The body of the text consists of questions posed by Dr. Healy, in italicized type, and the responses of the psychopharmacologists. For example, in the first chapter, the interview of Pierre Pichot, the opening question is, "Could we begin with your recollections of the 1955 Paris meeting, which was effectively the first world-wide meeting on chlorpromazine?" The answer that follows is obviously the opinion of one individual, but it offers an insight and historical overview that is available only from those who were there.
