Goldman-Rakic reports important new data on cortical development in rhesus monkeys. Some of her findings, especially concurrent cortical synaptogenesis, may be related to cognitive capacities that develop in infancy. The developmental pattern of concurrent synaptogenesis in rhesus is consistent with a straightforward model of relations between brain and cognitive development: Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in both human and rhesus infants. Other general brain changes, especially in the electroencephalogram, also seem to correlate with these levels, as well as with other levels that develop at other periods. In the simplest form of the model, these several factors all show synchronous developmental discontinuities at the time of emergence of a level. Specific research methods are available for specifying when discontinuities occur in development of both brain and behavior.
戈德曼-拉基奇报告了关于恒河猴皮质发育的重要新数据。她的一些发现，尤其是同时发生的皮质突触形成，可能与婴儿期发展出的认知能力有关。恒河猴同时发生突触形成的发育模式与大脑和认知发展之间关系的一个简单模型一致：据推测，同时发生的突触形成为婴儿中期一系列已在人类和恒河猴婴儿身上得到实证记录的发育水平奠定了主要的皮质基础。其他一般的大脑变化，尤其是脑电图方面的变化，似乎也与这些水平以及在其他时期发展出的其他水平相关。在该模型的最简单形式中，这几个因素在一个水平出现时都显示出同步的发育间断。有特定的研究方法可用于确定大脑和行为发育过程中何时出现间断。
