Post passionnant, très documenté, avec plein de liens très pertinents…Allez, pour vous allécher:

Difference # 1: Brains are analogue; computers are digital […]
Difference # 2: The brain uses content-addressable memory […]
Difference # 3: The brain is a massively parallel machine; computers are modular and serial […]
Difference # 4: Processing speed is not fixed in the brain; there is no system clock […]recent evidence suggests that time-keeping in the brain bears more similarity to ripples on a pond than to a standard digital clock.
Difference # 5 - Short-term memory is not like RAM […]
Difference # 6: No hardware/software distinction can be made with respect to the brain or mind […] the mind emerges directly from the brain, and changes in the mind are always accompanied by changes in the brain.
Difference # 7: Synapses are far more complex than electrical logic gates […] it is therefore profoundly wrong to think that neurons function merely as transistors.
Difference #8: Unlike computers, processing and memory are performed by the same components in the brain  […] retrieval from memory always slightly alters those memories […]
Difference # 9: The brain is a self-organizing system […]
Difference # 10: Brains have bodies […] the brain is "offloading" its memory requirements to the environment in which it exists: why bother remembering the location of objects when a quick glance will suffice? […] we are only beginning to understand the importance of embodiment in information processing.
Bonus Difference: The brain is much, much bigger than any [current] computer […]Because the brain is nonlinear, and because it is so much larger than all current computers, it seems likely that it functions in a completely different fashion. (See here for more on this.) The brain-computer metaphor obscures this important, though perhaps obvious, difference in raw computational power.

C’est superbe…
