Adult neurogenesis increases in mammals when they are exposed to an enriched environment or given the opportunity to exercise. In this experiment, we investigated whether turtles would show differences in the number of new neurons in the telencephalon when they were exposed to deep water, conspecifics, and plants and logs (EE group), compared to a group of animals housed in individual cages with shallow water (IN group). A control group (EX) was given deep water and conspecifics but no plants and logs. We gave nine injections of BrdU over a 3-week period, starting when the turtles were introduced to the housing. The results showed that both the EE and the EX groups had more new cells in the dorsal ventricular ridge (DVR), a sensory area of the telencephalon. The two groups did not differ from one another. The group-housed animals also had a higher percentage of new neurons in the DVR that were double labeled for NeuN, a marker of neurons, compared to the IN group. There were no significant differences between groups in the number of new cells in the medial cortex, the homolog of the hippocampus. These findings demonstrate that the housing experience influences the number of new cells that survive in the brains of turtles. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

住房经验影响海龟（Chrysemys picta）的成年神经发生。

当哺乳动物暴露于丰富的环境或有机会锻炼时，它们的成年神经发生会增加。在这个实验中，我们研究了海龟在暴露于深水、同种动物、植物和原木（EE 组）时，与单独笼子里的一组动物相比，它们是否会显示出端脑中新神经元数量的差异。浅水区（IN 组）。对照组 (EX) 被给予深水和同种植物，但没有植物和原木。我们在 3 周内注射了 9 次 BrdU，从海龟被引入鸡舍开始。结果表明，EE 组和 EX 组在端脑的感觉区背心室脊 (DVR) 中都有更多的新细胞。两组没有区别。与 IN 组相比，群养动物在 DVR 中具有更高百分比的新神经元，这些神经元被双重标记为 NeuN，一种神经元标记。海马的同系物内侧皮层中的新细胞数量在各组之间没有显着差异。这些发现表明，居住经历会影响海龟大脑中存活的新细胞数量。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。这些发现表明，居住经历会影响海龟大脑中存活的新细胞数量。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。这些发现表明，居住经历会影响海龟大脑中存活的新细胞数量。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
