Abstract

Social phobia (or "social anxiety disorder") is a prevalent condition that has been the subject of increased scrutiny in recent years. The purpose of this paper is to review the neurobiology of social phobia. It is apparent from the extant literature that this disorder is poorly understood from a neurobiological perspective. There are nonetheless a number of clinical and preclinical observations which, at times, converge to illuminate areas worthy of further study. Included in this category are suggestive findings of central serotonergic dysregulation in social phobia, response to serotonin reuptake inhibitors in social phobia, and the role of serotonergic function in septohippocampal models of anxiety. Abnormalities in central dopaminergic function are also posited, supported to some extent by recent neuroimaging findings. There are in addition a number of animal and human behavioral models in existence that may be relevant to the study of social phobia. Included in this category are models of social dominance in wild baboons, social affiliation in the prairie vole, and behavioral inhibition to the unfamiliar in childhood. Newer technologies that are likely to play a major role in the delineation of the neural circuitry (e.g., functional magnetic resonance imaging) and heritability (e.g., molecular genetics) of social phobia are discussed. Finally, an interactive role for biology and experience in the expression of social phobia is considered.
