Ask Dr ? Jeffers | This month Dr. Jeffers is answering questions about the human brain and how it works. |
Dear Dr. Jeffers, One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to ‘read minds’. Is there any truth to this story/ —Jane Leon, New York, USA Dear Ms. Leon, Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects(受试者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(减)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time. It’s not quite mind reading, but it’s certainly a first step. —Dr. J. | |
Dear Dr. Jeffers, My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not? —Glenn Lewis, Vancouver, Canada Dear Mr. Lewis, It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction. —Dr. J. |

One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.
We cautiously began a conversation and spoke about a wide rang of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked,
“My I get you something?”
“A coffee would be nice.”
Then I bought him a cup of coffee, we talked more, and he accepted another cup of coffee. Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked,
“How did you get to know Mr. Galbreath?”
“Who?”
“The man you were sitting with. He is chairman of the Board of Churchill Downs.”
I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world’s richest and most powerful men!
My few minutes with Mr. Galbreath changed my life. Now I try to treat everyone with
respect, no matter who I think they are, and no matter another human being with kindness and sincerity.
