چکیده مقاله :
هدف اصلی این پژوهش بررسی، مطالعه و مقایسه تغییرات مولفه های سیگنال و پتانسیل های برانگیخته مغزی در دو گروه حافظین و غیر حافظین قرآن در حین اجرای آزمون حافظه تصویری PRM نرم افزار کنتب و همچنین اثرات حفظ قرآن بر روی میزان آرامش،صبر،تمرکز و توجه این دو گروه می باشد،در این پژوهش داده های EEG دو گروه 15 نفره حافظین و غیر حافظین قرآن ثبت و سپس از روی 48 قطعه سیگنال مغزی به کمک روش متوسط گیری سیگنال ها ERP استخراج گردید و از روی انرژی سیگنال های ERP مپ مغزی ترسیم و ویژگی،کانال های مناسب به کمک روش T-TEST انتخاب و مقایسه بین پارامترهای واریانس،آنتروپی، توان مولفه های فرکانس پایین،نسبت توان مولفه های فرکانس پایین به بالا و نسبت توان مولفه های باند به بتا در این دو گروه صورت گرفت.نتایج بدست آمده بوضوح نشان دهنده افزایش تاخیر در زمان پاسخ دهی و افزایش درصد پاسخ های صحیح در گروه حافظین بود که این مساله نمایانگر صبر و تمرکز بیشتر این گروه و تاخیر بیشتر در عکس العمل در هنگام انتخاب پاسخ صحیح بود، از طرفی در مپ مغزی ترسیم شده در گروه حافظین نواحی فرونتال،پریتال و اکسی پیتال درگیر با شبکه توجهی و حافظه تصویری در گروه حافظین دارای اختلاف معناداری بود.
The main purpose of this research is to investigate, study and compare the changes in the signal components and brain evoked potentials in two groups of memorizers and non-memorizers of the Qur'an during the implementation of the visual memory test PRM of Kontab software and also the effects of memorizing the Qur'an on the level of relaxation, patience, concentration and The focus is on these two groups. In this research, the EEG data of two groups of 15 memorizers and non-memorizers of the Qur'an were recorded and then extracted from 48 pieces of brain signals using ERP signal averaging method, and a brain map was created from the energy of ERP signals. Delineation and characteristics of suitable channels using T-TEST method were used to select and compare the parameters of variance, entropy, power of low frequency components, power ratio of low to high frequency components and power ratio of band to beta components in these two groups.The obtained results clearly showed an increase in the delay in response time and an increase in the percentage of correct answers in the memorization group, which indicated the greater patience and concentration of this group and a greater delay in the reaction when choosing the correct answer, on the other hand, in the brain map It was drawn in the memorizing group, the frontal, parietal and occipital areas involved with the attention network and visual memory had a significant difference in the memorizing group.
