What are Gamma Brain Waves? How do they affect your cognition and memory?

Did you know that your brain doesn't just sit there when you're sleeping? When you think, when you focus on something, when you try to remember something old, all this time there's a lot of amazing work going on inside your brain. While doing this work, brain cells are constantly communicating with each other. This communication creates certain patterns or waves. That's what we call "brain waves." Gamma waves are a special type of wave that your brain makes.

So, today we'll simply talk about these gamma waves and the benefits they can provide you.

Let's first see what these brain waves mean.

Simply put, our brain is made up of millions of tiny cells called neurons. When you use your brain to do something, these neurons communicate with each other through tiny electrical signals. Like electricity . The rhythm that these electrical signals create is what we call brain waves.

There are special tests to measure these brain waves. You may have heard of them. The most common test is called an ``Electroencephalography`` or ``EEG`` for short. This involves attaching small sensors to the head and recording the brain's activity , that is, the electrical wave patterns.

What are the main types of brain waves?

An `EEG` test measures these waves by their speed. That is, by the number of cycles per second. We use a unit called `Hertz` (Hz). So, according to this, our brain waves can be very fast or very slow.

Imagine a time when you are wide awake and working with attention. At that time, the brain is very active. Then fast brain waves are produced. But when you are sleepy, or when you are very bored, your brain waves are slow . In this way, there are several main types, from the slowest waves to the fastest waves. Let's look at them in a table, then it will be easier to understand.

A little more about Gamma Brain Waves

Now you probably understand that gamma waves are the highest frequency, meaning they have the fastest speed, of all other types of waves. These are directly related to our higher-level thinking ability and attention.

Depending on the level of gamma waves in your brain, you may experience different effects.

• If your gamma wave level is high: You are likely to be a very happy person, able to grasp things quickly . Your intelligence level, that is, your `IQ`, may also increase, and your ability to concentrate may increase.
• If your gamma wave levels are low: You may have problems with learning and memory . There may be things like lack of attention, decreased mental abilities. Sometimes, learning disabilities and even some mental illnesses have been found to be affected by this low gamma wave level.

What benefits do we get from gamma waves?

Gamma waves are directly linked to our higher-level brain activity, namely cognition and memory. A recent study has even shown that gamma waves can improve our working memory.

Research has also shown that increasing gamma wave activity in the brain helps you achieve peak levels of focus . These gamma waves also contribute to the heightened levels of mindfulness and increased brain activity that occur during meditation.

Because of these advantages, gamma waves can do many things:

• Improves your thinking and problem-solving skills.
• It helps you process information quickly.
• It increases your memory power.
• It increases the time you can stay focused.
• Helps to stay mindful and aware.
• It can boost immunity and brain function.

Because of these effects, researchers are even exploring the possibility of using gamma waves to treat certain medical conditions. For example:

• Alzheimer's disease
Schizophrenia-emotional `(Schizophrenia)`
• Mild traumatic brain injury
• Epilepsy
• Stroke
• Attention deficit hyperactivity disorder (ADHD)
• Mood disorders like depression

But remember, these are still in the research stage. If you have any doubts about any of these symptoms, you should definitely see your doctor and talk about it.

Can you increase gamma waves in the brain?

Yes, through certain methods, we can stimulate, that is, increase, the production of these brain waves, especially gamma waves.

Meditation

Various meditation techniques and breathing exercises have been found to increase the production of gamma waves in your brain. Mindfulness meditation techniques in particular are very helpful in this.

Diet

Certain foods can also affect this. For example, studies show that eating nuts like pistachios can increase gamma waves, and peanuts can increase delta waves.

Music

Auditory stimuli, like music, can also change our brain waves. Listening to specific sound patterns like ``binaural beats'' has been found to increase alpha and theta waves. Also, listening to music that you like and that calms you down can have a positive effect on the brain.
