五个神经元上开、闭凸码的分类

Classification of Open and Closed Convex Codes on Five Neurons

Sarah Ayman Goldrup, Kaitlyn Phillipson

摘要:

神经代码,表示为二进制字符串的集合,编码神经活动并显示刺激之间的关系。某些神经元,称为位置细胞,已经被实验证明在空间的凸区域中放电。一个自然的问题是:哪些神经代码可以作为凸集的交集模式出现?虽然过去的研究已经建立了几个标准,凸性的完整条件还不知道超过四个神经元的代码。我们将所有具有五个神经元的神经代码分类为凸/非凸代码。此外,我们调查这些代码可以表示为开放与封闭的凸集。有趣的是,我们发现了一个代码,这是一个开放的,但不是封闭的凸代码,并证明了这种现象的一个最小的例子。

英文摘要:

Neural codes, represented as collections of binary strings, encode neural activity and show relationships among stimuli. Certain neurons, called place cells, have been shown experimentally to fire in convex regions in space. A natural question to ask is: Which neural codes can arise as intersection patterns of convex sets? While past research has established several criteria, complete conditions for convexity are not yet known for codes with more than four neurons. We classify all neural codes with five neurons as convex/non-convex codes. Furthermore, we investigate which of these codes can be represented by open versus closed convex sets. Interestingly, we find a code which is an open but not closed convex code and demonstrate a minimal example for this phenomenon.
