Spike patterns have been reported to encode sensory information in several brain areas. Here we assess the role of specific patterns in the neural code, by comparing the amount of information transmitted with different choices of the readout neural alphabet. This allows us to rank several alternative alphabets depending on the amount of information that can be extracted from them. One can thereby identify the specific patterns that constitute the most prominent ingredients of the code. We finally discuss the interplay of categorical and temporal information in the amount of synergy or redundancy in the neural code.
据报道，尖峰模式在多个脑区对感觉信息进行编码。在此，我们通过比较使用不同读出神经字母表选择时所传输的信息量，来评估特定模式在神经编码中的作用。这使我们能够根据可从中提取的信息量对几种备选字母表进行排序。由此可以识别出构成编码中最显著成分的特定模式。我们最后讨论了神经编码中协同或冗余量方面的分类信息和时间信息之间的相互作用。
