A new model, Xi–αNET, explains how brain structure and signal conduction speed shape alpha waves and background activity. The study found that faster conduction speeds in younger individuals correspond to higher alpha frequencies, while slower conduction speeds in older adults lead to declining alpha frequencies.
Using DMT, researchers discovered that interactions with alpha waves are associated with stronger loss of sense of self. The shift away from criticality was linked to dampening of alpha waves, which may reveal how the time-extended component of self-awareness is weakened.
Researchers used a closed-loop auditory stimulation approach to target alpha rhythms in the brain, revealing that sounds at specific phases can manipulate alpha oscillations. The study's findings suggest that sound stimulation could be used to enhance cognition and sleep in people with dementia.
A team from the Russian Quantum Center developed a novel solid-state supersensitive room-temperature magnetometer capable of registering weak electrical sources in the brain. The device successfully detected alpha rhythm, a sinusoidal electric current in the back of the brain, and showed higher sensitivity than existing systems.
Researchers found that shorter delays in neurofeedback training significantly increase efficacy, enabling sustainable changes. This breakthrough opens new potential for NFB therapy in anxiety, depression, epilepsy, and other conditions.
Researchers at Brown University found that the brain uses specific patterns of brain wave synchrony to suppress attention and ignore distracting stimuli. By harnessing this process, scientists hope to develop new treatments for pain and depressive thoughts through non-invasive brain stimulation techniques.
Researchers propose that mindfulness practitioners gain enhanced control over sensory cortical alpha rhythms, enabling optimal filtering of sensory information and regulation of negative thoughts. This control is linked to the practice of mindful awareness of breath and body sensations.
A study from Massachusetts General Hospital found that mindfulness meditation enhances regulation of alpha rhythms, which 'turn down the volume' on distracting information. This improvement allows practitioners to better process new facts and regulate pain perception.
A new study from Massachusetts General Hospital reveals that alpha brain rhythm persists during sleep and signifies vulnerability to external stimuli. The findings could lead to more precise approaches to inducing and supporting sleep, with potential applications in real-time tracking of sleep states.
