Abstract

Introduction:
Emotional inhibition is one of the cognitive ability, which is important in social behavior and has critical role in quality of life. Brain lesions located in frontal lobe, especially in prefrontal area can change emotional inhibition.
The aim of this study was evaluating the role of surgery, and the effect of the existence of tumor in frontal lobe on the ability of emotional inhibition.
Method:
Sixteen patients afflicted by frontal brain lesions underwent fmri with emotional face Go/No-Go task before and three months after surgery. In addition, IVA test done to assess the response control and attention of patients in these eras.
Emotional Go/No-Go task contain two runs. Each run has four blocks with 256 emotional face images (Happy And Angry). For evaluating the emotional inhibition, ask the patients to select the specific emotion, which was showing as the instruction images at the beginning of each block for 3 seconds. The Fmri data collected and analyzed with FSL sSoftware.
Results:
The Fmri data demonstrated the larger activity in respected regions of the brain, which are responsible for emotional inhibition after surgery. Moreover, accuracy and reaction time improved in this state.
Conclusion:
According to this study, the emotional inhibition improved after surgery; So we can expect the better quality of life in these patients. The change in accuracy and reaction time was remarkably seen in happy emotion rather than angry; And seen in Low-grade gliomas.
