在许多情况下,感觉系统的性能受到刺激的物理性质的限制。对于视觉来说,光的量子特性限制了适应黑暗的观察者的检测能力;直到现在,我们才开始意识到这种微妙敏感性背后的生物物理机制的微妙之处。
The performance of sensory systems in many cases is limited by the physical nature of the stimulus. For vision, the quantal nature of light limits detection by dark-adapted observers; only now are we beginning to be aware of the subtleties in the biophysical mechanisms underlying this exquisite sensitivity.
