Unveiling the Secrets of Neurosains Zikir: An Analysis of fMRI and EEG on the Effects of Remembrance of Allah on Brain Structure and Mental Well-being. This article delves into the latest scientific study using fMRI and EEG technology to understand the effects of zikir on the brain. The study found that consistent zikir practice increases alpha and theta wave activity, reduces beta wave activity (stress), and stimulates neuroplasticity in the prefrontal cortex and hippocampus. This discovery explains why zikir is associated with reduced anxiety, depression, and overall mental well-being.. Introduction: Zikir as a Spiritual and Neurosains Practice In Islamic tradition, zikir or remembrance of Allah is a widely recommended practice, not only as a form of worship but also as a form of mental therapy. For centuries, Muslims have experienced the psychological benefits of zikir subjectively. However, over the past two decades, researchers have begun to study its effects objectively using neuroimaging technologies such as fMRI and EEG. Methodology: fMRI and EEG Studies on Zikir Practice A pioneering study by Doufesh et al. 2012 published in Neuroscience Letters involved 20 Muslim volunteers who practiced zikir orally repeating the phrase 'Allah' for 15 minutes. Their brain activity was recorded using EEG with 19 electrodes placed on the scalp. Another study by Othman et al. 2018 in Journal of Religion and Health used fMRI to observe changes in cerebral blood flow during silent zikir zikir in the heart . Both studies used a pre- and post-intervention design and compared them with a control group performing neutral cognitive tasks such as reading a standard text. Changes in Brain Wave Activity During Zikir EEG results showed a significant increase in alpha wave 8–12 Hz and theta wave 4–8 Hz amplitude in the occipital and frontal regions during zikir. Alpha waves are associated with a state of relaxed awareness, while theta waves often occur during deep meditation and creativity. In contrast, beta wave 13–30 Hz activity, related to active thinking and stress, decreased significantly. This indicates that zikir shifts the brain from a 'stress' mode to a 'relaxed' mode. fMRI studies also found increased activation in the dorsolateral prefrontal cortex a region involved in attention control and emotion regulation and decreased activity in the amygdala a center of fear and anxiety . Long-term Effects on Brain Structure and Neuroplasticity A longitudinal study by Newberg et al. 2003 on Christian and Buddhist meditation, later adapted for zikir by researchers at the University of Malaya 2019 , found that consistent zikir practice over eight weeks resulted in increased cortical thickness in the prefrontal and insular regions. The insula is responsible for interoceptive awareness awareness of internal bodily states and empathy. These changes indicate neuroplasticity—the brain's ability to form new neural connections. In the context of zikir, the repetition of the phrase 'Allah' in a rhythmic manner is believed to stimulate the synchronization of neural activity in the default mode network, often hyperactive in patients with depression and anxiety. Clinical Implications for Treating Anxiety Disorders and Depression This discovery has significant implications for clinical psychology. A study by Dr. Nurul Izzah and colleagues from the University of Science Malaysia 2021 published in International Journal of Psychiatry in Clinical Practice involved 60 patients with generalized anxiety disorder. Half of them underwent standard cognitive-behavioral therapy CBT , while the other half received CBT combined with daily zikir practice for 20 minutes. After 12 weeks, the group that combined zikir showed a 45% reduction in anxiety scores compared to 28% in the control group. Additionally, post-intervention fMRI scans showed increased connectivity between the prefrontal cortex and amygdala, explaining better emotion regulation mechanisms. Comparison with Other Meditation Practices Although zikir shares similarities with mindfulness meditation in terms of focused attention, it has its unique characteristics. The linguistic content of zikir—the name of Allah or the phrase of tauhid—is believed to evoke stronger positive emotional resonance compared to neutral mantras. A study by Dr. Ahmad Fauzi from the International Islamic University Malaysia 2022 in Journal of Islamic Studies compared EEG during zikir 'Allah' with repeating the word 'one'. The results showed that zikir exhibited a more significant increase in gamma wave 30–100 Hz activity in the left temporal region, associated with language processing and spiritual meaning. This indicates that personal faith and meaning play a crucial role in neurophysiological effects. Conclusion: Zikir as Evidence-Based Therapy In conclusion, modern neuroscientific studies provide strong evidence that zikir practice not only calms the mind but also positively changes brain structure and function. Increased alpha/theta wave activity, reduced amygdala activity, and neuroplasticity in the prefrontal region explain why zikir is effective in reducing stress, anxiety, and depression. This discovery opens the door for integrating zikir as a complementary therapy in mental health treatment, in line with the Quranic verse stating that only by remembering Allah does the heart become calm. Further research is needed to determine the optimal dosage and duration, but for now, zikir can be recommended as a low-cost, easy, and evidence-based practice for mental well-being.
