In the late 1930s and early 1940s, Wegener and Akelaitis performed partial
and complete callosal sections in humans. At the time, neurological and psychological
examination of patients revealed few positive signs, described as weakly expressed
and transient in nature. Zaidel and Iacoboni's book provides a lively illustration
of how far anatomical, physiological, and behavioral methods have come since
that time. The reader must not expect that the puzzle of what the corpus callosum
does has been solved: to understand what exactly travels across the corpus
callosum, and to what ends, is part and parcel of an understanding of what
the cortex does. Such an understanding eludes us. However, this handsomely
produced and comprehensive volume does inform us about the current state of
research on the corpus callosum and in doing so provides an outstanding illustration
of genuinely interdisciplinary research.
