abide_9002_23R Documentation

Local brain activity at resting state

Description

Imaging measurements for local brain activity at resting state

Usage

data("abide_9002_23")

Format

A list of the curve_set containing the data, coordinates (x,y) where the data have been observed (third dimension is 23), the discrete factor Group (1=Autism; 2=Control), the discrete factor Sex (1=Male; 2=Female), and the continuous factor Age.

Details

The data are a small part of ABIDE fALFF data available at ABIDE: http://fcon_1000.projects.nitrc.org/indi/abide/ fALFF: http://fcp-indi.github.io/docs/user/alff.html and distributed under the CC BY-NC-SA 3.0 license, https://creativecommons.org/licenses/by-nc-sa/3.0/.

The data are fractional Amplitude of Low Frequency Fluctuations (fALFF) (Zou et al. 2008) for Autism Brain Imaging Data Exchange collected resting state functional magnetic resonance imaging (R-fMRI) datasets (Di Martino et al. 2013). This data set in GET contains only a tiny part of the whole brain, namely the region 9002 (the right Cerebelum Crus 1) at slice 23 (see Figure 2 in Mrkvicka et al., 2019) for 514 individuals with the autism spectrum disorder (ASD) and 557 typical controls (TC) as specified in the given Group variable. Further the sex and age of each subject is given.
