29 de abr. de 2024 · OTTO LOEWI. 1857-1952. la «función integradora del sistema nervioso», en cuyo desarrollo se compendian sus importantes aportaciones al estudio de la diferenciación entre acciones inhibidoras y acciones excitadoras. Charles Sherrington. SIGLO XX. 1852-1934
Hace 6 días · In 1921 Otto Loewi demonstrated the release of acetylcholine (ACh) from vagus nerve terminals in frog hearts. Henry Dale extended Loewi's work on ACh, later sharing the Nobel Prize with Loewi. In 1946 Ulf von Euler reported further work on adrenergic transmission.
27 de abr. de 2024 · In 1921, Otto Loewi demonstrated that stimulation of the vagus nerve terminals in frog hearts released “vagustoff,” which was later shown to be ACh. Dale and Loewi later shared the Nobel Prize in 1946.
4 de may. de 2024 · In the 1920s, however, Otto Loewi discovered that the chemical compound acetylcholine (ACh) conveys signals from the vagus nerve to the heart. Loewi's discovery provoked considerable debate in the 1930s over whether chemical signaling existed at other synapses, including synapses between motor nerve and skeletal muscle as well as ...
5 de may. de 2024 · Upon completion of this experiment, Loewi asserted that sympathetic regulation of cardiac function can be mediated through changes in chemical concentrations. Furthermore, Otto Loewi is credited with discovering acetylcholine (ACh) – the first known neurotransmitter.
22 de abr. de 2024 · The Nobel Prize was awarded to Sir Henry Dale and Otto Loewi in 1936 for their groundbreaking discovery of chemical transmission of the effects of nerve impulses. At present, ACh is a well known classic neurotransmitter in the central and peripheral cholinergic systems.
22 de abr. de 2024 · Otto Loewi (* 3. Juni 1873 in Frankfurt am Main; † 25. Dezember 1961 in New York) war ein deutsch/österreichisch-amerikanischer Pharmakologe. Für ihre Entdeckungen bei der chemischen Übertragung der Nervenimpulse erhielten er und Henry H. Dale 1936 den Nobelpreis für Medizin.
