问题     In Second Nature, Nobel Prize-winning neuroscientist Gerald Edelman argues that the brain and mind are unified, but he has little patience with the claim that the brain is a computer. Fortunately for the general reader, his explanations of brain function are accessible, reinforced by concrete examples and metaphors.
    Edelman suggests that thanks to the recent development of instruments capable of measuring brain structure within millimeters and brain activity within milliseconds, perceptions, thoughts, memories, willed acts, and other mind matters traditionally considered private and impenetrable to scientific scrutiny now can be correlated with brain activity. Our consciousness ( a "first-person affair" displaying intentionality, reflecting beliefs and desires, etc. ), our creativity, even our value systems, have a basis in brain function.
    The author describes three unifying insights that correlate mind matters with brain activity. First, even distant neurons will establish meaningful connections (circuits) if their patterns are synchronized. Second, experience can either strengthen or weaken synapses (neuronal connections) . Finally, there is reentry, the continued signaling from one brain region to another and back again along massively parallel nerve fibers.
    Edelman concedes that neurological explanations for consciousness and other aspects of mind are not currently available, but he is confident that they will be soon. Meanwhile, he is comfortable hazarding a guess: "All of our mental life...is based on the structure and dynamics of our brain. " Despite this optimism about the explanatory powers of neuro-science, Edelman acknowledges the pitfalls in attempting to explain all aspects of the mind in neurological terms. Indeed, culture—not biology—is the primary determinant of the brain’s evolution, and has been since the emergence of language, he notes.
    However, I was surprised to learn that he considers Sigmund Freud as "the key expositor of the effects of unconscious processes on behavior. " Such a comment ignores how slightly Freud’s conception of the unconscious, with its emphasis on sexuality and aggression, resembles the cognitive unconscious studied by neuroscientists.
    Still, Second Nature is well worth reading. It serves as a bridge between the traditionally separate camps of "hard" science and the humanities. Readers without at least some familiarity with brain science will likely find the going difficult at certain points. Nonetheless, Edelman has achieved his goal of producing a provocative exploration of "how we come to know the world and ourselves. "
Gerald Edelman would probably support the idea that______.
选项 A、the brain co-functions with the mind
B、the brain works like a computer
C、the brain has an accessible function
D、the brain sends signals to the mind
答案A
解析 题目问：杰拉尔德·埃德尔曼可能会赞同哪种观点。根据文中第一段第一句“In Second Nature…that the brain is a computer．”可知，杰拉尔德·埃德尔曼认为，大脑与思维是一致的，但他并不赞同那种将人脑比作电脑的观点。据此可以推知，大脑与思维相互协调，共同发挥作用，但人脑并不是像电脑那样工作。因此A项为正确答案。
