“…The degree of head motion during scanning was greater in the 13-year-olds compared with the two older age groups on the two most affected parameters (Mayer et al, 2007;Yoo et al, 2005), viz translation in the z direction (Tz; F (2, 63) = 5.40; p = .007) and rotation in the x direction (Rx; F (2, 63) = 6.77; p = .002). In order to control for the confounding effect of head motion we applied 3 corrections to our data.…”

“…In addition to head movement influencing the data acquisition methods by altering, for example, the position of the brain in the MRI field, 100 the motion itself can also induce neural activity. Jansen and colleagues 101 investigated the effect of movement when EEG signals are used as predictors for BOLD signals.…”

“…Head motion is a major source for fMRI data quality deterioration, leading to fMRI image artifacts and false detections and misinterpretations of brain activities [6][7][8][9][10]. Head motions associated with fMRI tasks are potentially more significant, while the brain responses during these tasks are the information of interest.…”

“…Different real-time feedbacks provide the head motion information to the subjects during fMRI scanning, so that they can stabilize the head position voluntarily [9,14]. Methods for image correction include data processing in k-space [14], motion tracking [7,15], prospective acquisition correction [6], realignment of volumetric image data [8], etc. However, all these methods can only suppress, or detect and correct, a certain part of head motion.…”

In this work, we studied human head motions during upper extremity motor task, conducted in functional magnetic resonance imaging (fMRI) studies. The experiments were performed on a mock up of the MRI bench. Three kinds of linear movements in the caudal-cranial, left-right and anterior-posterior directions, a reaching movement as well as single joint movements at shoulder, elbow and wrist, were investigated at three different speeds with the right arm. Optical markers tracked by a high-precision motion tracking system were used to detect head and arm movements. For each task, the head moved principally in the direction of right-caudal-posterior to left-cranial-anterior, parallel to the line from the right shoulder joint to the head. No principal rotation axis was observed. The translational and rotational head motions were 1.7 ~ 8.4 mm and 0.15deg ~ 0.96deg, respectively. We then applied a special head fixation to stabilize the head, and repeated all the experiments. The translational and rotational head motions were significantly suppressed by 78% and 73%, to the range of 0.3 ~ 2.4 mm and 0.04deg ~ 0.39deg.
