How can teens be so clever, accomplished, and responsible—and recklessat the same time? Easily, according to two physicians at Children’s Hospital Boston and Harvard Medical School (HMS) who have been exploring the unique structure and chemistry of the adolescent brain. “The teenage brainis not just an adult brain with fewer miles on it,” says Frances E. Jensen, aprofessor of neurology. “It’s a paradoxical time of development.These are people with very sharp brains, but they’re not quite sure what to do with them.”
In animals, movement is coordinated by a cluster of neurons in the spinal cord called the central pattern generator (CPG). This produces signals that drive muscles to contract rhythmically in a way that produces running or walking, depending on the patternof pulses. A simple signal from the brain instructs the CPG to switch between different modes, such as going from a standstill to walking.
- 2. 罗马角斗场
The Romans glorified the bravery shown in the arena, but trivialized the events and degraded the participants. Mosaic pictures of executions and combats, graphicallyviolent to our eyes, were displayed in the public rooms and even dining rooms in the homes of wealthy Romans.

- No one in Parliament would know better than Peter Garrett what largesse copyright can confer so it may seem right that he should announce a royalty for artists, amounting to 5 per cent of all sales after the original one, which can go on giving to their families for as much as 150 years. But that ignores the truth that copyright law is a scandal, recently exacerbatedby the Free Trade Agreement with the US which required extension of copyright to 70 years after death.
Is it scandalous that really valuable copyrights end up in the ownership of corporations (although Agatha Christie’s no-doubt worthy great-grandchildren are still reaping the benefits of West End success for her who dunnits and members of the Garrick Club enjoy the continuing fruits of A.A. Milne’s Christopher Robin books)? No. The scandal is that bien pensants politicians have attempted to appear cultured by creating private assets which depend on an act of Parliament for their existence and by giving away much more in value than any public benefit could justify. In doing so they have betrayed our trust.
