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.
