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.
Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdomen, where it contributes to the innervation of the viscera, reaching all the way to the colon.
Vagusstoff transmitted inhibition from the vagus nerves, and Acceleransstoff transmitted stimulation from the sympathetic nerves to the heart. [31] Loewi took some years to commit himself with respect to the nature of the Stoffe , but in 1926 he was sure that Vagusstoff was acetylcholine, writing in 1936 [ 32 ] "I no longer hesitate to identify ...
World Tour, recently did an X Spaces chat where she addressed rumors that she’s been using the medication to lose weight. In it, the 24-year-old made it clear she’s not here for the speculation.

In fact, a study in The Journal of Sexual Medicine found that nipple stimulation is arousing for 52% of men—yet only 17% of men have had their nipples played with during sex. Clearly, there’s ...
The classifications of substances as performance-enhancing substances are not entirely clear-cut and objective. As in other types of categorization, certain prototype performance enhancers are universally classified as such (like anabolic steroids), whereas other substances (like vitamins and protein supplements) are virtually never classified as performance enhancers despite their effects on ...
He was taller than his father by age 8, and in elementary school a special desk was made for him. He was involved in a school German and Camera club before his graduation.
