摘要

在对大脑活动的分析中，找到只代表大脑活动的时间间隔是很实际的。我们开发了一种新的软件工具，可以帮助搜索和可视化这些间隔。这项工作的基本假设是，代表大脑活动的信号振幅的分布与高斯分布有很大不同。所以我们用负熵作为大脑动态间隔的指示器。因此，所开发的仪器有助于可视化地分析脑电信号，并根据结果进行进一步的数学计算。

Searching and using of time intervals of brain activity in a problem of solving process by estimation of negentropy of EEG

In the analysis of a brain activity it is actual to find time intervals that represents only brain activity. We have developed a new software instrument that helps to search and visualize such intervals. The base assumption of this work is that distribution of the amplitude of signal that represents brain activity is significantly different from a Gaussian distribution. So we use negentropy as an indicator of intervals of brain dynamics. As a result, the developed instrument helps to analyze EEG information visually and make further mathematical calculations with the results.
