科学领域:

  • 神经科学是一个神经科学.
  • 电子生理学 电子生理学

背景情况:

  • 皮质皮质唤起潜能 (CCEPs) 对于研究人类大脑连接性至关重要.
  • CCEP数据容易受到噪音的影响,因此需要进行预处理.
  • 目前的预处理策略在各个研究中各不相同.

研究的目的:

  • 系统地评估常见预处理技术对CCEP量化的影响.
  • 为了比较过和重新引用对CCEP数据的影响.

主要方法:

  • 系统地比较常见平均重新引用和各种过技术.
  • 分析由于预处理而导致的CCEP大小和形态变化.

主要成果:

  • 常见平均重新引用和积极过显著改变了CCEP量化.
  • 在降低噪音方面,过比重新引用或试验平均更有效.
  • 特定的过器切断值 (>0.5Hz高通,<200Hz低通) 和常见的平均值重新引用显著的影响结果.

结论:

  • 现有的CCEP处理方法需要仔细应用,以平衡降噪和数据完整性.
  • 报告预处理方法,特别是重新引用是必不可少的.
  • 建议根据噪声水平选择合适的CCEP处理管道的框架,有利于最小的过.
