First, the paradigm was explained and performed on a desktop computer outside the scanner and children had to solve one to three 20 s blocks of practice trials by pressing the corresponding mouse button.
Outside the scanner, the children performed a classical global/local task that allows the determination of their visual bias (i.e., global or local; see [ 5, 6, 25, 26]).
This system, named CPS-SLAM, consists of a parent robot with a 3D laser scanner and child robots with target markers.
After taking each one, the impact on brain activity was recorded in a scanner while the children were shown "social" pictures of human faces or "non-social" pictures of cars.
Imaging slew rates and gradient amplitudes were reduced to approximately 30 and 75%% of their maximal values to reduce the acoustic noise levels of the MRI scanner and ensure sleeping children remained asleep for the duration of the scan.
It has pledged to raise an initial £3.5m for new equipment, including an intraoperative MRI scanner, family facilities and child-friendly artwork.
On Mars, Paxton allows T'Pol and Tucker see the baby, and T'Pol uses her scanner to learn that the child is unwell (and that Paxton has been using Rigelian gene therapy to treat himself).
A promising alternative is the use of a mock scanner or tunnel to prepare children for MRI investigation [ 9].
A recent study using a mock scanner or tunnel to train children yielded a success rate for completion of at least one single fMRI run of 82% (41/48) in a mixed group of 4 6 year-old children, consisting of both healthy children and children with epilepsy [ 25].
