For many years Professor Seeger has held microanatomical courses for young neurosurgeons and neuroradiologists. Many ideas in his new book have developed from discussions with experienced colleagues and young residents. The author presents anatomical variations from the normal anatomy which may necessitate a modification of the standard operative procedure. Special emphasis is put on the presentation of the temporal lobe, and the potential anatomical causes for complications during amygdyla-hippocampectomies (hemiparesis, aphasia, neuropsychological syndromes) are shown. Special radiological projections are complemented by anatomical drawings of fine structures such as N. oculomotorius and N. opticus and presentations of the hippocampus or the Circle of Willis.
