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(受試者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(減)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假設(shè))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. |

We were disappointed to learn about Chrysler Dodge’s new car, the Viper. It must be the most ungreen car of recent years. It can carry only two people but it is extremely powerful, with a top speed of 165 mph. It will go from 0-60 mph in just four seconds. From our point of view, the worst feature is the petrol consumption: just 15miles per gallon. This is a car from the past, a gas-guzzler for people who want to show off and who don’t care about polluting the air. |
ASTON MARTIN DB2/4(1975) This car is a fine example of the power and elegance of the Aston Martin sports cars of the 1950s. It was developed from the earlier DB2, but this model was intended to give more room: if you look in the back window, you will see two small seats. But the main attraction of Aston Martins was their power: almost 200kph. 765 of these cars were manufactured between 1953 and 1959. This model was donated to the museum in 1986. |

In the future, lorry drivers could be free to doze or read a newspaper as their vehicles travel along the motorways of the world, according to Mercedes-Benz. They say that lorries could travel on special lorry-only lanes, and that electronic safety systems would ‘read’ the road ahead, keep a safe distance between vehicles and set the speed. The driver would only take over when the lorry left the motorway and returned to normal roads. This vision of the future was explained at he Hanover Commercial Vehicle Show recently, at which Mercedes showed their EXT-92 experimental lorry of the future. Among the many features, the lorry would include a luxurious living area for the driver, complete with bunk bed, microwave cooker, television, telephone and fax machine. |
