Theta-frequencies are measurable during deep relaxation and light sleep with active subconsciousness. At this phase the soul is open and ready to accept stimuli, which may influence its brainwaves and which may reach its subconsciousness. The individual is just ready to get up or relaxes without getting asleep. Alpha-frequencies cover waves from 8 to 12 Hz. Alpha-frequenciesīrainwaves coming up during the transition period of sleep or slight relaxation are scaled somewhat lower. Brainwaves of someone working without stress cover the frequency band between 12 to 15 Hz, humans being stressed produce brainwaves at 21 to 38 Hz. The more concentrated a human works the higher the beta-frequency rises. Beta-frequenciesīrainwaves, which are created by stimulus outside the body at the conscious phase of an individual, are called beta-frequencies. If you have ever had a moment of feeling profoundly blessed, spiritually connected, or deeply blissful, you may have reached a Gamma brainwave experience. During Gamma brainwave activity, multiple areas of the brain process information simultaneously.Īchieving Gamma waves requires a calm and quiet mind, something you can learn to achieve by using Alpha and Theta frequencies. Gamma brainwaves are at the other end of the electromagnetic spectrum from Delta waves and are among the highest frequency brainwave states, occurring at 30 Hz and above. By changing our brainwaves, we can improve our mood, elevate or lower our level of arousal and energy, control our emotional state, and even affect how we feel physically. Using specially crafted brainwave music and other techniques, we can intentionally influence and stimulate specific brainwave states using these acoustic or visual stimuli. Brainwave frequencies control all of our conscious and unconscious actions, thoughts, and feelings. However, one brainwave frequency will typically dominate, depending on what a person is doing and their state of consciousness. Our brains can produce more than one frequency at a time when we are doing or thinking about multiple things at once. Brainwaves are measured with a machine called an Electroencephalograph (EEG). Like radio waves, brainwaves are measured by their frequency, or how much they oscillate up and down every cycle. These impulses create electrical oscillations, or wave patterns, within the brain called brainwaves. Neurons communicate with each other by electric impulses. Neurons are the cells that interconnect the structures inside the brain. For example, the left hemisphere mainly controls our rational thoughts, while the right hemisphere is responsible for our intuition, emotions, and creativity. Each hemisphere is responsible for specific functions. The two hemispheres of the cerebrum are connected by the corpus callosum, a thick nerve fiber. These two halves are called brain hemispheres. The cerebrum and cerebellum are divided into two halves, one on each side of the body.
Brain scientists have also discovered many other smaller structures inside the brain, each one controlling specific functions in the brain and body. These parts are called the cerebrum, cerebellum, diencephalon, and brainstem. The human brain contains four parts that are visible by looking at a brain with unaided eyes.
