Heritability of head motion during resting state functional MRI in 462 healthy twins
2014
NeuroImage
Preserved Fulltext
Here we investigate whether HM during resting state functional MRI (RS-fMRI) is influenced by genetic factors in a sample of 462 twins (65% female; 101 MZ (monozygotic) and 130 DZ (dizygotic) twin pairs ...
Head motion (HM) is a critical confounding factor in functional MRI. ...
We are very grateful to the twins for their generosity of time and willingness to participate in our studies. ...
