Sensitivity of the resting-state haemodynamic response function estimation to autonomic nervous system fluctuations

A collection of 24 brain maps. Each brain map is a 3D array of values representing properties of the brain at different locations.

### Collection description

<p>We have developed a tool to retrieve the hemodynamic response function from resting state fMRI data (rs-HRF). The procedure, based on point process, is described here http://www.ncbi.nlm.nih.gov/pubmed/23422254 and partially validated here https://peerj.com/preprints/1317/.</p><p>In this collection we report the relevantr rs-HRF parameters (height, time to peak and width) as well as the bias on their estimation introduced by several strategies of physiological noise correction, for three datasets: the 7T TRT by Gorgolewski et al. (http://fcon_1000.projects.nitrc.org/indi/CoRR/html/mpg_1.html) and the NKI-Rockland for TR=0.645 s and TR=2.5s (http://fcon_1000.projects.nitrc.org/indi/pro/nki.html)</p>

本集合汇集了24幅脑图谱。每一幅脑图谱均由三维数值数组构成，用以表征大脑在不同位置处的属性。

### 集合描述

我们研发了一套工具，旨在从静息态功能磁共振成像数据（rs-HRF）中提取血流动力学反应函数（静息态血流动力学反应函数提取工具）。该流程基于点过程，具体描述可参见http://www.ncbi.nlm.nih.gov/pubmed/23422254，其部分验证信息请参阅https://peerj.com/preprints/1317/。

在本集合中，我们报告了与静息态血流动力学反应函数相关的参数（峰值高度、达峰时间及宽度），以及由多种生理噪声校正策略引入的估计偏差，涉及以下三个数据集：Gorgolewski等人所进行的7T TRT研究（http://fcon_1000.projects.nitrc.org/indi/CoRR/html/mpg_1.html）以及NKI-Rockland在TR=0.645秒和TR=2.5秒下的研究（http://fcon_1000.projects.nitrc.org/indi/pro/nki.html）。
