Men ought to know that from the brain, and from the brain only, arise our pleasures, joys, laughter and jests, as well as our sorrows, pains, griefs and tears.

Cognition is nothing but computation …

Mechanical analog computers had their origins in Naval Gunnery in World War I […] mechanical analog computers remained of considerable military importance certainly until well into the 1960s and have only been superseded by digital computing systems in the 1970s.

Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them …

If we liken the nervous currents to electric currents, we can compare the nervous system below the hemispheres to a direct circuit from sense-organ to muscle

Consciousness.
This is the castle keep, the central redoubt, the core essence of true mentality, many will argue, and it has so far escaped any plausible reconstruction in neurocomputational terms.

Complicated mental processes are entirely reducible to such simple activities as the attentive observation of statements previously accepted as true, the perception of structural, purely external, connections among these statements, and the execution of mechanical transformations as prescribed by the rules of inference

You who calculate?… Why not use Brains of Steel which never tire?

Can we transfer information directly from one brain to another? And then link multiple brains into a hive-mind like the Borg? Could acquire new information without having actually to learn it? Experiments on rats seem to suggest that we can transfer memories from one brain to another, even when linking them over the internet.
