摘要：

Studies of vision in the horseshoe crab show that the animal's brain exerts substantial control over just what the eyes detect. At night, for example, the brain increases the eye's sensitivity to light by a factor of a million, thereby enabling the male to find a suitable mate in the dark. Simulations on a Connection Machine model the amplification process.
