__NOTOC__ Joseph Altman is an American biologist who has worked in the field of neurobiology. Altman discovered adult neurogenesis, the creation of new neurons in the adult brain, in the 1960s.〔J. Altman & G. Das, "Postnatal Neurogenesis in the Guinea-pig", ''Nature'', 214, 1098–1101 (10 June 1967). 〕 As an independent investigator at MIT, his results were largely ignored in favor Pasko Rakic's findings that neurogenesis is limited to pre-natal development. In the late 1990s, the fact that the brain can create new neurons even into adulthood was rediscovered by Elizabeth Gould in 1999, leading it to be one of the hottest fields in neuroscience. Adult neurogenesis has recently been proven to occur in the dentate gyrus, olfactory bulb and striatum through the measurement of Carbon-14--the levels of which changed during nuclear bomb testing throughout the 20th century--in postmortem human brains.〔Leonie Welberg, "A striatal supply of new neurons", ''Nature Reviews Neuroscience'', 15, 203 (05 March 2014). 〕 Joseph Altman continued his career at Purdue University, where he wrote several articles and books on cerebellar development. He is now retired. ==Awards== * 2011 Prince of Asturias Award for Technical and Scientific Research. * 2012 International Prize for Biology 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joseph Altman」の詳細全文を読む スポンサード リンク
