Music is indispensable in many people’s lives. When waking up in the morning, the brisk mobile phone *** starts an energetic day; listening to music while working can help concentrate and relax; even before going to bed at night Listen to some music to relax your mind and get a good night's sleep. But did you know how music can reduce muscle pain, brain disease, and blood circulation throughout the body? In a TED talk in October 2017, Dr. Lee Bartel revealed the secrets of how music affects the brain and body. The concept of using music to influence brain waves

Dr. Lee Bartel recalled growing up in an apiary in Western Canada as a child. When collecting honey every summer and autumn, the honey would drip on the conveyor belt of the machine. The conveyor belt begins to produce an annoying squeaking sound due to friction. If a cricket walks into the hive at this time and starts to chirp, it won't take long for the squeaking sound on the conveyor belt to synchronize with the cricket's chirping.

Dr. Lee Bartel said, "This phenomenon has been swirling in my mind until I discovered the buzzing phenomenon in physics, which causes a rhythmic and vibrating object to produce synchronization with another object. Frequency, I started to use this natural phenomenon to make music that affects human brain waves. For example, light music with a special rhythm can help you fall asleep, help you relax, and even help you concentrate." How does sound affect human brain waves? Body cells?

After making music that affects human brain waves for many years, Dr. Lee Bartel discovered that a very low sound, a single pitch of about 40Hz (Hertz), can help people reduce pain and even reduce brain diseases, such as: Alzheimer’s, Parkinson’s, and depression. This sound can stimulate cells and reduce the risk and effects of some common health problems.

Because sound or music is actually vibration produced by the compression of molecules in the air, when the 40Hz vibration is transmitted to the ear, many hair cells in the cochlea will convert this vibration into electricity. The signal is transmitted to the neurons of the brain via the auditory nerve, where it affects thousands of neurons in the brain, affecting brain waves to become gamma brain waves. Because the measurement method of brain waves and the measurement method of sound are both Hz (hertz), and the sound of 40 or 40 Hz per second is called gamma, so it can just form gamma brain waves in the brain.

In addition, the millions of neurons in the brain do not transmit electrical signals independently. Instead, like a circuit board, many neurons are connected together to form nerve conduction. Circuits allow us to see, hear, smell, move, and form short-term and long-term memories. To carry out these tasks, the brain needs stable brain waves, which happen to be the gamma brain waves mentioned earlier.

If the brain circuits cannot work and the circuits that start and control movement are not connected properly, various brain function diseases will occur. For example: tremors in the hands and feet or immobility are symptoms of Parkinson's disease; and long-term memory circuits are not connected properly, which may cause people to suffer from dementia. Music helps treat brain diseases

When using music to help treat brain diseases, Dr. Lee Bartel mentioned the example of using music to help patients with dementia. He gave the patients three treatments a week, each treatment A special device is used to allow patients to listen to 40Hz sounds for 30 minutes. At the end of 12 weeks of treatment, the patient could more easily remember her grandson's name and her cognitive abilities had improved. Because the circuit resistance of neurons in the brains of patients with dementia increases, the electrical signal transmission of neurons can be blocked through music.

A previous study conducted by MIT pointed out that after patients with dementia stayed in a room with 40Hz light flashes, the amyloid protein in the brains of Alzheimer's killers decreased by 50%. Therefore, Dr. Lee Bartel's research team wants to compare the use of 40Hz sound therapy and light therapy in patients with Alzheimer's disease. It is hoped that sound therapy will also reduce amyloid protein and help treat Alzheimer's disease. .
