1 Introduction 1.1 Hemiballism Hemiballism or hemichorea is a rare neurological disorder, but the crucial invol- ment of the subthalamic nucleus (STN) in its pathophysiology has been app- ciated for decades (Jakob 1923; Martin 1927; Glees and Wall 1946; Whittier and Mettler 1949; Carpenter and Carpenter 1951; Crossman 1987). Only recently have serious doubts come forward. Postuma and Lang (2003) have described the STN as being involved in only a minority of cases, and indicated unrecognized causes such as non-ketotic hyperosmolar hyperglycaemia and complications of human immunodeficiency...

Part II starts with a systemic model of the basal ganglia to evaluate the position of the STN in the direct, indirect and hyperdirect pathways. A summary of in vitro studies is given, describing STN spontaneous activity as well as responses to depolarizing and hyperpolarizing inputs, and high frequency stimulation. STN bursting activity and the underlying ionic mechanisms are investigated. Deep brain stimulation used for symptomatic treatment of Parkinson's disease is discussed in terms of the elements that are influenced and its hypothesized mechanisms. This part of the monograph pays...

This volume of Advances in Anatomy, Embryology and Cell Biology is based on material assembled by Dr. Jaap H.R. Schoen. Jaap Schoen published his results only partially himself (see Schoen s references in the preface of Usunoff et al. 1997). After his sudden death, due to a diving accident, Jan Voogd and Hans Feirabend of our Neuroregulation group encompassed his cerebellar results in the chapter on the cerebellum and precerebellar nuclei in Paxinos The Human Nervous System (Voogd et al. 1990), while Kamen Usunoff and myself grouped Schoen s trigeminal results and presented them together with...

This book offers a critical review of the pelvic sciences-past, present and future-from an anatomical and physiological perspective and is intended for researchers, medical practitioners and paramedical therapists in the fields of urology, gynecology and obstetrics, proctology, physiotherapy, as well as for patients.
The book starts with a "construction plan" of the pelvis and shows its structural consequences. The historical background of pelvic studies proceeds from medieval and early Italian models to the definitive understanding of the pelvic anatomy in the Seventeenth century....

The studies described here were carried out in the Neuroregul- ation Group, Department of Physiology, University of Leiden, the Netherlands. Over the last decade, this group, in close collaboration with the Department of Neurosurgery of the Academic Hospital of Leiden, has studied the development of the central nervous system from a neuroanatomical as well as a clinical perspective. During this period, the expression of several morphore- gulators in the developing rat spinal cord was extensively investigated. Parallel studies focused on the development of the spinal cord fiber systems, which...
