在多患者颅内记录中识别刺激驱动的神经活动模式

Identifying stimulus-driven neural activity patterns in multi-patient intracranial recordings

Dartmouth College(达特茅斯学院)

摘要:

识别刺激驱动的神经活动模式对于研究认知的神经基础至关重要。这在颅内数据集中可能特别具有挑战性,其中电极位置通常因患者而异。本章首先概述了在一般情况下识别刺激驱动的神经活动模式的主要挑战。接下来,我们将回顾几种特定于模态的注意事项和方法,并讨论颅内记录特有的几个问题。在此背景下,我们将考虑各种受试者内和跨受试者的方法来识别和建模多患者颅内记录中刺激驱动的神经活动模式。这些方法包括广义线性模型,多变量模式分析,表征相似性分析,联合刺激活动模型,分层矩阵分解模型,高斯过程模型,几何对齐模型,受试者间的相关性,和受试者间的功能相关性。从最近的文献中的例子来说明的主要概念,并提供每种方法的概念直观。

英文摘要:

Identifying stimulus-driven neural activity patterns is critical for studying the neural basis of cognition. This can be particularly challenging in intracranial datasets, where electrode locations typically vary across patients. This chapter first presents an overview of the major challenges to identifying stimulus-driven neural activity patterns in the general case. Next, we will review several modality-specific considerations and approaches, along with a discussion of several issues that are particular to intracranial recordings. Against this backdrop, we will consider a variety of within-subject and across-subject approaches to identifying and modeling stimulus-driven neural activity patterns in multi-patient intracranial recordings. These approaches include generalized linear models, multivariate pattern analysis, representational similarity analysis, joint stimulus-activity models, hierarchical matrix factorization models, Gaussian process models, geometric alignment models, inter-subject correlations, and inter-subject functional correlations. Examples from the recent literature serve to illustrate the major concepts and provide the conceptual intuitions for each approach.
