Fritsch, Gustav (1838-1927) & Hitzig, Edward (1838-1907) Working in their own laboratory, two German physicians, Gustav Fritsch (1838-1927) and Edward Hitzig (1838-1907), discovered the motor cortex of the brain. Specifically, they found that electrical stimulation of particular areas resulted in muscle movement. If they stimulated a particular spot on the left side of a dog’s brain, its right leg would move.
People In Psych
Galvani, Luigi (1737-1798) Born and educated in Bolgna, Italy, Galvani is less known as a professor of anatomy than for his conclusion that animal tissue is capable of generating electricity. Using an electrically-charged scalpel, he accidentally touched the probe to the leg of a frog, causing it to twitch. Galvani did not conclude that tissue conducts electricity but that animals actually generate it themselves.
Hartley, David (1705-1757) Hartley studied at Cambridge and was prepared to follow his father’s footsteps (minister) but his interest in biology led him to seek a medical degree. He is considered to be one of the first physiological psychologists. In 1749, Hartley published a combination of psychological and theological insights entitled Observations on Man, His Frame, His Duty and His Expectations. Like Newton, Hartley dismissed Descartes’ contention that nerves are hollow. He maintained that sensations cause vibrations in the nerves which in turn cause vibrations in the brain. These vibratuncles result in ideas (faint vibrations) and memory (reactivating the original vibrations).
Gorgius (385-380 BC) Born in Sicily, Gorgias is credited with introducing cadence in prose and using everyday examples and locations in arguments. Best known as the title character of a dialogue by Plato, Gorgias answers “what is reality?” by suggesting that nothing exits. Or if it exists it can’t be known or communicated. Ironically, Gorgias made a living by teaching rhetoric (how to communicate effectively).
Bain Alexander (1818-1903)The son of a weaver, Bain was born, raised and educated in Aberdeen, Scotland. Indeed, except for several years in London, he lived whole life in Aberdeen. In 1876, Bain wrote the first journal devoted exclusively to psychology (Mind). He also provided the first books on psychology as such. Until William James wrote Principles of Psychology (1890), Bain’s books (The Senses and Emotions) were widely used as textbooks of psychology. A friend of JS Mill (who he met during his London years), Bain was an empiricist and a utilitarianist. He emphasized the law of contiguity, but differentiated between voluntary and reflexive behavior, held that people are capable of spontaneous activity which becomes increasingly purposive as it is rewarded by pleasure, and was a mind-body parallelist. He held that every sensation has both a physiological and a mental reaction. Bain is sometimes called the first modern physiological psychologist because of his detailed descriptions of sense organs and how they worked. He is best known for his description of the reflex arc.
AverroësHis full name was Abu al-Walid Muhammad ibn Ahmad ibn Muhammad ibn Rushd. Born in Cordoba, Spain, Averroës was the son a judge. He studied medicine, philosophy and Muslim law (which has both moral and legal aspects). His commentaries on Aristotle were translated into Latin and Hebrew and influenced both Hellenistic Judism and scholastic philosophy. Averroes became a judge, chief physician for the caliph of Morocco and believed that the world has no beginning and no miraculous creation. God is “prime mover” of the universe and the human soul comes from Him. Averroes emphasized both reason and revelation so much so that his opponents referred to it as “double truth.”
