(2019-10월)
The modern adult human brain weighs only 1/50 of the
total body weight but uses up to 1/5 of the total
energy needs. The brain's running costs are about eight
to ten times as high, per unit mass, as ①those of the
body's muscles. And around 3/4 of that energy is
expended on neurons, the ②specialized brain cells that
communicate in vast networks to generate our thoughts
and behaviours. An individual neuron ③sends a signal
in the brain uses as much energy as a leg muscle cell
running a marathon. Of course, we use more energy
overall when we are running, but we are not always on
the move, whereas our brains never switch off. Even
though the brain is metabolically greedy, it still
outclasses any desktop computer both in terms of the
calculations it can perform and the efficiency ④at which
it does this. We may have built computers that can
beat our top Grand Master □□□□□, □□□□□. □□□□□ as a □□□□□.
