with the neocortical column of rats for now. At the end of the video, note, that he suggests full human brain emulation in
about 10 years.

Okay, can you tell me then, what do you know, about the sun?
