Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, IPA: [ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf] ⓘ; 26 September [O.S. 14 September] 1849 – 27 February 1936) [2] was a Russian and Soviet experimental neurologist and physiologist known for his discovery of classical conditioning through his experiments with dogs.
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
The experiments start with a dog's heart, attached to a set of tubes to serve as substitutes for the great vessels. Using a system to supply it with blood, the heart beats in the same manner as if it were inside a living organism. The film then shows a lung in a tray, which is operated by bellows that oxygenate the blood being sent to the heart ...
Ivan Pavlov's dog experiment is a well-known experiment that illustrates these terms. The unconditioned stimulus is the dog's food that would naturally cause salivation, which is an unconditioned response. Pavlov then trained the dog by ringing the bell every time before food.
Ivan Pavlov (Russian: Академик Иван Павлов, romanized: Akademik Ivan Pavlov) is a 1949 Soviet biopic directed by Grigori Roshal and starring Aleksandr Borisov, Nina Alisova and Nikolai Plotnikov. The film portrays the life of the Russian scientist Ivan Pavlov (1849–1936), known for his Pavlov's dog experiments.
Pavlov's Dog is classical conditioning, originally experiments using dogs by the Russian physiologist Ivan Pavlov. In 1904, Pavlov was awarded the Nobel Prize for his physiology work. Pavlov's Dog may also refer to: Pavlov's Dog (band), an American band "Pavlov's Dogs", a song by Rorschach "Pavlov's Dawgs", an album by German thrash metal band ...
Though Zeliony was still officially an employee of the state-run laboratory under Pavlov's leadership, in 1921, he attempted to found his own institute for the study of animal behaviour. Zeliony's proposal to secure funding for his project from the government was criticized by Pavlov and rejected (Todes 1998: 38–39). [11]

The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.
