| 摘 要： | 罗氏沼虾（Macrobrachium rosenbergii)的脑位于两个眼柄基部中的一团海绵状组织内，它由神经根、前脑、中脑、后脑、神经连接和细胞体群组成，它的神经根从脑发出的位置及外伸的方向和已描述对的虾、蟹的脑神经根有一定的区别，未发现有副叶髓质和中脑连接，因此它可能是虾蟹另一种脑的类型。

| Abstract: | The brain of the prawn Macrobrachium rosenbergii is located in a mass of spongy tissue within the base of eyeslalks. It consists of protocerebrum, deutocerebrum, tritocerebrum, nerve roots, commissures, and clusters of cell bodies. It is different from the described brains of the other prawn and crabs in the site where the nerve roots project from the brain and in the extension directions of the nerve roots. In the brain the accessoty lobe, a neuropil, and the deutocerebral commissure could not be identified. The above differences suggest that the brain of Macro-brachium rosenbergii may he a new brain type of the prawns and crabs. |
