When the first edition of Clinical studies in Neuro-Psychoanalysis was published in 2000, it was hailed as a turning point in psychoanalytic research. It is now relied on as a model for the integration of neuroscience and psychoanalysis. It won the NAAP's Gradiva Award for Best Book of the Year 2000 (Science Category) and Mark Solms received the International Psychiatrist Award 2001 at the American Psychiatric Association's annual meeting. The authors have added a glossary of key terms of this edition to aid their introduction to depth neuropsychology. 'Freud, in his 1895 Project for a Scientific Psychology, attempted to join the emerging discipline of psychoanalysis with the neuroscience of his time. But that was a hundred years ago, when the neuron had only just been described, and Freud was forced - through lack of pertinent knowledge - to abandon his project. We have had to wait many decades before the sort of data which Freud needed finally became available. Now, these many years later, contemporary neuroscience allows for the resumption of the search for correlations between these two disciplines.
