Brain’s wiring and signal speed shape alpha waves and background activity across the lifespan

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.

Russian researchers present ultra-precise brain imaging tool

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.

New findings on how the brain ignores distractions

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.

A neural basis for benefits of meditation

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.
