What are the brain waves?
The brain is made of billions of neurons and all these neurons communicate with each other. An electric activity results from this communication can express some actions and the state of the brain. This neuronal activity gives rise to voltage fluctuation across the brain areas, these fluctuations are known as โneuronal oscillationsโ or โbrain wavesโ. The number of brain waves per second is called โbrain wave frequencyโ.
The brain waves are measured and detected by using a technique called electroencephalography, or EEG. An electroencephalogram is a test that measures and records electrical activity in the brain. A trained EEG technologist attaches small electrodes to your scalp that connect to the EEG machine. The activity of your brain cells shows up as wavy lines as it's recorded. EEG results are helpful in diagnosing epilepsy and other neurological disorders and brain injuries.
When you are active and alert the brain waves result in a higher activity and higher frequency. In contrast, being sleepy and inactive results in low frequency.
Using the power spectrum analysis of EEG, the neuronal oscillations fluctuate between two values; from very slow (1,000 Hz) oscillations.
Now we are going to dive into some brain wave characteristics:
Delta - ฮด: Its frequency is about 1 - 4 Hz. Delta waves are the slowest recorded brain waves in human beings. They are found most often in infants and young children and are associated with the deepest levels of relaxation and restorative, healing sleep. Delta is prominently seen in brain injuries, learning problems, inability to think, and severe ADHD.
Theta - ฮธ: Its frequency is about 4 - 10 Hz and is classed as a โslowโ activity. It is seen in connection with creativity, intuition, daydreaming, and fantasizing and is a repository for memories, emotions, and sensations. Theta waves are strong during internal focus, meditation, prayer, and spiritual awareness.
Alpha - ฮฑ: Its frequency is about 8 - 12 Hz, Alpha waves are also present when a person is awake and relaxing, such as with the eyes closed or during meditation. Alpha wave production is associated with states of creativity, but they tend to disappear when a person performs mental activity requiring greater attention.
Beta - ฮฒ: Its frequency is about 12 - 30 Hz, Beta waves are characteristics of a strongly engaged mind. A person in active conversation would be in beta. A debater would be in high beta. A person making a speech, a teacher, or a talk show host would all be in beta when they are engaged in their work.
Gamma - ฮณ: Its frequency is about >30 Hz, Gamma brain waves are the fastest brain waves produced inside your brain. Although they can be hard to measure accurately, they tend to measure above 35 Hz and can oscillate as fast as 100 Hz. Your brain tends to produce gamma waves when you're intensely focused or actively engaged in solving a problem
As research in this field continues to advance, we can look forward to deeper insights into the intricacies of brain waves and their impact on our daily lives. Whether we are seeking relaxation, creativity, or intense focus, the study of brain waves illuminates the remarkable complexity of the human mind.
