The Creation of Neuroscience
The Creation of Neuroscience The Society for Neuroscience and the Quest for Disciplinary Unity 1969-1995 Introduction rom the molecular biology of a single neuron to the breathtakingly complex circuitry of the entire human nervous system, our understanding of the brain and how it works has undergone radical F changes over the past century. These advances have brought us tantalizingly closer to genu- inely mechanistic and scientifically rigorous explanations of how the brain’s roughly 100 billion neurons, interacting through trillions of synaptic connections, function both as single units and as larger ensem- bles. The professional field of neuroscience, in keeping pace with these important scientific develop- ments, has dramatically reshaped the organization of biological sciences across the globe over the last 50 years. Much like physics during its dominant era in the 1950s and 1960s, neuroscience has become the leading scientific discipline with regard to funding, numbers of scientists, and numbers of trainees. Furthermore, neuroscience as fact, explanation, and myth has just as dramatically redrawn our cultural landscape and redefined how Western popular culture understands who we are as individuals. In the 1950s, especially in the United States, Freud and his successors stood at the center of all cultural expla- nations for psychological suffering. In the new millennium, we perceive such suffering as erupting no longer from a repressed unconscious but, instead, from a pathophysiology rooted in and caused by brain abnormalities and dysfunctions. Indeed, the normal as well as the pathological have become thoroughly neurobiological in the last several decades. In the process, entirely new vistas have opened up in fields ranging from neuroeconomics and neurophilosophy to consumer products, as exemplified by an entire line of soft drinks advertised as offering “neuro” benefits. -

This 0066-4197/07/1201-0001$20.00 resulted in a cyclic permutation of gene order going from phage to prophage. This contrasted with integration models current at the time, which postulated that the prophage was not inserted into the continuity of the chromosome but rather laterally attached or synapsed with it. This chapter summarizes some of the steps leading up to the model including especially the genetic characterization of specialized transducing phages (λgal ) by recombinational rescue of conditionally lethal mutations. -
Torsten Wiesel (1924– ) [1]
Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) Torsten Wiesel (1924– ) [1] By: Lienhard, Dina A. Keywords: vision [2] Torsten Nils Wiesel studied visual information processing and development in the US during the twentieth century. He performed multiple experiments on cats in which he sewed one of their eyes shut and monitored the response of the cat’s visual system after opening the sutured eye. For his work on visual processing, Wiesel received the Nobel Prize in Physiology or Medicine [3] in 1981 along with David Hubel and Roger Sperry. Wiesel determined the critical period during which the visual system of a mammal [4] develops and studied how impairment at that stage of development can cause permanent damage to the neural pathways of the eye, allowing later researchers and surgeons to study the treatment of congenital vision disorders. Wiesel was born on 3 June 1924 in Uppsala, Sweden, to Anna-Lisa Bentzer Wiesel and Fritz Wiesel as their fifth and youngest child. Wiesel’s mother stayed at home and raised their children. His father was the head of and chief psychiatrist at a mental institution, Beckomberga Hospital in Stockholm, Sweden, where the family lived. Wiesel described himself as lazy and playful during his childhood. He went to Whitlockska Samskolan, a coeducational private school in Stockholm, Sweden. At that time, Wiesel was interested in sports and became the president of his high school’s athletic association, which he described as his only achievement from his younger years. In 1941, at the age of seventeen, Wiesel enrolled at Karolinska Institutet (Royal Caroline Institute) in Solna, Sweden, where he pursued a medical degree and later pursued his own research. -
James D. Watson Molecular Biologist, Nobel Laureate ( 1928 – )
James D. Watson Molecular biologist, Nobel Laureate ( 1928 – ) Watson is a molecular biologist, best known as one of the co-discoverers of the struc- ture of DNA. Watson, Francis Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine. Watson was born in Chicago, and early on showed his brilliance, appearing on Quiz Kids, a popular radio show that challenged precocious youngsters to answer ques- tions. Thanks to the liberal policy of University of Chicago president ROBERT HUTCHINS, Watson was able to enroll there at the age of 15, earning a B.S. in Zoology in 1947. He was attracted to the work of Salvador Luria, who eventually shared a Nobel Prize with Max Delbrück for their work on the nature of genetic mutations. In 1948, Watson began research in Luria’s laboratory and he received his Ph.D. in Zoology at Indiana University in 1950 at age 22. In 1951, the chemist Linus Pauling published his model of the protein alpha helix, find- ings that grew out of Pauling’s relentless efforts in X-ray crystallography and molecu- lar model building. Watson now wanted to learn to perform X-ray diffraction experi- ments so that he could work to determine the structure of DNA. Watson and Francis Crick proceeded to deduce the double helix structure of DNA, which they submitted to the journal Nature and was subsequently published on April 25, 1953. Watson subsequently presented a paper on the double helical structure of DNA at the Cold Spring Harbor Symposium on Viruses in early June 1953. -

The pair also showed that resistance was a heritable trait in the tiny organisms.

Happy Birthday to Renato Dulbecco, Cancer Researcher Extraordinaire
pbs.org http://www.pbs.org/newshour/updates/happy-birthday-renato-dulbecco-cancer-researcher-extraordinaire/ Happy birthday to Renato Dulbecco, cancer researcher extraordinaire Photo of Renato Dulbecco (public domain) Every elementary school student knows that Feb. 22 is George Washington’s birthday. Far fewer (if any) know that it is also the birthday of the Nobel Prize-winning scientist Renato Dulbecco. While not the father of his country — he was born in Italy and immigrated to the United States in 1947 — Renato Dulbecco is credited with playing a crucial role in our understanding of oncoviruses, a class of viruses that cause cancer when they infect animal cells. Dulbecco was born in Catanzaro, the capital of the Calabria region of Italy. Early in his childhood, after his father was drafted into the army during World War I, his family moved to northern Italy (first Cuneo, then Turin, and thence to Liguria). A bright boy, young Renato whizzed through high school and graduated in 1930 at the age of 16. From there, he attended the University of Turin, where he studied mathematics, physics, and ultimately medicine. Dulbecco found biology far more fascinating than the actual practice of medicine. As a result, he studied under the famed anatomist, Giuseppe Levi, and graduated at age 22 in 1936 at the top of his class with a degree in morbid anatomy and pathology (in essence, the study of disease). Soon after receiving his diploma, Dr. Dulbecco was inducted into the Italian army as a medical officer. Although he completed his military tour of duty by 1938, he was called back in 1940 when Italy entered World War II. -
Renato Dulbecco
BIOLOGIE ET HISTOIRE Renato Dulbecco Renato Dulbecco : de la virologie à la cancérologie F.N.R. RENAUD 1 résumé Né en Italie, Renato Dulbecco fait de brillantes études médicales mais est plus intéressé par la recherche en biologie que par la pratique médicale. Accueilli par Giuseppe Levi, il apprend l’histologie et la culture cellulaire avant de rejoindre le laboratoire de S.E. Luria puis celui de M. Delbrück pour travailler sur les systèmes bactéries-bactériophages puis sur la relation cellules-virus. Il met au point la méthode des plages de lyse virales sur des cultures cellulaires. Il est aussi à l’origine de la virologie tumorale moléculaire. D. Baltimore, HM Temin et lui-même sont récompensés par le prix Nobel de médecine et physiologie en 1975 pour leurs travaux sur l'interaction entre les virus tumoraux et le matériel génétique du matériel cellulaire. Très tourné vers les aspects pratiques et expérimentaux de la recherche, il est resté le plus long - temps possible à la paillasse et a initié un très grand nombre de jeunes chercheurs. mots-clés : culture cellulaire, virologie tumorale, plages de lyse, bactériophages.

The Eighth Day of Creation”: Looking Back Across 40 Years to the Birth of Molecular Biology and the Roots of Modern Cell Biology
“The Eighth Day of Creation”: looking back across 40 years to the birth of molecular biology and the roots of modern cell biology Mark Peifer1 1 Department of Biology and Curriculum in Genetics and Molecular Biology, University of North Carolina at Chapel Hill, CB#3280, Chapel Hill, NC 27599-3280, USA * To whom correspondence should be addressed Email: [email protected] Phone: (919) 962-2272 1 Forty years ago, Horace Judson’s “The Eight Day of Creation” was published, a book vividly recounting the foundations of modern biology, the molecular biology revolution. This book inspired many in my generation. The anniversary provides a chance for a new generation to take a look back, to see how science has changed and hasn’t changed. Many central players in the book, including Sydney Brenner, Seymour Benzer and Francois Jacob, would go on to be among the founders of modern cell, developmental, and neurobiology. These players come alive via their own words, as complex individuals, both heroes and anti-heroes. The technologies and experimental approaches they pioneered, ranging from cell fractionation to immunoprecipitation to structural biology, and the multidisciplinary approaches they took continue to power and inspire our work today. In the process, Judson brings out of the shadows the central roles played by women in many of the era’s discoveries. He provides us with a vision of how science and scientists have changed, of how many things about our endeavor never change, and how some new ideas are perhaps not as new as we’d like to think. 2 In 1979 Horace Judson completed a ten-year project about cell and molecular biology’s foundations, unveiling “The Eighth Day of Creation”, a book I view as one of the most masterful evocations of a scientific revolution (Judson, 1979). -
