question:
The first real progress toward a modern understanding of nervous function, though, came from the investigations of Luigi Galvani, who discovered that a shock of static electricity applied to an exposed nerve of a dead frog could cause its leg to contract. Since that time, each major advance in understanding has followed more or less directly from the development of a new technique of investigation. Until the early years of the 20th century, the most important advances were derived from new methods for staining cells. Particularly critical was the invention of the Golgi stain, which (when correctly used) stains only a small fraction of neurons, but stains them in their entirety, including cell body, dendrites, and axon. Without such a stain, brain tissue under a microscope appears as an impenetrable tangle of protoplasmic fibers, in which it is impossible to determine any structure. In the hands of Camillo Golgi, and especially of the Spanish neuroanatomist Santiago Ramón y Cajal, the new stain revealed hundreds of distinct types of neurons, each with its own unique dendritic structure and pattern of connectivity.
answer:
Who found out that a shock of electricity to an exposed nerve of a dead frog caused contractions?


question:
Kerry is a Roman Catholic, and is said to carry a religious rosary, a prayer book, and a St. Christopher medal (the patron saint of travelers) when he campaigned. While Kerry is personally against abortion, he supports a woman's legal right to have one. Discussing his faith, Kerry said, "I thought of being a priest. I was very religious while at school in Switzerland. I was an altar boy and prayed all the time. I was very centered around the Mass and the church." He also said that the Letters of Paul (Apostle Paul) moved him the most, stating that they taught him to "not feel sorry for myself."
