Thinking
Some scientists claim that we humans are the only living things that are conscious (有意识的)-we alone
are aware that we are thinking.
No one knows how consciousness works-it is one of science's last great mysteries.
All your thoughts take place in the cerebrum (大脑皮质), which is at the top of your brain, and different
kinds of thought are linked to different areas, called association areas.
Each half of the cerebrum has four rounded ends called lobes (脑叶)-two at the front (frontal and
temporal lobes) and two at the back (occipital and parietal lobes).
The frontal lobe is linked to your personality and it is where you have your bright ideas.
The temporal lobe is where you hear and understand what people say to you.
The occipital lobe is where you work out what your eyes see.
The parietal lobe is where you record touch, heat and cold, and pain.
The left half of the brain controls the right side of the body. The right half controls the left side.
One half of the brain is always dominant (in charge). Usually, the left brain is dominant, which is why
90% of people are right-handed.
