Vagusstoff (literally translated from German as "Vagus Substance") refers to the substance released by stimulation of the vagus nerve which causes a reduction in the heart rate. Discovered in 1921 by physiologist Otto Loewi , vagusstoff was the first confirmation of chemical synaptic transmission and the first neurotransmitter ever discovered.
His experiment was iconic because it was the first to demonstrate the endogenous release of a chemical substance that could cause a response in the absence of electrical stimulation. It paved the way for the understanding that the electrical signaling event (action potential) causes a chemical event (release of neurotransmitter from synapses ...
The experiment became a popular way to illustrate the principles of air pressure, and many smaller copies of the hemispheres were made, and are used to this day in science classes. Reenactments of von Guericke's experiment of 1654 are performed in locations around the world by the Otto von Guericke Society.
[29] [30] [31] The first experiment was a replica of Nuttin's 1987 study of letter preference, looking for an effect tied to letters of the participant's name. [ 32 ] [ 33 ] The second experiment involved numbers, looking for an effect tied to numbers representing the day of the month a participant was born (between 1 and 31) and the month of ...

Emoto claimed that water was a "blueprint for our reality" and that emotional "energies" and "vibrations" could change its physical structure. [14] His water crystal experiments consisted of exposing water in glasses to various words, pictures, or music, then freezing it and examining the ice crystals' aesthetic properties with microscopic photography.
