在任何科学理论中,概念框架已经决定了结果的性质和可能的范围。过于简单化会妨碍对系统的充分描述,而过于详细的描述除了会浪费时间和资源之外,还会掩盖观察到的现象背后的基本原理。在理论神经科学中,这是一个重要问题,因为从详细的生物物理描述到抽象的计算模型,描述水平差异很大。我们在最近关于大鼠皮层锥体神经元体细胞迭代构建的前馈网络同步性的报告中讨论了适当建模水平的问题(Reyes,2003)。
In any scientific theory, the conceptual framework already determines the nature and possible scope of the results. Oversimplification prevents an adequate description of the system, whereas too detailed a description obscures the fundamental principles behind the observed phenomena in addition to misspending time and resources. In theoretical neuroscience, this is an important issue because the description level varies widely from detailed biophysical descriptions to abstract computational models. We discuss the question of the appropriate modeling level in the context of a recent report on synchrony in iteratively constructed feed-forward networks of rat cortex pyramidal neuron somata (Reyes, 2003).
