The neurochemical basis of memory has been approached experimentally in four different ways: the bioassay; the interventive approach; the interventive-correlative approach; and the correlative approach. These approaches are fundamentally similar to those used for the study of the chemistry of any behavior. Each of these approaches has serious limitations, and significant progress has only been made by combinations of more than one. I shall discuss each of these approaches in turn.
生物测定法；干预法；干预关联法；以及关联法。这些方法从根本上类似于用于研究任何行为的化学机制所采用的方法。这些方法中的每一种都有严重的局限性，只有通过不止一种方法的组合才能取得显著进展。我将依次讨论这些方法。
