Lazaros C. Triarhou – författare

The book comprises biographical notes, of about 1000 words each, with a portrait photo, of 90 influential figures of the famous prewar Viennese school of neuropsychiatry, appearing together for the first time in a single volume. The entries focus on the academic lives and scientific contributions of pioneers in the neurological sciences viewed from a modern perspective. These updated profiles are based on substantial new research. The book includes a wide range of people, some famous Nobel laureates, and others less well known, from the era when Vienna was the epicenter of brain research. Despite the tragic circumstances of two World Wars, these pioneers remained resilient, willing to help others with an admirable dignity against adversity that leaves an indelible lesson to the later generations. Some fell victim of the Holocaust. Others overcame the constraints of National Socialism and ultimately settled overseas to nurture their ambitions and pursue their intellectual goals as physicians, researchers, and teachers. The monograph is a useful source for scholars interested in the evolution of ideas in basic neuroscience, clinical neurology, and neuropsychiatry, and the investigators who effected them.

Parkinson's disease, a degenerative brain disorder, affects an estimated 0.25-0.50% of the population. Symptoms result from neuronal degeneration in the nigrostriatal dopaminergic pathway and include tremor, rigidity and gradual slow- ness of spontaneous movement. The cause of Parkinson's disease is only partially understood; both environmental factors and a genetic predisposition have been im- plicated in its etiopathogenesis. Neural transplantation is being used experimentally for providing an alternative biological source of dopamine both in animal studies and in experimental clinical trials. This book is the result of 15 years of research on the transplantation of dopaminergic neurons in the striatum of the weaver mouse, a neurological mutant characterized by genetically-determined degeneration of midbrain dopamine neurons. The weaver mouse constitutes the only available laboratory model with a chronic progressive disease that mimics Parkinsonism.The other two models currently used to investigate dopaminergic mechanisms rely on the use of the neurotoxins- hydroxydopamine and methylphenyltetrahydropyridine for the selective removal of dopaminergic neurons from an otherwise healthy organism. Structural and functional aspects of transplantation of mesencephalic dopamin- ergic grafts into the striatum of weaver mice are reviewed, including histochemical correlates of graft survival and integration, numerical aspects of donor neuron survival, ultrastructural findings on synaptogenesis, neurochemical indices of dopam- ine uptake function and receptor binding, gene expression of several structural and neurotransmitter-receptor related molecules, the levels of striatal amino acid receptors, and the behavioral effects of unilateral and bilateral neuronal transplantations.
