Beta is generally the mental state most people are in during the day, and usually this state in itself is uneventful. However, beta brain wave activity is significant to proper mental functioning, and insufficient beta activity can cause mental or emotional disorders such as depression, ADD and insomnia.
Broadly speaking, beta brain waves are associated with alert attentiveness and concentration- intense focus and problem solving are linked to beta activity. Beta waves can also be related to strong, excited emotions.
Medications that are designed to induce concentration and alertness, such as Ritalin or Adderall, actually produce a beta brain wave state in most subjects.
All 4 of the studies highlighted in the infographic above met Dr. Tina Huang's standards for inclusion in her landmark 2008 article, "A Comprehensive Review of the Psychological Effects of Brainwave Entrainment."
To be included in that review, articles had to be original, full-length journal articles in peer-reviewed journals, and the studies had to be of an experimental design, with outcomes measured using reliable and appropriate test procedures, and with statistical outcomes revealed.
That highly selective criteria means that these studies represent only a portion of all of the work conducted in this field, but are decidedly some of the most significant. Keep reading to learn more about the incredible results of this research.
