Beginning with the first step of visual processing and proceeding outward from that point, the neurons involved in different aspects of vision are distinct. Stated simply, neurons doing different things look different. They often display distinct morphological features and they usually express different molecules. In addition, neurons that perform a common function usually aggregate together to form recognizable layers or compartments that can be studied in isolation because they are neurochemically distinct. Here is found, then, a junction of two major domains in neuroscience research, as discovery of molecular diversity among neurons is exploited to study organization and function of the primate visual system.
从视觉处理的第一步开始，并从该点向外推进，参与视觉不同方面的神经元是不同的。简单地说，做不同事情的神经元看起来不同。它们通常表现出明显的形态特征，并且通常表达不同的分子。此外，执行共同功能的神经元通常聚集在一起形成可识别的层或隔室，由于它们在神经化学上是不同的，因此可以单独进行研究。因此，在这里发现了神经科学研究中两个主要领域的交叉点，因为利用神经元之间分子多样性的发现来研究灵长类视觉系统的组织和功能。
