Purporting to be a glossary of neurological and psychological terms, this book is actually only an alphabetical list of 591 miscellaneous nouns, adjectives and eponyms such as might casually be remembered from extensive but careless and superficial reading, ranging from anatomy and surgery to clairvoyance and telepathy.

As for the definitions, intended by the author to cover 'the broader and larger aspects' of the terms, they usually contain some grain of truth, and are often lightened by unintentional humor or a unique use of words.
