Through an analysis of fMRI brain scan images taken from 138 people, the new artificial intelligence algorithm(算法) achieved an accuracy rate of over 99 percent in detecting potential indicators of Alzheimer's (老人痴呆症) . In particular, the method is able to pick out signs of mild cognitiv...

In addition to these main effects, we investigated the possible interactions between the prior scan time variables and the other variables. Other two-way or three-way interactions were not investigated to avoid overly complex and highly computation-intensive models and as the detection of high-order...

reading abilities were selected to undergo fMRI scan- ning. Their brain activation profiles were assessed while they were performing a rhyme judgment task. Phonology is crucial in language acquisition because phonological information maps onto higher levels of language processing such as reading [4] ....
In addition, iCAPs overlap not only spatially, but also temporally when back-projected to their sustained-activity-inducing signals. The total activity of all the iCAPs exceeds three times the duration of the resting-state scan, however, overlapping iCAPs do not co-occur in every possible ...
scan. No statistically significant changes were detected under the Crave Condition when comparing the abstinent and non-abstinent subgroups, but also when comparing baseline and 5-week brain activation patterns in each group individually. This is an unexpected finding in light of the clinical ...

Finally, we asked whether our task elicited spontaneous replay of image sequences in object-selective brain areas during rest after the task. Based on the above findings, we reasoned that potentially reactivated sequences should become apparent in a frequency spectrum analysis. We therefore applied ...
