Parasites and behaviour: an ethopharmacological perspective.

Ethopharmacology combines an ethological approach to the understanding of the causes and functions of behaviour with pharmacological analysis of the underlying neuromodulatory mechanisms. Recently, this approach has been applied to the analysis of the responses of animals to parasitized individuals and to the effects of parasites on various host behaviours (eg. host defences, mate responses) and their neurobiological correlates. Martin Kavaliers, Douglas Colwell and Elena Choleris explain here how ethopharmacology can be used to address the mechanisms that underlie the often subtle effects of parasites on host behaviour.
