u       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.

u       No one knows how consciousness works — it is one of science’s last great mysteries.

u       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.

u       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).

u       The frontal lobe is linked to your personality and it is where you have your bright ideas.

u       The temporal lobe is where you hear and understand what people say to you.

u       The occipital lobe is where you work out what your eyes see.

u       The parietal lobe is where you record touch, heat and cold, and pain.

u       The left half of the brain controls the right side of the body. The right half controls the left side.

u       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.
