Introduction

Neurobiology provides an explanation of behaviour or experience at the level either of systems of neurones or individual cells. There is no particular difficulty now in producing accounts of normal emotion and disorders of emotion, based on the currently available techniques for the investigation of brain function. These accounts remain preliminary, but they are no longer purely speculative. However, there has been a curious divorce between the extensive literature on normal emotion and the predominantly clinical or biochemical accounts of mood disorder. It was probably inevitable that the psychology of normal emotion would take a 'top-down' direction, while clinical approaches would be rather more 'bottom-up', dominated by symptoms and the effects of treatments. However, it now seems certain that one field has the potential to inform the other, and that such unifying activity might well take its origins from contemporary cognitive neuroscience. As well as witnessing conceptual advances, we are at a stage of rapid evolution in the platform technologies of imaging and genetics. These will allow us to improve our accounts of the functional anatomy of the component elements of mood and its disorder, their functional neurochemistry, and, in all probability, give meaning to what a cellular account of depressive illness may eventually mean.
