人们经常盘问计算机专家,计算机究竟能否象人那样思维?他们的回答是饶有兴味的、可取的。不过,我想从生物学家的观点来研讨这个问题。我相信,通过对我们的大脑和计算机的活动情况的考查,能逐步接近于一种答案。原来,用作构建大脑和计算机的基本元件的活动行为是迥然不同的。计算机的基本元件是晶体管,它们起开关的作用。开关开时,电子就通过晶体管;开关闭时,信号就通不过。这两种状态相当于计算机使用的二进计数制中的1和0。人们一般认为大脑的基本元件是突触,它们亦起类似开关的作用。大脑中的电路取决于这些能开能关的突触开关。改变开关就改变电路;这样就改
People often interrogate computer experts, computer whether people like that way of thinking? Their answer is interesting, desirable. However, I would like to discuss this issue from the biologist's point of view. I believe that by examining the activities of our brains and computers, we can gradually come close to one answer. It turned out that the activities used to construct the basic components of the brain and computer are quite different. The basic components of a computer are transistors, which act as switches. When the switch is on, the electron passes through the transistor. When the switch is off, the signal will not pass. These two states correspond to 1 and 0 of the binary count system used by computers. People generally think that the basic components of the brain are synapses, they also play a similar role in the switch. The circuitry in the brain depends on these synaptic switches that can be switched off. Change the switch to change the circuit; so change
