How do brain drugs such as "dopamine", "noradrenaline", "endorphin", "oxytocin" and "serotonin" occur "during sex"? Based on the science that aims to investigate the cause of the occurrence and induce it with "sound", this is a YouTube channel "Brain Acoustics Laboratory" that produces and distributes "sounds" specialized for "brain orgasms" and "aphrodisiacs". For example, when "brain orgasms" occur, the switch is theta waves of 3 to 8Hz. The active frequency of dopamine is 5Hz, the active frequency of endorphin is around 3Hz, and the brain waves during drug addiction are 25Hz, and the brain's brain is aware that the brain waves that produce and activate the neurotransmitters that give the effect of "pleasure" have been elucidated to some extent. By providing those brain waves as "sound", it is possible to forcibly induce brain waves and manipulate the faucet of brain drugs. "What is the difference between brain waves and sound waves?" Sound waves are broken down into electrical signals by hair cells in the cochlea, and the information of the waves is transmitted to the brain. This can be calculated using the Fourier transform. The principle of superposition > Decompose into the sum of sine waves. The principle of orthogonality > The mathematical formula that represents the waveform is expressed as a function. Humans go through this complex process in an instant, from the eardrum to the prefrontal cortex, until the sound reaches the consciousness. So if the necessary frequency is given, the information of that frequency will be transmitted to the brain. This means that "whether or not you are aware that you can hear it", as long as the hair cells catch the vibrations, they will generate and transmit electrical signals. This phenomenon is also related to the fact that ultra-low frequencies of environmental sounds below 20Hz disjointedly manipulate brainwaves and affect the autonomic nervous system. On the other hand, to convert brainwaves into sound, we use the Fourier transform to extract the frequency band elements, observe and convert the wave frequency and the combination of strength for each frequency, called "features." Based on this, we create "sounds" and "frequencies" that directly affect the brain, and "sounds made from brainwaves." Processed sounds coming from the human body (biological sounds) EEGs themselves or an electroencephalograph converted into sound Five typical types of brainwaves: delta waves, alpha waves, theta waves, beta waves, gamma waves Ba Using inaural and difference tones, we will introduce things that have a direct physical effect on the brain, using repeated changes in the frequency, amplitude, and sound pressure localization of wavelength waveforms, that approach the diencephalon and brain stem, that stimulate the sympathetic and parasympathetic nerves, and forcibly control the autonomic nervous system, and that further weaken the conscious mind and affect the subconscious. We will also introduce things that have a very strong approach to the brain, and can be "brain orgasm induction" and "aphrodisiac sounds." In addition to the things we use at the Brain Acoustics Laboratory, we will also introduce things that have not been released due to regulations, things we use for personal use, and mysterious things that are stored in a warehouse for some reason.
