The need in medicine and basic science for a sophisticated knowledge of human brain anatomy is greater now than ever before. Clinically, the emergence of ever more sophisticated brain imaging modalities and continually increasing capacity to precisely target specific sites for deep brain stimulation and focal lesions demand that neuroanatomical knowledge of the human brain keeps pace. Tremendous progress during the last thirty years in revealing details of neural connections and principles of organization of animal brains demands that the basic neuroscientist discern what these principles...

Times of dramatic progress in brain research have often been correlated with the development of new and powerful techniques that have changed the kinds of questions one can ask. An historical example may illustrate the point. More than 50 years ago, Nissl studies (Ferraro, 1928) showed that extensive forebrain lesions resulted in chromatolysis and cell loss in the sub- stantia nigra; thus, it was suggested that the substantia nigra gave rise to projections into the basal forebrain. In the late 1950s, another clue emerged, this time linking observations from the field of neuropathology with a...
