CHEMICAL TRANSMISSION OF NERVE IMPULSES

WebIn 1921 Otto Loewi stimulated the heart of a frog with electrical impulses and had it pump a small amount of nutrient solution. When the fluid was transferred to another heart, it operated in a similar way. This provided proof that chemical substances convey nerve signals to organs. WebIt is true that the nerve impulse itself, an “electrical” event in the sense that it is a change or polarisation propagated by local action currents, rests on chemical processes. It might also be argued that the arrangement of neurones in a brain is chemically determined since it is dependent on the individual’s protein organisation.
