All six studies found brain activity differences after intervention.
The present study used this novel surface-based ReHo approach to explore the brain functional activity differences between first-episode, drug-naïve MDD patients and healthy controls.
The aims of the present study were therefore to (1) determine brain activity and activation differences between euthymic BD and controls, at rest (EEG band frequency analysis) and during an attentional task, a continuous performance task (EEG ERP wave component analysis).
Since aberrant brain activity in migraine can be noninvasively detected with magnetoencephalography (MEG), The object of this study was to investigate the resting state cortical activity differences between migraineurs and controls and its related clinical characteristics.
Therefore, in order for the classifier to successfully decode brain activity, the difference between two conditions must be systematic and consistent across the majority of the training examples.
Their work, published in today's Science (p. 1582), shows how differences in brain activity make all the difference between remembering and forgetting a word.
To exclude the possibility that differences in brain activity between guessing and passive observation could simply be due to systematic differences in the state of the scanner, we additionally compared the mean fMRI signal between the two sessions (using a two-sample t-test comparing the globals in the two sessions, see Methods).
To reveal the differences of brain activity between the abacus-trained and nontrained groups, two-sample t-tests were performed between the two groups on both EX versus rest and AP versus rest contrasts.
Spreng, R. N., Wojtowicz, M. & Grady, C. L. Reliable differences in brain activity between young and old adults: a quantitative meta-analysis across multiple cognitive domains.
The researchers then performed the same test on a different set of volunteers, this time imaging their brains during the process, to look for differences in brain activity between the age groups.
