Introduction. The neurobiology of social recognition, attraction and bonding
Providing an understanding of the neural, humoral and genetic factors that control social recognition and attraction, communication andinterpretation of emotional state and the formation of long-term emotional bonds is of key importance for human mental health and well-being. However, unlocking the secrets of these different aspects of the social brain presents a significant challenge to Neuroscience, since a broad spectrum of different behaviours and brain systems are involved together with a multitude of complex interactions betweenthem. The question also arises as to whether true insights into the workings of the human social brain can be gained from detailed studies of other mammalian species that have evolved a variety of different social systems. Advances in human brain imaging have provided us with far more detailed information about both social and emotional recognition pathways in the brain. We also are beginning tounderstand the substrates involved in romantic attraction and social bonds. Comparing this with the more extensive research that has often been carried out on other mammalian species strongly suggests extensive evolutionary conservation of many of the basic mechanisms operating within the social brain that regulate discrimination of individual identity, interpretation of emotion cues and even mateattraction. The main aim of this theme issue has been to try to bring together the major advances made in recent years in diverse areas of research on both humans and other mammalian species investigating the neurobiology of social recognition, attraction and bonding. Numerous conferences and symposia have focused on specific features of social recognition, such as identifying individuals viaodours or voices or faces, although research findings from the different senses are rarely presented together. Similarly, studies investigating the processes by which individuals recognize one another are often considered separately from those investigating communication and interpretation of emotional cues. Yet again, studies investigating these identity and emotion recognition cues often do not linkinto those investigating the specific cues that determine sexual or social attraction and can lead to the establishment of social bonds. A number of the papers in this issue detail the present state of knowledge on the best understood area of social identity recognition in mammals, namely olfaction. The first provides a review of the nature of mammalian social chemo signals and the odorant receptors,neural pathways and neurochemical systems required for their detection by both the vomeronasal and main olfactory
