US-Gabon Cooperative Research: Molecular and Physiological Approaches to the Study of Electrogenesis

该奖项支持康奈尔大学神经生物学教授Carl D. Hopkins博士与加蓬科学技术大学生物系的Brahim Ibrahim博士之间为期三年的合作研究项目。研究人员将研究各种鱼的电器官放电（EOD）波形的变化，以确定变化的系统发育历史以及进化和性别差异在EOD波形中的作用，从而了解变化的形态学和生理学基础。mormyrid鱼是非洲最大的淡水鱼群，只在西非发现，对它们的研究很少。这个合作项目结合了霍普金斯博士在电鱼神经行为学方面的专业知识和易卜拉欣博士在电生理学和药理学方面的专业知识。这项研究将为现有的关于西非mormyrid鱼类及其如何进化的知识提供重要的新信息。该资助还将资助一名初级研究员参加一项国际研究活动。?/¢¥???¥??Á í’？？？？？？？À /¢？__Á？¢A / ? ?©? ? ? ? ?一个? ?¢?¥吗?/ ? ?%¥' ? ?_ ? ? ? ? / ? ?/¥ ?¢¥?¥?¥??¢¥©/¥©/？一个吗?¥©/ ?/¢A / ? ?©? ? ? ? ?一个? ?¥©? ?¢¥? ?一个 ¥¢ ???????%?_ ? _ ? ?Á_Á¥¢/¥¥©？¢一 ?¢¥?¥?¥??¢吗?/ ?一个? ? / AA ?/ ?¢?¥? ?一个吗?©/ AA¢吗?¥©一个? ?_A¥¥吗?一个? ?/ AA¢¥? ?一个¥¢¥吗?¢?? / AA ?¢吗?©现代?¢¥吗?¢”? ?%¥

This award supports a three-year collaborative research project between Dr. Carl D. Hopkins, Professor of Neurobiology at Cornell University, and Dr. Brahim Ibrahim, of the Department de Biologie at the Universite des Sciences et Techniques in Gabon. The investigators will study waveform variations in the electric organ discharges (EOD) of various species of mormyrid fishes to determine the phylogenetic history of the variations and the roles that evolution and sex differences have in the EOD waveform in order to produce an understanding of the morphological and physiological basis for the variations. The mormyrid fishes, which comprise the largest group of freshwater fish in Africa, are only found in West Africa, and little research has been done on them. This cooperative project combines the expertise in electric fish neuroethology of Dr. Hopkins with Dr. Ibrahim's expertise in electrophysiology and pharmacology. This study will contribute important new information to the existing knowledge about the mormyrid fishes in West Africa and how they have evolved. The grant will also provide support for a junior investigator to participate in an international research activity. ?/¢¥???¥??Á í` ???????À / ¢?__Á? ?Á¢Á/??© Á??Á??Á?Á Â?? ??¢?¥?À Â/??%¥` Â??_ ??Á?À?/??/¥Á ?¢¥?¥?¥??¢ ¥©/¥ ©/?Á ?¥ ©/? / ?Á¢Á/??© Á??Á??Á?Á Â?? ¥©Á?? ¢¥??Á¥¢ ???????%?_ ?_????Á_Á¥¢ /¥ ¥©?¢Á ?¢¥?¥?¥??¢ ?/ ?Á Á????/ÀÁ? /? ??¢?¥??Á ?©/ÀÁ¢ ? ¥©Á Á????_Á¥ ¥?
