In the field of cognitive neuroscience, meditation is receiving increasing attention and research because of its ability to regulate neural areas related to attention, emotion, and consciousness. Much evidence indicate that the meditation process is accompanied by systematic changes in neural activity, especially concentrated in the alpha (8–13 Hz), theta (4–8 Hz), and gamma (30–100 Hz)...

Ketamine is a traditional anesthetic, which has attracted much attention in recent years for its rapid antidepressant effect. It has performed particularly well in the treatment of patients with intractable depression, marking major breakthrough in the area of mental illness treatment. However, with further research, its potential neurotoxicity has gradually emerged, especially in the case of...

Meditative states provide a unique window into intrinsic neural activity, yet the spectral and spatial dynamics of resting-state EEG during meditation remain incompletely understood. This study examined how gender, age, and meditation experience influence EEG band power and spatial coherence during eyes-closed meditation. Twenty-four participants (12 experienced meditators, 12 novices)...

Lucid dreaming, the experience of being aware of dreaming in the dream, offers a unique window for neuroscientific research. In the last 50 years, the study of lucid dreaming has developed rapidly due to the advances in neuroscience, especially polysomnography and fMRI. This review highlights the neuroscientific basis of lucid dreaming about distinct neural features, varying from brain...

The increasing proportion of the population that is aged presents healthcare with the challenge of providing effective pain management for patients from a variety of cultural backgrounds. Mindfulness-based interventions (MBIs) have demonstrated efficacy in the alleviation of pain. However, there is limit research on how different ethnic groups view and benefit from them. The paper seeks to...

With the development of quantum mechanics, it is applied to different fields, including biology. As intricate as human brains, quantum physics is replacing classical physics in explaining consciousness-related brain functions. The bilayer phospholipid membrane enables neurons in the brain to store and protect quantum information, and the abundance of 1/2-spin phosphorous creates potential for...
