神经元膜电位记录的卷积度量

Convolution Metric for Neuron Membrane Potential Recordings

Garrett N. Evans

摘要:

我提供了一个卷积度量,它将神经膜电位记录作为参数,并比较它们的阈下特征以及其中尖峰的时间和数量--用记录之间的单个“距离”总结这些差异。基于van Rossum 2001年对脉冲序列的度量,该度量依赖于它对输入数据执行的卷积运算。用于卷积的内核是精心选择的,使得它产生期望的频率空间响应,并且与van Rossum的内核不同,导致度量在附近的尖峰时间之间的差异和在相同时间的膜电位值之间的差异上都是一阶的:这是一个重要的特征。31页,4位数字。

英文摘要:

I provide a convolution metric which takes neural membrane potential recordings as arguments and compares their subthreshold features along with the timing and number of spikes within them--summarizing differences in these with a single "distance" between the recordings. Based on van Rossum's 2001 metric for spike trains, the metric relies on a convolution operation that it performs on the input data. The kernel used for the convolution is carefully chosen such that it produces a desirable frequency space response and, unlike van Rossum's kernel, causes the metric to be first order both in differences between nearby spike times and in differences between same-time membrane potential values: an important trait. 31 pages, 4 figures.
