Animal Bioethics is an important reference work for students of biomedicine and related fields, scientific researchers, and members of organizations for the protection of animal rights and welfare. The philosophical background of monistic and dualistic concepts of the human-animal relationship is considered in detail. Experimental models in drug development and pain testing are analyzed, and the translational aspect of in vivo experiments discussed. One chapter is dedicated to neuroethics, taking into account the importance of animal experiments for examining brain function. Finally, an overview of modern legislation related to animal experiments is given, the ethical basis of the principles of Good Laboratory Practice is assessed, and the importance of animal bioethics for writing scientific projects is shown.
