ISN is a scholarly society devoted to neuroethology: the study of how nervous systems generate natural behaviour in animals.
"The intent is to bring together neuroscientists and ethologists to advance our understanding of the neural basis of behaviour in animals, whether they be vertebrates or invertebrates. There is an intrinsic interest in explaining the huge range of behaviour shown by many different sorts of animals, but also in exploiting this diversity to illuminate basic principals of the organisation and design of brains in general. A continuing driving force is therefore the expectation that the study of neural mechanisms underlying a specific behaviour in a particular animal will elucidate mechanisms that are more generally applicable. Thus the specializations of owls for hearing have given insights into how sounds can be localized, the relative simplicity of the spinal cord of lampreys has told us much about the connectivity and pharmacology of neurons involved in generating locomotion, and the detailed analysis of small networks in crabs, leeches and insects continually reveal unexpected mechanisms that must be incorporated into our thinking about the functioning of more complex brains."
