Abstract
Dogs can be used as research models in order to contribute to a better understanding of human neuropsychiatric disorders and to explore treatment options. In general, smaller laboratory animals, most often mice and rats, have been extensively used. Nevertheless, the implementation of larger animal (e.g. dogs) models has several important advantages. Their larger brain size omits the need for dedicated equipment (micro-PET or micro-SPECT) and the larger portion of the frontal cortex (crucial to behaviour regulation) in particular allows superior investigation of this area. They can further be used to investigate normal physiology and interaction of several neurotransmitter systems and the effects of drugs on brain function and chemistry. In this regard, they can also be used to obtain information on the pharmacokinetics and pharmacodynamics of newly developed drugs and the dosage at which maximal response and least side effects occur. Finally, natural animal behavioural models of disorders can be used to enlighten the biological base of several human neuropsychiatric disorders. In this chapter, an overview will be given on the use of functional brain imaging in dogs suffering from impulsive aggression.
