Meditation and exposure to auditory mantra are increasingly being acknowledged for their ability to modulate neural activity and promote relaxation, particularly during pregnancy—a period marked by heightened emotional and physiological sensitivity. This EEG study looked at 43 pregnant women with their eyes closed in three different states: resting state (RS), while listening to a mantra (M),...

Meditation has increasingly been recognized as a helpful non-pharmacological intervention to treat psychological stress, anxiety, and depression during pregnancy-a period that plays a significant role in maternal and fetal health. Although very popular, there is very little scientific evidence on how brief audio meditation affects brain activity in pregnant women. This work reports an EEG-based...

Studying EEG oscillations has attracted significant attention due to their potential impact on physiological, cognitive, psychomotor, and psycho-emotional aspects of human life. However, there is no consensus on what constitutes “EEG activity” or which indices best characterize it, particularly in the context of relaxation brought about by mantras, yoga, and meditation. This review provides a...

Electroencephalography (EEG) is a popular non-invasive method for studying brain dynamics because of its excellent temporal resolution. However, the non-stationarity, intersubject variability and class imbalance of EEG data, make it difficult to automatically discriminate between brain states that correspond to various cognitive or sensory circumstances. With the use of a deep hybrid...

Stress is a major problem in today's culture, especially for expectant mothers. Newer therapies that show promising avenues for the reduction of stress include sound therapy, yoga, mantra chanting, and meditation (M). Electroencephalography (EEG) electroencephalography plays an important role in understanding the relaxation effects caused by these practices. This study looks at the immediate...

Purpose: Electroencephalography (EEG) is a widely used non-invasive method to explore brain activity and cognitive states, including the effects of meditation. The potential of prenatal EEG to understand the neural mechanisms underlying maternal brain activity makes it an exciting field of study. However, research on prenatal EEG during different stages of meditation is currently lacking....

Meditation has been widely used to enhance cognitive health, particularly during pregnancy. θ-power, associated with cognitive processes such as attention and relaxation, is often prominent in the frontal region, which plays a critical role in executive functions and emotional regulation. This study investigated the effects of brief meditation on θ-power using EEG data from the PEM-43 dataset....

Objectives: Mantra chanting a spiritual form of meditation helps to calm the human brain. Mantra chanting is a meditative practice known to influence brainwave activities that are linked to increased theta and alpha brain rhythms. This paper investigates the variations in Power Spectral Density of experienced Mantra chanting individuals and evaluates the paired t-test before and during mantra...

Prenatal women's mental condition found among various women in this modernized world, poses as one of the great public health issues because it significantly impacts maternal and fetal health. Since mental states might be one of the aspects affecting activities in the brain, researchers have proved that alpha frequency has particularly impacted it because this particular stage is linked with...
