![]() ![]() Some research has been done on the increase in alpha waves during successful memory tasks. Below are a few things we have learned so far about alpha brain waves and their effects. Research on how alpha waves work continues from year to year, increasing our knowledge and helping us find applications for what we learn. Benefits Of Alpha Brain WavesĪlpha brain waves are usually associated with several different strengths of a healthy and highly functional brain. ![]() The EEG can have added benefits, including being cost-effective and highly accurate for monitoring the electrical activity of the brain. However, it is the EEG that typically tells your doctor most directly about the brain waves themselves. The fMRI measures blood flow, which is thought to increase with increased brain activity. The MEG measures the magnetic fields generated within the brain by the activity of the neurons. These are the electroencephalogram (EEG), the magnetoencephalogram (MEG), and functional magnetic resonance imaging (fMRI). Medical Tests That Reveal Brain Wave TypesĬurrently, brain activity can be measured by three different medical tests. Gamma waves generally happen when you experience a sudden insight. Delta waves tend to be dominant during deep sleep. Theta waves can increase when you’re sleeping or during hypnosis. ![]() Alpha waves are typically dominant when you’re in a relaxed and calm state of mind. Beta waves can be thought of as the waves of consciousness and reasoning. The frequencies of each of these types of brain waves are measured in cycles per second, or Hertz, as follows:Įach of these brain waves generally has a specific function. While different types of brain waves can be present in your brain simultaneously, one type of wave typically dominates the brain activity at any given time. Scientists have identified at least five types of brain waves: beta waves, alpha waves, theta waves, delta waves, and gamma waves. Five Types Of Brain Waves And Their Frequencies ![]()
