The most complex structure we know of is not some vast galaxy or even a human artifact.It lies between our ears: the human brain.(1)_______________________.But there is still a long way to go.For the new century, there is an amazing new tool called Functional Magnetic Resonance Imaging.Using an FMRI scanner, researchers can watch what happens inside your brain while you think.They can make a map of our brain, placing all our mental functions.(2)_______________________.But when they have completed this amazing map,will they have solved the mysteries of the mind?Some scientists and philosophers think that an understanding of human consciousness is just around the corner.If they are right and consciousness is just an aspect of brain function,then (3)_______________________.However, it may not be so straightforward.Brain mapping may reveal the brain area involved in,for example, sensing the color red-but will it reveal the experience of redness?That is subjective and it may take a new kind of science in the new century before that is understood.
we already know a lot about how it works by studying how things go wrong after injury as well as studying how happy humans behave
they can see areas that respond when we are happy and sad. or when we see particular colour , shape or sound
a new generation of computers with the network of the circuits similer to that of our own brains might also be in doubt with consciousness
