The child wears the helmet while playing the game, and brain-activity data is transmitted wirelessly to a base station hooked up to a computer.
Using a mixed 2 (group: ACT, Control)×2 (condition: wins, losses)×2 (time: pre, lost) design, the self-report and behavioral aspects of the slot machine activity, in addition to the brain activation data were compared across time.
Total activity data were used for analyses.
Moreover, because the control study also required subjects to passively view emotional and neutral images, our brain activity data cannot be attributed to unconscious image evaluation processes.
And in 2009, a separate team of researchers reported using brain activity data to tell what number a person was counting.
For instance, STE is used to analyze brain activity data for the detection and identification of asymmetric dependences of brain regions in epileptic seizure activity [13].
The magnitude of this contribution was indirectly estimated from a comparison of the phantom (brain activity only) and the human (brain and extra-brain activity) data for each camera.
As the study aimed on preparatory brain activity only and behavioural data were not considered of relevance for the interpretation of the results, no additional behavioural data were collected (for recent studies adopting a similar approach see [14], [15]).
Furthermore, to further characterize the relevance of extra-brain activity, phantom and human data were also compared in terms of the % difference of their respective IRNC and ACSC databases.
Components related to eye blinks or artifacts in the signal that could be clearly distinguished from brain activity were removed from the data.
To noninvasively assess resting-state brain activity, resting-state MEG (rsMEG) data were acquired in all subjects and quantified based on the SAMg2 method.
