17. USE OF ANIMALS IN THE LAB • Humane Treatment • Animal Care & Use Protocols • Anesthesia • Minimize numbers through sharing • Use of computer simulations

18. USE OF ANIMALS IN THE LAB Assignment #1: Animal Care & Use Report: • Justify use of Animals in the Teaching Laboratory • Citations • In text AND full bibliography • See course web site for proper citation format & concerns regarding plagiarism • Focus on use of animals in education & teaching (NOT research!) • Spelling, grammar & organization COUNT!

21. ACADEMIC INTEGRITY • Plagiarism: • Use of another’s thoughts, ideas or words without giving proper credit. • See Plagiarism Link on web site • Future work submitted through TurnItIn.com

22. ACADEMIC INTEGRITY Plagiarism: • An Excerpt From Your Textbook: Behavior results when a signal travels from a sensory receptor, through some number of synapses in the central nervous system, and out through a motor neuron, activating skeletal muscles. Even in the simplest neuronal circuits, information coming both from other neurons in the same part of the nervous system and from neurons with somata in distant locations impinges on the circuit and can modify the behavioral output.

23. ACADEMIC INTEGRITY Plagiarism: • In Text Citations: • Behavior in animals is the result of a complex web of interconnected neurons communicating with one another (Randall et al. 2002). • A behavioral response to a stimulus often involves multiple neurons, each of which may have numerous inputs (Randall et al. 2002). • Bibliography: Randall, D., W. Burggren, and K. French. 2002. Behavior: Initiation, Patterns, and Control. pp 425 – 470 In: Animal Physiology: Mechanisms and Adaptations (J. Noe, M. Ryan, J. O’Neill & M. Kuhta, editors),W.H. Freeman and Company, New York.
