Mechanism of unilateral spatial neglect after stroke based on functional magnetic resonance imaging technique / 实用医学杂志

ABSTRACT

Objective To explore the mechanism of brain function connection (FC) by observing the changes of unilateral spatial neglect (USN) and non-USN patients, using functional magnetic resonance imaging technique (fMRI). Methods 8 USN and 8 control patients participated in the study and fMRI data were collected. The data was analyzed by independent component analysis method. Results USN group showed increased FC in the left frontal/temporal lobeas well and decreased FC in the right cingulate gyrus, precuneus, temporalgyrus compared with control group. These were highly related to behavioral scores. Conclusions Abnormal brain function connection may be related to USN. The findings were helpful for understanding the potential mechanism underlying of USN.
