In Vivo Atlas of Deep Brain Structures

In the first half of the twentieth century, the study of neuroanatomy was essentiallybased on the observations made by scientists on brain cadavers fixed with standard techniques. These studies have produced well-known tools such as the stereotactic atlas, which have proven to be extremely useful and irreplaceable for neurosurgeons, neuroradi­ ologists, neurologists and neuroanatomists. In particular, the Talairach and Schaltenbrandt atlases are considered the most presti­ gious and up-to-date work available today. The recent introduction of neuroimaging, especially nuclear magnetic resonance, together with the exciting and tremendous progress made in computer graphics, has allowed us to approach neuroanatomy directly in living patients with more accuracy and a high degree ofdetail. This work, after a short introduction which explains the methodolo­ gy used, is divided into four types of sections: three types ofsections obtained from the same brain and orientated in the standard axial, sagittal, and coronal spatial planes and one type of section of three­ dimensional pictures obtained from the computerized processing of the previous pictures. The organization and the life-size tables obtained by magnetic reso­ nance make this work similar to a classic stereotactic atlas, although the authors do not claim to reach the high level of precision which such atlases usually provide. The abbreviations used are based on Latin nomenclature,in order to be understood and recognized world­ wide, and are supported by a system of color codes useful for the identification ofbrain structures.
