The researchers found that constant reflection alters communication between relay channels that capture data from the sensory world to the cerebral cortex of the brain. It allows one to easily change into a state of deep meditation, making meditation easier. Meditation has been a pillar of Indian culture for years. However, scientific understanding of the various forms of yoga is limited. Most EEG studies have found that deep meditation leads to an increase in theta and delta waves in the brain. These waves are caused during leisure time but not on the sleeping stage.
A new study supported by the SATYAM program of the Department of Science and Technology (DST) suggests that consistent activity reduces thalamocortical connections with brain regions. The findings were presented at the Annual Meeting of the International Organization for Magnetic Resonance. A team comprising Vaibhav Tripathi, Anju Dhawan, Vidur Mahajan, and Rahul Garg recorded brain activity with the help of MRI of meditation practitioners and those who did not practice meditation before, during, and after meditation.
The research results were co-produced by the Department of Psychiatry and Psychiatry, Boston University, School of Information Technology, Indian Institute of Technology, Delhi, Mahajan Imaging Center, Delhi, and Department of Psychiatry, All India Institute of Medical Science, Delhi demonstrated and validated psychological testing of Pratyahara and Dharana associated with the withdrawal of sensory information that allowed a decrease in brain activity that helped to transition to deeper levels of meditation. He emphasized the importance of different strategies that include the features of Pratyahara and Dharana.
A weak effect has been observed in all novices, although it is not as strong as meditators who suggest that the one-time meditation effect is good, but a consistent practice results in long-term changes and makes it easier to meditate. Although MRI allows for unprecedented spatial fixation of the brain, it is slower compared to EEG, which is a better representative of neuronal shooting in the brain but without localized coverage. In future studies, researchers planned to simultaneously record EEG / MRI activity to detect brain waves during brain duration and to better reflect spatiotemporal flexibility of meditation in all the different provinces of Dhyana and Samadhi.
