The Brain Wave Frequencies That are Measured by qEEG

When we talk about brain wave frequencies measured by qEEG (quantitative electroencephalography), we are referring to the different electrical patterns or waves that our brains produce. These waves are associated with different states of consciousness, mental activities, and emotions. Let’s go through the main brain wave frequencies:

1. Delta waves (0.5 – 4 Hz): These are the slowest brain waves and are usually seen in deep sleep or in very deep meditation. They help us rest and rejuvenate.

2. Theta waves (4 – 8 Hz): These waves are associated with a relaxed and dreamy state. They are often seen during light sleep, deep meditation, or when you are deeply focused on something.

3. Alpha waves (8 – 12 Hz): These waves occur when we are in a calm and relaxed state, but still awake. They are often seen when you close your eyes, meditate, or engage in creative activities.

4. Beta waves (12 – 30 Hz): These waves are associated with active thinking, problem-solving, and concentration. They are usually present when we are awake and engaged in activities that require mental effort.

5. Gamma waves (30 – 100 Hz): These are the fastest brain waves and are associated with high-level cognitive processes, like perception, learning, and memory. They are often seen during states of heightened awareness or deep focus.

These brain wave frequencies can be measured using qEEG, which is a non-invasive technique that involves placing electrodes on the scalp to detect and record the electrical activity of the brain. By analyzing these brain waves, scientists and doctors can gain insights into brain function, assess cognitive abilities, and diagnose certain conditions or disorders.

Remember, these brain wave frequencies are constantly changing throughout the day depending on what we are doing, feeling, or thinking. It’s like our brains have their own unique language, and qEEG helps us understand and interpret it!
