Lektion 1
What Are Brainwaves?
A brainwave is a rhythmic pattern of electrical activity in the brain. Brainwaves are measured using an electroencephalogram (EEG), which records the electrical signals produced by the brain's neurons.
Lektion 2
Beta Brainwaves
Beta waves (12-30 Hz): These are fast brainwaves and are associated with a state of alertness, focus, and concentration. We experience beta waves when we are awake and engaged in mental activity, such as problem-solving, learning, or working.
Lektion 3
Alpha Brainwaves
Alpha waves (8-12 Hz): These brainwaves are associated with a state of relaxation and calmness. We experience alpha waves when we are daydreaming or meditating with our eyes closed.
Lektion 4
Theta Brainwaves
Theta waves (4-8 Hz): These brainwaves are associated with a state of deep relaxation and creativity. We experience theta waves when we are in a deep meditative state, or during REM sleep.
Lektion 5
Delta Brainwaves
Delta waves (0.5-4 Hz): These are the slowest brainwaves and are associated with deep sleep. We experience delta waves when we are in the deepest stages of sleep, when our body is repairing and restoring itself.
Lektion 6
Gamma Brainwaves
Gamma waves (30-100 Hz): These are the fastest brainwaves and are associated with high levels of focus, concentration, and learning. Gamma waves are also involved in processing emotions and consciousness.
