Stress is an enormous concern in our culture because it is the root cause of many health issues. Yoga asanas and mindfulness-based practices are becoming increasingly popular for stress management; nevertheless, the biological effect of these practices on stress reactivity is still a research domain. The purpose of this review is to emphasize various biosignals that reflect stress reduction through various yoga-based practices. A comprehensive synthesis of numerous prior investigations in the existing literature was conducted. These investigations undertook a thorough examination of numerous biosignals. Various features are extracted from these signals, which are further explored to reflect the effectiveness of yoga practice in stress reduction. The multifaceted character of stress and the extensive research undertaken in this field indicate that the proposed approach would rely on multiple modalities. The notable growth of the body of literature pertaining to prospective yoga processes is deserving of attention; nonetheless, there exists a scarcity of research undertaken on these mechanisms. Hence, it is recommended that future studies adopt more stringent yoga methods and ensure the incorporation of suitable participant cohorts.

Recent research has shown that the complex and dynamic behaviour of isolated regions is necessary for the proper functioning of the human brain. To this end, network neuroscience evaluates the neural channels that respond to diverse motor tasks and assesses the brain’s functionality. However, the utilization of network neuroscience has not been done to map out the cortical sources in lower limb amputee’s postural control. Our earlier research shows that transfemoral amputees’ fronto-central region and secondary somatosensory cortex have substantial functional connections while they are balancing with vibrotactile feedback. In this work, we advanced to investigate the cortical sources of transfemoral amputee’s postural stability improvement with vibrotactile feedback. The results highlight the predominance of cortical sources in frontal and parietal lobe in alpha frequency band. The observation shows the connectivity of left superiorparietal, lateralorbitofrontal and right rostranteriorcingulate, supramarginal, and inferiorparietal sources. Moreover, the node strength of these cortical sources significantly changes (p<0.05, ANOVA) with the effect of feedback and visual input. In future, it could be interesting to develop some neural feedback techniques intended to improve the postural performance of lower limb amputees by making these cortical sources more adaptable via local stimulation techniques.
