For those interested in the structure and function of human auditory cortex, there is a brand new book in the Springer Handbook of Auditory Research (SHAR) series on precisely that:
Poeppel D, Overath T, Popper AN, Fay RR (eds) (2012) The Human Auditory Cortex. Springer Science+Business Media, LLC, New York.
The SHAR series is aimed at graduate students, new postdoctoral investigators, investigators already working on other aspects of the auditory system, clinicians and clinical researchers, and individuals with interests in hearing.
The book is divided into two parts: the methods section introduces the main methodologies available to study the human auditory cortex (anatomy, invasive recordings, EEG, MEG, fMRI), while the second part covers such topics as processing of basic acoustic parameters, auditory objects, speech, music, multisensory as well as spatial information, before culminating in a tour-de-force synopsis and theory of everything auditory.
This is the Springer link, which includes a more detailed description and chapter list:
The book is obviously also available at Amazon etc.
