摘要:

神经元记录的长时间序列由相互连接的神经元网络活动产生,但如何提取神经元特性仍依赖经验方法。本文综述了基于网络模型的数据分析方法,用于从神经元和星形胶质细胞的电生理记录及钙成像记录中恢复生理参数。随后,本文介绍了记录技术以及激活事件,如簇发放电(burst)、簇间期(interburst)以及上行(Up)和下行(Down)状态。接着,本文描述了为检测和分割这些事件而开发的时间序列分割方法。为解释从时间序列中提取的统计特征,本文提出了基于突触短时程可塑性和后超极化的神经元群体计算模型。本文讨论了如何校准这些模型,使其能够复现实验时间序列中观测到的统计特征。这些模型通过比较数值模拟与实验的统计矩或完整分布,来提取特定参数。最后,本文讨论了经校准的模型用于预测某些参数对回路行为选择性影响的案例,这些特性若通过实验解析会十分困难。

英文摘要:

Long-time series of neuronal recordings are resulting from the activity of connected neuronal networks. Yet how neuronal properties can be extracted remains empirical. We review here the data analysis based on network models to recover physiological parameters from electrophysiological and calcium recordings in neurons and astrocytes. After, we present the recording techniques and activation events, such as burst and interburst and Up and Down states. We then describe time-serie segmentation methods developed to detect and to segment these events. To interpret the statistics extracted from time series, we present computational models of neuronal populations based on synaptic short-term plasticity and After hyperpolarization. We discuss how these models are calibrated so that they can reproduce the statistics observed in the experimental time series. They serve to extract specific parameters by comparing numerical and experimental statistical moment or entire distributions. Finally, we discus cases where calibrated models are used to predict the selective impact of some parameters on the circuit behavior, properties that would otherwise be difficult to dissect experimentally.
