Specific brain disorders can affect the
perception of music in a very specific way. Experiments done on epileptics
decades ago showed that stimulating certain areas of the temporal lobe on both
sides of the brain awakened "musical memories"—vivid re-creations of melodies
that the patients had heard years earlier. Lesions in the temporal lobe can
result in so-called musicogenic epilepsy, an extremely rare form of the disorder
in which seizures are triggered by the sound of music. Autism offers an even
greater puzzle. People with this condition are mentally deficient, yet most are
proficient musicians; some are "musical savants" possessed of extraordinary
talent. The opposite is true of the less than 1 percent of the population who suffer from {{U}}amusia{{/U}}, or tree tone deafness. They literally cannot recognize a melody, let alone tell two of them A. affect the understanding of music in almost every possible way B. stimulate the memorizing of music he/she knew before C. hinder musical understanding of the brain in some special ways D. restrain the memorizing of music he/she knew before [填空题]The internal workings of the brain can be replicated by robots.
[简答题]There are limits to how much the brain can multitask because the brain has trouble______.
[单项选择]Very often, the human eye and brain can recognize familiar shapes even if all but a few significant points are left out. It is this creative power of the human eye and brain that may someday allow profoundly deaf people to talk in sign language over a special "telephone". Researchers have found that thirteen spots of light on each hand and one spot on the nose--to show head motion and provide a reference point for hand position--are sufficient for the performing of American Sign Language. The bright spots are produced by attaching pieces of a special tape to the nose, fingertips, and wrists and adjusting a closed-circuit television system so that only the bright spots appear on the screen of the receiver. After a few minutes of familiarization, pairs of deaf people are able to communicate freely over television. Deaf people and other sign readers can, of course, understand sign language on commercial television. But widespread link-ups of television systems for personal communication a
