Abstract：
Perception of quantities, such as numerosity, timing, and size, is essential for behavior and cognition. Accumulating evidence demonstrates neurons processing quantities are tuned, that is, have a preferred quantity amount, not only for numerosity, but also other quantity dimensions and sensory modalities. We argue that quantity-tuned neurons are fundamental to understanding quantity perception. We illustrate how the properties of quantity-tuned neurons can underlie a range of perceptual phenomena. Furthermore, quantity-tuned neurons are organized in distinct but overlapping topographic maps. We suggest that this overlap in tuning provides the neural basis for perceptual interactions between different quantities, without the need for a common neural representational code.
摘要：
对数量的感知，比如数字，定时,和大小，对行为和认知至关重要。越来越多的证据表明神经元的处理量得到了调整，也就是说,有一个首选的数量，不仅仅是为了数字，还有其他数量维度和感官模式。我们认为，数量调节的神经元是理解数量感知的基础。我们说明了数量调节神经元的特性如何构成一系列感知现象的基础。此外，数量调节的神经元被组织在不同但重叠的地形图中。我们建议这种调谐的重叠为不同量之间的感知相互作用提供了神经基础，不需要通用的神经表示代码。
