　　The Relationship between Brain Process with Mental Experience

　　By 1950, the results of attempts to relate brain processesto mental experience appeared rather discouraging. Suchvariations in size, shape, chemistry, conduction speed, excitationthreshold, and the like as had been demonstrated in nerve cellsremained negligible in significance for any possible correlationwith the manifold dimensions of mental experience.

　　Near the turn of the century, it had been suggested by Hering that different modes of sensation,such as pain, taste and color, might be correlated with the discharge of specific kinds of nervousenergy, However, subsequently developed methods of recording and analyzing nerve potentialsfailed to reveal any such qualitative diversity. It was possible to demonstrate by other methodsrefined structural differences among neuron types; however, proof was lacking that the quality ofthe impulse or its conduction was influenced by these differences, which seemed instead toinfluence the developmental patterning of the neural circuits. Although qualitative variance amongnerve rigidly disproved, the doctrine was generally abandoned in favor of the opposing view,namely, that nerve impulses are essentially homogeneous in quality and are transmitted as“common currency” throughout the nervous system. According to this theory, it is not the qualityof the sensory nerve impulses that determines the diverse conscious sensations they produce,but, rather, the different areas of the brain into which they discharge, and there is some evidencefor this view. In one experiment, when an electric stimulus was applied to a given sensory field ofthe cerebral cortex of a conscious human subject, it produced a sensation of the appropriatemodality for that particular locus, that is, a visual sensation from the visual cortex, an auditorysensation from the auditory cortex, and so on. Other experiments revealed slight variations in thesize, number, arrangement, and interconnection of the nerve cells, but as for as psychoneuralcorrelations were concerned, the obvious similarities of these sensory fields to each other seemedmuch more remarkable than any of the minute differences.

　　However, cortical as diverse as those of red, black, green and white, or touch, cold, warmth,movement, pain, posture and pressure apparently may arise through activation of the samecortical areas. What seemed to remain was some kind of differential patterning effects in the brainexcitation: it is the difference in the central distribution of impulses that counts. In short, Braintheory suggested a correlation between mental experience and the activity of relativelyhomogenous nerve -cell units conducting essentially homogeneous impulses throughhomogeneous cerebral tissue. To match the multiple dimensions of mental experiencepsychologists could only point to a limitless variation in the spatiotemporal patterning of nerveimpulses.

　　1. Up until 1950, efforts to establish that brain processes and mental experience are related wouldmost likely have been met with

　　[A] vexation [B] irritability [C] discouragement [D] neutrality

　　2. The author mentions “common currency” primarily in order to emphasize the

　　[A] lack of differentiation among nerve impulses in human beings.

　　[B] similarities in the views of the scientists.

　　[C] similarity of sensations of human beings.

　　[D] continuous passage of nerve impulses through the nervous system.

　　3. Which of the following theories is reinforced by the depiction of the experiment in lines 16—19?

　　[A] Cognitive experience manifested by sensory nerve impulses are influenced by the area of thebrain stimulated.

　　[B] Qualitative diversity in nerve potentials can now be studied more accurately.

　　[C] Sensory stimuli are heterogeneous and are greatly influenced by the nerve sensors theyproduce.

　　[D] Differentiation in neural modalities influences the length of nerve transmissions.

　　4. It can be inferred from the passage that which of the following exhibit the LEAST qualitativevariation?

　　[A] Nerve cells. [B] Nerve impulses.

　　[C] Cortical areas. [C] Spatial patterns of nerve impulses.

　　答案详解：

　　1. C. 令人失望。答案见文章的第一句话“到了1950年，大脑活动过程和精神感受有关系的实验结果看起来令人沮丧。”

　　A. 令人恼火。 B. 激怒。 D. 中立。均不对。

　　2. A. 在人的神经脉冲中缺少变异(差别)。Common currency本义是一般通用。这里的上下问决定了它的含义“无变异脉冲(普通脉冲)”。第二段“虽然神经能量中的质变理论从没有受到严厉的驳斥，但这一学说被普遍放弃，而赞成其对立的观点;那就是：神经脉冲在质量沙锅内基本相似，并作为无变异脉冲(普通脉冲)经神经系统传送。”所以普通脉冲就是指神经脉冲无变异，在质量上基本相似。

　　B. 科学家观点上的相似性。 C. 人类感觉相似性。 D. 神经脉冲连续不断通过神经系统。这三项和common currency 无关。

　　3. A. 受刺激的大脑部位影响感觉神经脉冲所显示的认知感受。在第二道题译文下面“根据这一理论，不是感觉神经脉冲的质量决定它们所产生的各种有意识的感觉。而是由脉冲在大脑中释放的不同部位决定，并且有证据证明这一论点。”见难句译注3。

　　B. 现在对神经潜力的质量变化可以进行更精彩的研究。 C. 感官刺激是异源的'，并深受它们所产生的神经感觉(感受器)的影响。 D. 神经形态上的差异影响神经传递长度。

　　4. B. 神经脉冲。这在第2题答案A中译注(即第二段)已有明确的答复。“神经脉冲在质量上基本相似……。”

　　A. 神经细胞。见难句译注2，“有可能用其他办法来显示神经细胞类型之间细微的结构差异。” C. 外皮区域(部位)。 D. 神经脉冲空间模式。见难句译注5和本文最后一句“为了和精神感受多样性吻合，心理学家只能指明神经脉冲时空模式上的无限差异。”这说明，它不是 “Leastqualitative variation.”

　　A wise man once said that the only thing necessary for the triumph of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people.

　　Day after day my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability.

　　Accountability isn’t hard to define. It means that every person is responsible for his or her actions and liable for their consequences.

　　Of the many values that hold civilization together -- honesty, kindness, and so on -- accountability may be the most important of all. Without it, there can be no respect, no trust, no law -- and, ultimately, no society.

　　My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people’s behavior are far less effective than internal restraints such as guilt, shame and embarrassment.

　　Fortunately there are still communities -- smaller towns, usually -- where schools maintain discipline and where parents hold up standards that proclaim: “In this family certain things are not tolerated -- they simply are not done!”

　　Yet more and more, especially in our larger cities and suburbs, these inner restraints are loosening. Your typical robber has none. He considers your property his property; he takes what he wants, including your life if you enrage him.

　　The main cause of this break-down is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it’s the criminal who is considered victimized: by his underprivileged upbringing, by the school that didn’t teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn’t provide a stable home.

　　I don’t believe it. Many others in equally disadvantaged circumstances choose not to engage in criminal activities. If we free the criminal, even partly, from accountability, we become a society of endless excuses where no one accepts responsibility for anything.

　　We in America desperately need more people who believe that the person who commits a crime is the one responsible for it.
