The first edition of this bestseller laid the groundwork for understanding the female brain, examining the evidence of structural and functional differences between the brains of males and females. Addressing a wealth of new research, the second edition continues in this vein, leading readers through the basic principles of anatomy and physiology and on to the complex behavioral functions which constitute the workings of the normal and abnormal female brain. Filled with rigorous scientific analysis in an easily accessible format, the book delineates gender-based differences between brains and explains why they should be considered when designing research and clinical studies.
