[单项选择]Yasuhisa Shizoki, a 51-year-old MP from Japan’s ruling Liberal Democratic Party (LDP), starts tapping his finger on the dismal economic chart on his coffee table. "Unless we change the decision-making process," he says bluntly, "we are not going to be able to solve this kind of problem." With the economy in such a mess, it may seem a bit of a diversion to be trying to sort out Japan’s political structures as well as its economic problems. But Mr Shiozaki can hardly be accused of time-wasting. He has consistently prodded the government to take a firm hand to ailing banks, and has given warning against complacency after a recent rise in share prices. Far from being a distraction, his latest cause highlights how far Japan is from genuine economic reform. Since cowriting a report on political reform, which was released by an LDP panel last week, Mr Shiozaki has further upset the party’s old guard. Its legionaries, flanked by columns of the bureaucracy, continue to hamper most attempts to

[单项选择] Behavioral psychologists apprehend that conditioned fear responses to atone previously paired with a shock diminish, if the tone is repeatedly presented without the shock, a process known as extinction. Since Parlor it has been hypothesized that this extinction does not erase conditioning, but forms a new memory. Research has now demonstrated that destruction of the infralimbic cortice blocks recall of fear extinction, indicating that it might store long-term extinction memory. Infralimbic neurons recorded during fear conditioning and extinction fire to the tone only when rats are recalling extinction on the following day, and rats indicating the least fear responses also demonstrate the greatest increase in infralimbic tone responses. Conditioned tones paired with brief electrical stimulation of infralimbic cortex elicit low fear responses in rats that have not undergone extinction. Thus, stimulation resembling extinction-induced infralimbic tone responses is able to simulate extinc
