Involved brain areas in processing of Persian classical music: an fMRI study

AbstractThe purpose of this study is to investigate the neurological process of the rhythm in Persian classical music by using fMRI. The test consists of two groups of no rhythmic and rhythmic pieces that has examined on 12 right-handed musicians. The result showed that no rhythmic Persian pieces activated right middle frontal gyrus, right middle temporal gyrus, left planum temporal and right superior temporal gyrus, and rhythmic pieces activated left frontal pole, left inferior frontal gyrus and left suramarginal. These results are based on the laterality and hierarchical models

on The Study of Herbal Combination Effect of Securigera Securidaca, Vaccinium Arctostaphylos, Citrullus Colocynthis and Coriandrium Sativum on Triglyceride of Pre-Diabetic Elderlies

Background: Increasing blood sugar and hyperlipidemia in could deteriorate the late complications in diabetic patients. Hence, this study aimed to evaluate the herbal combination effects of Securigera securidaca, Vaccinium Arctostaphylos, Citrullus Colocynthis and Coriandrum sativum on triglyceride level in pre-diabetic elderlies. Materials and Methods: In a single-blind randomized controlled trial study, 60 pre-diabetic individuals aged between 60 to 70 years with a triglyceride level of 180-250 mg/dl were selected. They were divided into two groups (drug and placebo) randomly. The drug group received a diet including 500 mg capsules of herbal blend once daily, and the placebo group received diet including placebo capsules (500 mg flour) in the same period. The serum triglyceride level was evaluated after 30 days in both groups. Finally, the SPSS software version 18 was used for data analysis. Results: The mean triglyceride level, between before the intervention and afterward were not significantly different, and the mean changes in triglyceride level in total showed no significant differences as well. Likewise, the comparison between the mean triglyceride level before and after the intervention, independently in drug group or placebo revealed no statically significant differences. Conclusion: There is no adequate evidence for the efficiency of this 30-day period intervention of herbal blend. Therefore it is recommended to perform further studies using different drug dosage and period of consumption to get more conclusive results about the potential effectiveness of these herbal medications on elderly’s triglyceride level

Homayoun as a Persian Music Scale on Non-Musician’s Brain: an fMRI Study

Introduction: The aim of this study was to get to a neurological evaluation of one of the Persian music scales, Homayoun, on brain activation of non-musician subjects. We selected this scale because Homayoun is one of the main scales in Persian classical music which is similar to minor mode in western scales. Methods: This study was performed on 19 right handed subjects, Aging 22-31. Here some pieces from Homayoun Dastgah are used in both rhythmic and non-rhythmic. Result: The results of this study revealed the brain activities for each of rhythmic and non-rhythmic versions of Homayoun Dastgah. The activated regions for non-rhythmic Homayoun contained: right and left Subcallosal Cortex, left Medial Frontal cortex, left anterior Cingulate Gyrus, left Frontal Pole and for rhythmic Homayoun contained: left Precentral Gyrus, left Precuneous Cortex, left anterior Supramarginal, left Superior Parietal Lobule, left Postcentral Gyrus. Also, we acquired amygdala area in both pieces of music. Discussion: Based on arousal effects of rhythm and Damasio's somatic marker hypothesis, non-rhythmic Homayoun activates regions related to emotion and thinking while activity of rhythmic Homayoun is related to areas of movement and motion
