Brain Explorer Santiago Ramón y Cajal Santiago Ramón y Cajal ForMemRS (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 18 October 1934) was a Spanish pathologist, histologist, neuroscientist and Nobel laureate. His original pioneering investigations of the microscopic structure of the brain have led him to be designated by many as the father of modern neuroscience. His medical artistry was legendary, and hundreds of his drawings illustrating the delicate arborizations of brain cells are still in use for educational and training purposes. Biography The son of physician and anatomy lecturer Justo Ramón and Antonia Cajal, Ramón y Cajal was born of Aragonese parents in Petilla de Aragón in Navarre, Spain. As a child he was transferred between many different schools because of his poor behavior and anti-authoritarian attitude. Over the summer of 1868, Cajal's father, hoping to interest his son in a medical career, took him to graveyards to find human remains for anatomical study. Works and theories
RadioBlagon Neuranat : un site de neuroanatomie Morphologie Ce chapitre aborde les bases de l'anatomie descriptive du crâne, des méninges et du système nerveux central. Atlas Ce chapitre propose des atlas anatomiques interactifs dans les trois plans, un atlas neuroradiologique avec curseur 3D synchronisé dans les trois plans de l'espace et un atlas du tronc cérébral de l'espace neuroradiologiques, montrant un point choisi au niveau du cerveau simultanément dans les 3 plans de l'espace et sur une reconstruction 3D ainsi qu'un atlas du tronc cérébral. Vidéos Le chapitre Vidéos constitue un véritable atelier de dissection du cerveau grâce à des documents richmédia associant simultanément vidéo, images et textes. Animations Retrouvez des animations concernant la fissure choroïdienne, le fornix et le quatrième ventricule et un "serious game", Dyn@slice, permettant de s'exercer à remettre dans l'ordre des coupes de cerveau. © UPMC.
Chapter 1: Introduction An understanding of functional neuroanatomy is critical to understanding the symptoms of nervous system damage. Most disorders of the nervous system either target particular brain structures or target components of functional systems. Therefore, knowing these structures and their basic functions permits localization of the nervous system damage. This chapter will consider the important elements of clinical neuroanatomy. There are several good texts that provide greater detail on these systems (1-3). An atlas of brain structures is essential to the study of neuroanatomy. This review will discuss the cellular components of the nervous system first and then will consider the peripheral nervous system (PNS) before discussing the Central nervous system (CNS). 1. 2. 3. 4.

Sexual orientation – wired that way In a recent post, I presented the evidence that sexual preference is strongly influenced by genetic variation. Here, I discuss the neurobiological evidence that shows that the brains of homosexual men and women are wired differently from those of their heterosexual counterparts. First, we must consider the differences between the brains of heterosexual males and females. These differences are extensive and arise mainly due to the influence of testosterone during a critical period of early development (see Wired for Sex). They include, not surprisingly, differences in the number of neurons in specific regions of the brain involved in reproductive or sexual behaviours as well as differences in the number of nerve fibres connecting these areas. But they also involve areas not dedicated to these types of behaviours, such as the cerebellum, for example, which is involved in motor control among other things, and which shows a very large difference between men and women.

Chapter 9: Limbic System The limbic system is a convenient way of describing several functionally and anatomically interconnected nuclei and cortical structures that are located in the telencephalon and diencephalon. These nuclei serve several functions, however most have to do with control of functions necessary for self preservation and species preservation. They regulate autonomic and endocrine function, particularly in response to emotional stimuli. They set the level of arousal and are involved in motivation and reinforcing behaviors. Areas that are typically included in the limbic system fall into two categories. One way in which the limbic system has been conceptualized is as the "feeling and reacting brain" that is interposed between the "thinking brain" and the output mechanisms of the nervous system. Hypothalmus The hypothalamus, the primary output node for the limbic system, has many important connections. Some functions are intrinsic to the hypothalamus. Amygdala Hippocampus Limbic cortex
