A new study of the brain is helping scientists better understand how humans process language. One of the patients is a woman with epilepsy(羊癫疯). Doctors are (31) Denise Harris to see if she is a good (32) for an operation that could stop her seizures. They are monitoring her through wire electrodes (33) in her brain. But (34) she is in the hospital, she is also helping scientists understand (35) the brain works with language. The study (36) a part of the frontal lobe called Broca’s area. The electrode implants have shown that the area very quickly (37) three different language functions. Eric Halgren, one of the main investigators, says they found different (38) doing, at different times, different processes all (39) a centimeter. The first function deals with (40) a word. The second deals with understanding the word’s meaning within a sentence. (41) the third lets us speak the word. Ned Sahin, a researcher, says scientists (42) for some time that traditional explanations for how parts of the brain work need to be (43) One such belief is that there is a (44) of language tasks between two very different parts of the brain. One is Broca’s area (45) the front. The other is Wernicke’s area (46) back in the brain. The belief is that Broca’s area is (47) speaking and that Wernicke’s area is responsible for comprehending. (48) the new study shows that Broca’s area is (49) both speaking and comprehension. He says this shows how parts of the brain (50) more than one task.
